A crypto prediction market bot needs two coherent histories: what is known about the event and what has happened in the account. A source update can change a forecast without changing any holdings. A delayed fill can change holdings without changing the event. Combining both into one status such as active or finished makes it difficult to decide what the system is permitted to do next.
This guide describes an educational architecture using a fictional price-event workflow. It does not provide a live trading integration or claim that a particular venue supports every illustrative feature. Actual account eligibility, data access, order semantics and price increments must be verified for the selected product. The design goal is to make each observation, authorization and financial commitment explainable after interruptions as well as during ordinary operation.
Crypto Prediction Market Bot Event State Describes Evidence
The event record should identify the contract condition, reference source, observation window, threshold operator and rule version. It then records what evidence has arrived and whether that evidence is usable for the intended forecast. A source can be current, stale, missing or in conflict with another observation without the contract itself having resolved.
Avoid treating all new data as equally meaningful. A price observation from the designated reference can update the event estimate, while a quote from an unrelated chart may be contextual only. A rule clarification can require a mapping review rather than a numerical forecast update. The event record should preserve the type of change and its practical effect.
A fictional event might move from waiting for its observation window to collecting valid reference evidence, then to observed but not officially determined, and finally to a verified determination. These are conceptual states for the design, not asserted venue status names. The actual adapter should map authoritative records into a documented interpretation.
The older event contract bot guide explains the full data-to-reconciliation lifecycle. Separating event evidence is a useful refinement because it prevents a bot from assuming that an account action occurred merely because the external world reached a new milestone.
Crypto Prediction Market Bot Account State Describes Commitments
The account record should distinguish recommendations, authorized instructions, submitted attempts, accepted orders, confirmed fills, remaining open quantities and completed settlement records. Each establishes a different fact. A recommendation can exist without permission to trade, and an accepted order can exist without the intended position having filled.
The record also needs funding and reservations. Available balance, committed purchase amounts, possible future fills and unresolved transfers should not be mixed into one cash field. A bot authorizing a new action needs to know what could still change the account from instructions already sent.
Polymarket's order-lifecycle documentation distinguishes orders from subsequent trade progress. Other account contexts need their own current mappings. The bot should not infer finality from a generic success response or assume that every partial fill leaves a persistent remainder.
The older prediction market bot API guide provides the interface boundaries behind this design. The account state is not a local guess about what should have happened; it is a reconciled interpretation of authoritative order, fill and balance evidence.
Connect the Histories Through a Bounded Authorization
A forecast can propose a specific claim, side, quantity and price range. A risk decision should then check contract identity, evidence freshness, current account exposure and available capital before granting a bounded authorization. The executor receives that authorization, not an unlimited instruction to act on every subsequent signal.
Include the forecast and rule versions, maximum quantity, total cost bound and expiration in the permission record. If a material input changes before submission, the executor should verify that the existing permission still applies or request a new bounded decision through the designed workflow. A recommendation should not remain actionable indefinitely.
This separation allows the bot to observe continuously without continuously increasing authority. Most source updates may require no trade. The system can record new evidence, revise an estimate or abstain while leaving account commitments unchanged. Inactivity can be the correct response to a changed event state.
The related crypto prediction market software guide describes how to evaluate evidence and auditability in an application. A useful acceptance test should show the exact record that connected one forecast to one authorized commitment, including the checks that bounded it.
Work Through a Capital Authorization
Suppose a fictional account has a $120 strategy commitment limit, with $20 already reserved for another possible obligation. A new recommendation requests up to 200 Yes units at no more than $0.55, with a $4 charge allowance. The possible new requirement is $114, and combined commitments could reach $134. The request exceeds the limit.
Under a fictional whole-unit sizing rule for this example, the available $100 must cover purchase spending and the $4 allowance. That leaves $96 for units. Dividing by $0.55 gives about 174.54, so a maximum of 174 whole units fits: $95.70 of purchase spending plus $4 charges, or $99.70, alongside the existing $20 reservation.
This is a design calculation, not a claim about a venue's minimum quantity or precision. Actual sizing must use the current market's allowed increments. The bot should also reject the recommendation if the $4 allowance is not sufficient for verified applicable costs, rather than treating the allowance as a promise that costs cannot exceed it.
The authorization now describes 174 units, not the original 200. Both records should remain visible: the recommendation explains what the model proposed, while the authorization explains what the account could permit. A later review should not mistake the reduction for an execution failure.
