Start Practicing FreeMost trading simulators replay old market data. The problem? You can accidentally memorize patterns, and the fills are instant and unrealistic. PatternFoundry generates fresh market sessions using an agent-based tick engine with a real simulated order book. Every session is unique. Fills include spread, slippage, and queue priority.
