Strategy: Polymarket · Probability Momentum
When to use
Use this when someone asks for momentum, trend following, breakout, follow-the-crowd behavior, fast-moving crypto milestones, or rapid probability acceleration.
What the agent should look for
- Exact market slug from
POST /v3/markets/search. backtestSupported: true.- Sufficient filled-trade history for the requested lookback window.
- Rising probability on last-trade filled ticks.
- Elevated fill counts or larger notional during the move.
- Market not too close to resolution unless user explicitly accepts expiry risk.
Backtest fit with filled data
Good fit for this archetype. Filled TradeTick history can validate whether momentum would have produced fill-driven entries, exits, and directional exposure.
Limit: filled-trade backtests do not prove maker queue position, maker rebates, or order-book depth. Treat this as taker-style behavior evidence, not certainty.
Strategy logic
Enter YES when recent probability rises more than a threshold over lookback_ticks. Exit when exit_after_ticks is reached, or when momentum stalls if an exit condition is included.
Nautilus strategy shape
subscribe_trade_ticks(instrument_id)to stream TradeTicks.- Use
on_trade_tickas the main event handler. - Submit market or conservative IOC orders.
- Track open position and fill state in
on_order_filled.
Example strategyConfig
{
"lookback_ticks": 5,
"momentum_threshold": 0.02,
"order_size": 10,
"exit_after_ticks": 25,
"max_entries": 3
}
Iteration knobs
| Knob | Effect |
|---|---|
lookback_ticks |
Larger values reduce noise; smaller values react faster. |
momentum_threshold |
Higher values reduce frequency and require stronger momentum. |
order_size |
Larger values increase PnL sensitivity and liquidity exposure. |
exit_after_ticks |
Shorter values trim quickly; longer values hold trend. |
max_entries |
Caps repeated entries in choppy markets. |
Failure modes
- One large fill can produce a false momentum signal.
- Thin trades can overstate available liquidity.
- Late-resolution markets can reverse from mark-to-market gains to a 0/1 close.
- Stale fills can make momentum look cleaner than it was live.
User-facing framing
"This is a probability momentum strategy: it buys when fills and last-trade probability move together in one direction. It is backtestable with filled TradeTicks, but it does not confirm maker queue priority or spread capture."
