Copytrading Bot — Polymarket

Polymarket copy trading bot development: turn activity into explicit rules

Copy trading needs a precise definition of what to follow. Public activity can show completed trades without revealing a trader's open orders, off-platform hedges or full strategy. The first step is agreeing which wallets, markets and actions the software may use as inputs.

Your rules determine whether a source fill creates an order, whether exits are copied, and how the bot handles an existing position. A source wallet buying an outcome is not permission to buy it at any price. Maximum price deviation, market eligibility and available order-book depth are checked before execution.

Position sizing and market filters

Sizing can use a fixed amount, a configured allocation or a defined proportional rule, subject to account and market limits. We specify rounding, minimum viable order sizes, cash reserves and what happens when several followed wallets signal the same market.

Market filters can restrict categories, liquidity, time to resolution and approved outcome tokens. Resolution timing and changing market metadata matter: the bot must refresh relevant constraints rather than rely on configuration copied once at launch. No trading volume, return or fill rate is guaranteed.

Orders, fills and recovery

The implementation separates observed source activity, intended actions, submitted orders and confirmed fills. Partial fills, rejected orders and timeouts are recorded independently. After a reconnect or process restart, reconciliation compares local records with account state before allowing a new attempt.

Monitoring should expose the source event, applied rule, sizing decision, rejection reason and resulting execution state. This makes it possible to review why a trade was skipped instead of treating every difference from the followed wallet as a software failure.

How we scope and quote your project

Pricing is provided individually after we agree the implementation scope. Multiple source wallets, a custom dashboard, additional deployment environments, backfilling and advanced position management can change the quote. We agree the supported workflows, acceptance scenarios and source-code handover before payment.

Useful inputs are representative wallet addresses, target markets, sizing rules, execution limits and your preferred interface. Use test or restricted credentials during development. Production signing authority and assets remain client-controlled.
