Polymarket Prediction Market Trading Bot

Polymarket Prediction Market Trading Bot: International and US Are Separate Integrations

Polymarket maintains separate International and US developer documentation and account workflows. ProfitBot’s account-region buttons reflect that distinction. International is the initial visible selection, but the user must select the profile that matches their permitted account.

Keys for one environment must not be sent to another service. The connection workflow should identify the endpoint family and expected authentication before making an authenticated request. Changing a label in the interface is not sufficient to transform an International integration into a US integration.

An accepted API key establishes only part of the account context. Review market identifiers, available funds, order permissions and settlement records within the selected profile. Two products using the Polymarket name do not imply interchangeable credentials, order details or balances.

Tie Forecasts to Outcomes and Current Rules

A prediction strategy should identify the exact outcome it values. Record the market’s terms, outcome mapping and relevant timing alongside a forecast. A broad explanation of an event is not enough if the contract depends on a specific threshold, source or deadline.

Probability estimates should be available before the trading decision. Keep their evidence and timestamp so a later review can distinguish a genuine forecast from information learned afterward. A model’s confidence language does not establish numerical calibration.

Configure a minimum estimated advantage only after accounting for the executable price and costs. The estimated advantage can disappear if a book is thin, a quote is stale or the available quantity is smaller than the desired position.

Track Open Orders as Portfolio Commitments

A submitted order may remain open or fill partially. Until its final state is known, it can still change the account’s inventory. Count those outstanding commitments when deciding whether another order fits the strategy’s capital limits.

Cancellation also has a lifecycle. The strategy should not free all reserved risk merely because it requested cancellation. Reconcile any fills that occurred before the cancellation took effect and update the position that remains.

When a process restarts, refresh authenticated account state and recover known order identifiers. A successful market-data request does not establish that the order journal is complete. The risk layer needs the account’s actual commitments before permitting fresh activity.

Review Settlement and Access Before Deployment

A prediction market position can remain exposed after trading stops. Understand the selected contract’s resolution and settlement path, what actions the account may need to take and how the bot will record the resulting balance change.

Use the probability source, capital and risk settings to define a decision you can explain before an order is placed. Compare the forecast with an executable price and review the effect of fees. Preserve the account profile beside the order record so that its permissions and settlement terms remain clear.

Your Polymarket account’s eligibility, current platform rules and available instruments control which markets you can access. Read the rules for each contract and keep credentials within their intended profile. An interface setting cannot override a platform restriction or make another region’s account equivalent to your own.

Choose Polymarket International or Polymarket U.S. First

A Polymarket prediction market trading bot must identify the service before it configures an account. Polymarket International and Polymarket U.S. have separate accounts, credentials, market availability and operating requirements. ProfitBot exposes the Account Region choice as visible buttons so that the distinction remains clear while you connect an account and prepare strategies.

International is the initial selection in the workspace. Choose the service you are eligible to use before entering credentials or saving a profile. Selecting a different region in the app does not transfer balances, convert an account or bypass a restriction. The provider's eligibility and geographic requirements continue to apply to the account and markets you access.

A familiar event title can appear in different services without having identical contract terms. Read the specific market's rules, deadline and settlement process. Do not copy an estimate or order instruction between profiles merely because the names look alike. The service, account, market and outcome together define the scope of the trading decision.

This separation also matters when you review history. A position in the International account is not a position in the U.S. account, and a credential replacement should not overwrite the meaning of earlier records. Keep profile-specific strategy names and account identifiers visible so that a combined view does not obscure where a particular order or obligation exists.

Connect API Access Without Confusing It With a Trading Wallet

API authentication and account funding answer different questions. A valid credential can establish access to an account function without proving that the account has the required balance or that the intended signer controls the relevant assets. Follow the fields and protected native prompts for the selected Polymarket profile rather than assuming that one credential format works for both services.

For the International profile, review the relationship among the authenticated account, signing identity and any wallet or funding address required by the supported connection. A mismatch can produce misleading balances or an unusable order path. For the U.S. profile, use the credentials issued for that account and the requested key identifier and signing material. Do not place an International credential into the U.S. form.

Keep private credentials in the local account workflow. The public licensing website needs public wallet associations and ownership proofs, not a trading secret. Support can help interpret an error or public identifier without receiving the key that authorizes account actions. If a key is exposed, revoke it with the provider and reconnect using a replacement.