Preserve Actual Fills as They Arrive
In the fictional sequence, 100 units fill at $0.52 for $52 and another 50 fill at $0.54 for $27. Purchase spending is $79, and confirmed charges so far are $2. The account owns 150 units at an $81 all-in cost. Twenty-four of the authorized 174 remain unfilled under the example's persistent-order behavior.
Those 24 can still create up to $13.20 of purchase spending at the $0.55 limit. If the design retains the remaining $2 of charge allowance for this commitment, the position plus possible remainder totals $96.20. Add the separate $20 reservation and potential commitments are $116.20 under the stated accounting assumptions.
The bot should derive these values from unique fills and the remaining order state. Duplicate notifications must not add quantity twice. Out-of-order delivery should not make an older account snapshot overwrite a later verified fill without reconciliation. Preserve the source identities and ordering information supported by the actual interface.
The older automated odds trading guide separates feeds from authority. That distinction is visible here: the same event forecast can remain unchanged while account evidence steadily changes the amount held and the capacity available for the next decision.
A Source Failure Must Not Erase the Position
Now suppose the designated event feed becomes unavailable. The event state should record that the evidence required for new forecasts is uncertain. The bot may pause new recommendations or revoke unexecuted permissions according to its policy. It should not set the existing position to zero or assume that external orders have disappeared.
The account process continues. It still needs to reconcile fills, inspect open commitments and apply the predetermined response to stale event evidence. If the plan requires canceling the 24-unit remainder, the cancellation is an account action with its own pending and final states. A feed outage is not proof that the cancellation succeeded.
This separation helps an operator understand the incident. The source problem affects confidence in new decisions, while the account records establish current exposure. A clear alert says which evidence is missing, which orders remain possible and what actions are blocked. A single disconnected status cannot communicate all three.
The related crypto event markets article examines varied event conditions. Different source failures can have different implications for those conditions, so the bot should not apply one universal fallback source or outcome assumption to every market it monitors.

Cancellation Can Race With Execution
During the fictional cancellation interval, ten additional units fill at $0.55 for $5.50. The final filled quantity becomes 160, and the canceled remainder becomes 14. Assume confirmed total charges for the acquired position are now $2.20. Purchase spending is $84.50 and all-in cost is $86.70.
The bot must use those actual records even if its earlier local expectation was 150 units. Once the final canceled amount is authoritative, it can release the unused remainder reservation. The separate $20 commitment still exists, so combined actual or reserved amounts are $106.70 under this simplified example, leaving $13.30 below the $120 limit.
An immediate partial-fill order would require different remainder handling. For example, fill-and-kill behavior cancels the unfilled balance automatically rather than leaving it to rest. The adapter should use the actual order type and final result, not treat every partially filled instruction as a persistent commitment requiring the same cancellation sequence.
The incident record should distinguish execution time from receipt time where the interface provides both. A late-arriving notification can describe a fill that happened before cancellation took effect. That evidence should update the account without implying that the venue executed a new trade after a definitive cancellation.
Crypto Prediction Market Bot Recovery Needs Original Attempt Identity
A lost submission response creates uncertainty about the original attempt. The bot should retain its identity, authorization and maximum possible effect while querying the supported account records. A fresh independent order is not equivalent to investigating or safely retrying the existing attempt under the venue's actual semantics.
Recovery should survive a process restart. Before accepting new instructions, the restarted bot needs to reconstruct unresolved attempts, active orders and holdings. A startup routine that simply loads the last displayed balance can miss a commitment created immediately before the crash. Durable account history is part of the risk design.
Different authoritative findings require different next steps. A verified rejection may release reserved capacity. A live order requires monitoring or cancellation. A partial fill changes holdings and may leave a remainder. A completed fill establishes quantity that must be managed through exit or settlement. One generic retry action cannot handle all four correctly.
The related crypto prediction market platform guide evaluates whether the actual venue and account model support the intended workflow. Recovery design should be based on available authoritative records, not on capabilities imagined because they would make the architecture convenient.
Keep Event Determination Separate From Trade Settlement
The trade itself can have a settlement or confirmation process, while the event later determines the claim's payout. These are different stages. An acquired position needs valid account evidence before the bot can manage it, and an eventual event outcome needs its own authoritative determination before final payout accounting.
In the fictional 160-unit holding, an ordinary winning result pays $160 and yields $73.30 against the $86.70 all-in cost, assuming no other costs. A losing result pays zero and loses $86.70. These are the position's branches; the separate $20 reservation belongs to another commitment and should not be inserted into this trade's profit calculation.
