Polymarket · real-time trade feed

Market data,
ahead of the market.

Ahead Tick decodes Polymarket's trade flow at the source and delivers normalized, sequence-verified trade objects over one persistent WebSocket. Your strategy consumes price, size, side and sequence — never raw chain logs.

Protocol

The path a trade takes.

Five stages connect a Polymarket event to a decision in your strategy. The sample interface shows how a captured event becomes a normalized, sequence-verified trade object delivered over WebSocket.

  1. 01

    Event capture

    Polymarket trade events enter one workload-specific ingestion path.

  2. 02

    Trade parsing

    Raw event data becomes a typed trade object with normalized fields.

  3. 03

    Sequence verification

    Observed sequence continuity is checked before the trade is delivered.

  4. 04

    WebSocket delivery

    One stable WebSocket contract carries normalized trade objects.

  5. 05

    Trading strategy

    Your system consumes price, size, side and sequence without raw log decoding.

What you stop maintaining.

  • Raw log decoding. Consume typed trade fields instead of decoding chain event payloads in your hot path.

  • Schema normalization. Price, size, side, market identifiers and provenance arrive in one stable shape.

  • Sequence bookkeeping. Continuity information travels with the feed so missing observations are visible.

  • Payload reshaping. Your strategy receives execution-ready trade objects through one data contract.

  • Market identifiers. Stable market and outcome fields are included with each normalized trade.

  • Provider fan-out. Benchmark one focused feed instead of assembling the critical path from generic RPC responses.

Your strategy is only as fast as its data.