After authentication, inspect balances, positions, open orders and account restrictions. An “authenticated” state is one prerequisite, not an assertion that the account is ready for every contract. Existing orders can reserve funds, and a market can have requirements independent of the account login. Review those conditions before allowing a strategy to commit capital.

Read the Market, Outcome and Resolution Source Together

A Polymarket event can contain one or more markets, and a market can refer to specific outcomes. The headline alone is not the full trading target. A reviewed estimate and order must remain associated with the exact supported market and outcome rather than a loose event description or a price copied from a neighboring contract.

Read how the outcome is resolved. Identify the authoritative source, deadline, applicable time zone and any qualification about revisions or exceptional circumstances. A question about whether something happens by a deadline differs from one about an observation at a specific moment. Those details can change the probability substantially even when both questions refer to the same subject.

Consider an illustrative event containing several candidate outcomes. Buying one outcome does not necessarily mean that every other listed outcome is its exact complement. Some sets can be mutually exclusive, while others can overlap or leave additional possibilities. Determine the contract relationship from its rules before calculating a portfolio as though the outcomes form a simple exhaustive set.

Keep a record of the rules relevant to your forecast. If new information changes the interpretation or the provider updates a material term, review the estimate rather than reuse it automatically. A well-explained probability for the wrong definition is not a valid input to the order you are about to place.

Build a Polymarket Trading Strategy Around an Independent Estimate

The Probability Estimate Source control lets you select a Manually Reviewed Estimate or a Reviewed External Model. The chosen probability should describe the selected outcome under its actual rules. It should not be a rephrasing of the current contract price presented as independent knowledge. A strategy needs a reason to think the expected payout justifies the executable cost.

For a manual estimate, save the strategy draft, identify the market and outcome, enter the assessed probability, explain the rationale and set a validity period. The rationale should distinguish observed facts from assumptions and identify information that would change your view. A short, confident sentence without a source or condition is difficult to review when the market moves.

An external model should be evaluated in the same spirit. Ask what information it uses, how current that information is and whether it understands the resolution rule. A model trained to forecast a broad event can be unsuitable for a narrowly defined contract. Its numerical precision should not be mistaken for a precise understanding of the outcome.

Retain the estimate that was valid at decision time. Rewriting a losing forecast after settlement makes the historical record less useful. A practical Polymarket automation process keeps the contract, estimate, order quote and actual outcome connected, so that you can distinguish forecast error from an execution decision that paid too much.

Translate Probability Into an Executable Net Edge

For a simple hypothetical $1-or-$0 outcome contract, a 58% estimate represents an expected payout of $0.58 before costs and other constraints. If the available acquisition cost is $0.54, the gross modeled difference is four cents per contract. That difference is uncertain expected value, not an immediate or guaranteed four-cent profit.

Fees and execution conditions reduce the available margin. The strategy's Minimum Edge After Fees and Slippage should use the actual quote and the fee information applicable to the selected market and profile. Do not assume that every market or every order role has the same fee schedule, and do not reuse an outdated fee estimate when the route or account conditions change.

Price bounds provide another constraint. A nominal difference near an extreme price can produce a different return and loss profile from the same difference near the middle of the payout range. Minimum and Maximum Contract Price let you define which region the hypothesis is intended to cover. Those bounds should reflect the reasoning, not simply include every possible price.

Review basis-point units carefully. In the prediction editor, one basis point of a $1 payout is $0.0001; 100 basis points is one cent. A 300-basis-point minimum edge is therefore three cents on that basis, not automatically a 3% return on the amount spent. Use consistent units when comparing probability, quoted price, fees and permitted slippage.

Use Fresh Book Depth Rather Than the Last Trade

The last traded price describes a previous execution. It does not guarantee that your desired quantity is currently available at that price. The best ask may cover only a small amount, and a larger buy may need to consume higher-priced levels. A sale faces the corresponding question on the bid side. Review the average executable cost of the intended position.

Maximum Bid/Ask Spread and Minimum Executable Book Depth address different aspects of liquidity. A narrow spread can coexist with very little size. A large amount of historical volume can coexist with an empty current book. The strategy should use the relevant fresh depth rather than assume that an active-looking event will support any requested quantity.

