How to Build a Polymarket Wallet and Position Tracker
Tracking Polymarket positions, fills and realized exposure with public APIs and on-chain reconciliation.
Tracking Polymarket positions, fills and realized exposure with public APIs and on-chain reconciliation.
Data model
Store wallet, condition, outcome token, average entry, size, realized proceeds and timestamps. Separate orders from fills and settled positions.
Ingestion
Combine Data API activity with CLOB fills and periodic balance reconciliation. Use deterministic trade IDs so reconnects cannot duplicate records.
PnL
Calculate realized and unrealized PnL with explicit mark sources. Include fees, redemptions and transfers rather than relying on wallet balance change.
Alerts
Notify on new positions, concentration, settlement and unexplained balance differences. Avoid exposing wallet credentials in a read-only tracker.
