ETH 5m Polymarket Backtesting Data
Backtest ETH 5m Polymarket Up/Down strategies with historical order book depth, spreads, realistic fills, and outcomes.
ETH 5m Polymarket backtesting data is designed for short-horizon Ethereum Up/Down strategy research. Because 5-minute markets move quickly, every test should model the order book instead of assuming fills at the displayed probability.
Best Uses
- ETH scalping strategy validation.
- Spread and depth filters for high-frequency decision rules.
- Cross-asset comparison against BTC and SOL short-horizon markets.
- Replay of fast ETH moves and probability reactions.
Execution Checks
For each simulated trade, measure available ask depth for entries, available bid depth for exits, average fill price, spread cost, partial fills, and realized outcome after resolution.