Maximum Order-Book Age limits how long the snapshot remains acceptable for the decision. That clock is separate from the age of the probability estimate. A current forecast cannot make an old quote executable, and a fresh quote cannot make an outdated forecast informed. Both inputs need to satisfy their own requirements before an order is considered.

If the current price removes the required edge, the appropriate result can be a rejected order. A previous attractive spread between estimate and price does not remain reserved for the account. Do not widen the slippage tolerance simply to preserve the feeling that you found an opportunity earlier in the session.

Track Open Orders, Partial Fills and Cancellations

A Polymarket order has a state beyond “sent.” It may be accepted and open, partially filled, fully filled, canceled or unresolved after an uncertain response. Each state affects the account's available funds and exposure. The app should preserve the order identifier and relevant fills so that a later review can establish the actual commitment.

An unfilled order can become inappropriate after new information arrives. Cancel Unfilled Order After sets a time policy for that commitment, but a cancellation request still needs a final result. A fill can occur while cancellation is in progress. Reconcile the completed quantity and remaining order state before placing a replacement that assumes nothing executed.

Partial fills require both inventory and reservation accounting. The filled portion creates a position; the unfilled portion may still reserve capital and may execute later. Another strategy should not count the reserved amount as free merely because the entire intended position is not yet visible. The combined obligation matters to the allocation and position limits.

After a timeout or reconnect, check the original order identity rather than submit a new order immediately. The provider may have accepted the first request even if the response did not reach your device. A deliberate reconciliation step is more reliable than treating every interrupted request as an unsuccessful trade that can safely be repeated.

Set USD Risk Limits Without Ignoring Account Collateral

The prediction strategy expresses capital limits in USD, but the actual account must hold the balance and collateral appropriate to its selected service. The USD label in the header is a reporting and configuration cue, not permission to assume every funding asset is interchangeable. Confirm the available balance and any conversion or transfer requirements in the account workflow.

Allocated Capital, Maximum Position Cost and Total Open and Pending Exposure should describe the amount the strategy is allowed to commit. Open and Pending Positions adds a count boundary, while Maximum Correlated-Event Exposure limits concentration in related outcomes. Resting orders remain part of the calculation until they are resolved.

As an illustrative configuration, a $1,000 allocation could have a $25 position-cost ceiling and a $100 aggregate ceiling. Four positions at that cost would use the full aggregate amount before other constraints. These figures explain the relationship between the fields; they are not recommended settings. The actual balance, depth, fees and loss tolerance determine what is appropriate for your account.

Review capital after settlement, withdrawals and credential changes. A visible total balance can include funds unavailable for a new order. Expected proceeds are not spendable simply because an event appears decided in the news. Use the provider's reconciled account state rather than a mental estimate of what should soon become available.

Control Exposure Across Related Polymarket Outcomes

Several Polymarket contracts can respond to the same underlying event or data source. Buying them in separate orders does not create independent risk. A common information update can move the entire group together, and similar themes may also appear in the Kalshi account or a meme coin strategy. Review both local and combined exposure.

Mutually exclusive outcomes need coherent assumptions. If only one outcome can occur, separately assigning high probabilities to several of them may describe an impossible joint view. Overlapping questions create a different challenge: one event may satisfy several contracts, but small rule differences can leave a position exposed in a way the headline comparison misses.

The correlated-event limit is a monetary boundary for that common dependency. It supplements the per-position and aggregate limits rather than replacing them. A strategy can fit its count ceiling while still concentrating nearly all allowed risk in one event family. Keep the rationale for grouping related positions visible in your review.

Do not call a pair of positions a hedge solely because one is labeled Yes and the other No. They must refer to the relevant complementary outcomes under compatible rules and execution conditions. If the contracts differ by service, deadline or resolution source, the remaining mismatch can be the dominant risk rather than a minor technicality.

Plan Around Resolution, Disputes and Exit Timing

A prediction contract's lifecycle extends beyond order entry. Read when trading closes, how the outcome is determined and what happens if the result is disputed or delayed. A public event becoming clear and the account receiving settled funds are distinct stages. A strategy should not reuse expected proceeds before the relevant account record makes them available.

Choose whether the plan seeks an earlier exit or continued exposure toward resolution. Maximum Holding Time and Exit Before Resolution define part of that policy. A buffer is useful only if it leaves enough time for the supported order workflow under the market conditions you face. It is not a guarantee that a buyer will be available for the full position at the desired price.