If the event becomes observable while account records remain incomplete, preserve both states. The bot can record the expected outcome evidence without inventing a credited payout. Conversely, a confirmed fill remains a real holding even while the source needed to estimate the event is unavailable.
This two-history approach avoids a common operational shortcut: marking everything complete because the event is over. The system still needs to reconcile remaining orders, quantities, charges and the actual account credit. A calendar boundary is not an accounting proof.
Design the Data Record Around Meaning
Store raw observations alongside their interpreted meaning. A price needs its unit, source, outcome convention and time. A quantity needs its allowed precision. A rule mapping needs a version. Derived values such as estimated advantage or reserved capital should identify the inputs that produced them.
Current venue conventions must remain in the adapter. Kalshi's fixed-point documentation illustrates why integer-cent and whole-unit assumptions can become outdated. An adapter should preserve current supported precision and validate actual market constraints rather than normalize away information the account needs for reconciliation.
A source-only model score should not be promoted into a calibrated probability without evidence. Likewise, a market price should not become an objective probability merely because the display uses a percentage sign. The bot's decision record should state what each number means and which uncertainty it carries.
These definitions make errors diagnosable. If a cost estimate differs from the fill ledger, a reviewer can examine units, side conversion, depth and charges separately. Without provenance, the system may only report that two totals disagree, leaving the operator unable to identify the failed assumption.
Test Transitions That Change Money or Quantity
Acceptance tests should exercise a known sequence with independently calculated answers. The fictional 174-unit authorization, 150-unit partial fill and 160-unit final holding provide one such sequence. The expected cost and reservation values should be checked after each transition, not only at the final favorable outcome.
Add tests for a duplicate fill, a missing reference, a changed rule version and an unresolved attempt after restart. The bot should preserve different uncertainty states and apply the appropriate restrictions. A successful test can be a refusal to submit when the required evidence or authority is absent.
Do not confuse simulation with venue validation. A local test can establish that the bot handles the supplied records coherently, but it may not reproduce matching priority, real latency or every exceptional settlement. State the scope and add evidence from supported read-only or appropriately bounded account trials only when actually performed.
The most useful acceptance record can be understood by someone who did not build the system. They should be able to explain what was authorized, what filled and why the next action was permitted. A test that merely checks whether the program repeats its own input fields provides much less assurance.
Test Which History Is Current
Create a trial in which event evidence is fresh but private account records are delayed. The model may produce a new estimate, yet the authorization process cannot safely assume that an earlier order failed or that its reserved capacity is free. The correct response can be to retain the forecast while blocking a new commitment until account reconciliation catches up.
Now reverse the situation. Account records are current and show a known holding, but the designated reference source is stale. The bot can continue recording fills, checking open orders and following an already authorized recovery policy. It should not invent a new event estimate from the absence of data. Current account knowledge does not repair an unavailable forecasting input.
Finally, supply a verified event determination while the payout record is still pending. The event history can advance to its final state, while the account history remains incomplete. New capital allocations should use confirmed available funds, not the expected receipt. These cases demonstrate why one global healthy flag cannot describe the whole workflow accurately.
The interface can remain simple while preserving these distinctions. It can show the current event-evidence state, current account-confidence state and the practical consequence for the next action. The goal is not to expose every internal technical detail. It is to make the reason for observation, abstention or continued reconciliation clear enough that an operator can assess the system's behavior without guessing which history it trusts.
Give the Operator a Specific Uncertainty to Resolve
When automatic recovery cannot establish the state, the operator needs a concise account of the unresolved fact. The alert should identify the affected contract and attempt, the evidence checked, the maximum remaining commitment and the actions blocked. This gives the person a concrete decision instead of a vague request to restart the bot.
Keep event and account alerts distinct. Missing reference evidence can require abstention from new forecasts. Unknown order state can require continued reservation and account investigation. A rule conflict can require contract review. Treating them as one connection problem encourages a generic response that may solve none of them.
Operator actions should leave their own records. If a person authorizes a bounded recovery or changes a mapping, preserve the reason and version. A manual intervention is part of the actual method and should remain visible in later performance and incident review.
A crypto prediction market bot is understandable when its event evidence and account commitments remain coherent through change. The bounded authorization connects them without erasing their differences. That design lets the system observe, abstain, execute and recover with records that explain both what it knew and what it actually caused the account to do.