Stop-loss and take-profit triggers also depend on executable liquidity. A displayed mark can be favorable while the actual bid for the intended quantity is much lower. New information can move the market through a stop level before a sale completes. Size positions with those possibilities in mind rather than relying on a trigger to make the ultimate loss impossible.

After an exit, reconcile the fills and remaining quantity. A partially sold position still depends on later market or resolution outcomes. Keep that residual exposure in the account's risk view. A clean final record distinguishes proceeds from sale, any remaining contract claim and funds that have actually settled.

Use AI Assistance Without Letting It Invent Certainty

An AI assistant can help summarize the rule text, identify ambiguous assumptions or explain the relationship between probability and price. It can also miss a qualification, confuse the International and U.S. services or supply a confident estimate unsupported by the available facts. Review the source material and the account context rather than relying only on the tone of the answer.

Use specific prompts. Ask which details in a contract definition affect an estimate, what information would invalidate a rationale, or whether several proposed positions share an event risk. A request for guaranteed profitable contracts asks the model to promise something the market cannot supply. Keep the task connected to an observable part of your decision process.

Grok Bot through xAI, Claude and ChatGPT require your own API access when used. Set a spending budget and protect credentials in the local connection workflow. Do not include account secrets or recovery phrases in prompts. A provider response is a proposal for review, not permission to exceed the app's independent account, license and risk limits.

Save any accepted strategy change as a new revision and keep the market-specific forecast record. An unsaved conversation is not a reliable reference for why an order was authorized. This separation makes later analysis more useful because the actual parameters and evidence remain identifiable regardless of how an assistant might explain the result afterward.

Review Polymarket Results With a Consistent Scope

Begin with the selected service, account and time period. Separate realized proceeds from open-contract valuations and identify orders or settlements that remain unresolved. Include fees, execution differences and partial fills. A correct event forecast can still produce a poor trading result if the account pays too much or cannot exit as intended.

Assess estimates and order handling separately. Review whether probability assessments were reasonable given the information available at the time, and then review what the account actually paid or received. A short winning sequence does not establish calibrated forecasting. A losing contract does not by itself prove that the earlier probability assessment was irrational.

Use the app's positive P&L sharing workflow only for the eligible verified scope it calculates. The resulting graphic communicates a selected realized result, not a complete account performance claim. If an approved affiliate referral is included, review both the visible URL and the caption and disclose the relationship when posting.

The setup guide covers both Polymarket profiles, protected account connections and strategy fields. The license page lets you choose duration; every paid plan includes all nine simultaneously active markets. A Polymarket prediction market trading bot should preserve a clear relationship among the correct service, exact outcome, reviewed probability, current executable price and reconciled account result.

A Polymarket Prediction Market Trading Bot Account Checklist

Before choosing a contract, confirm whether your eligible account belongs to Polymarket International or Polymarket U.S. Keep the corresponding credentials, balances and order history within that profile. A successful connection to one service does not grant access to the other. Read the selected service's account requirements and the rules attached to the instrument you intend to trade. This is particularly useful for users who follow market prices from several websites, because a price visible in a public discussion may refer to a contract or service that differs from their own account.

Review the exact outcome and the market identifier alongside its displayed question. If two contracts concern the same public event, compare their resolution conditions before treating their prices as interchangeable. A difference in timing, source or definition can explain a price gap. The strategy should use the probability estimate appropriate to the specific contract. A high-confidence opinion about a broad event is not enough when the purchased outcome depends on a narrower condition that the original forecast did not actually evaluate.

Then inspect the account's available funds, current orders and related positions. A pending order can reserve capacity even before it creates a fill. If you change your target price, review the original order's status before increasing the total amount committed. Partial fills deserve their own record because they create real inventory while leaving an outstanding remainder. The same care applies near a contract deadline, when an intended cancellation or exit may compete with rapid changes in liquidity. A decision to leave the market is only complete when the account's resulting state confirms it.

Use the final record to compare your estimate, actual entry price, fees, exit or settlement and remaining commitments. Keep International and U.S. results clearly attributed to their account profiles. This prevents different contract rules or costs from being blended into an unexplained performance number. A Polymarket prediction market trading bot can make a disciplined workflow easier to follow, but the discipline still comes from using the correct account, reading the precise question and sizing an order according to executable terms. A recognizable event headline should never replace those checks.
