From 533a00dce7553cc56969dc8d82d914d7456c44eb Mon Sep 17 00:00:00 2001 From: rob Date: Sun, 15 Mar 2026 16:49:18 -0300 Subject: [PATCH] Fix backtest performance: cache compilation and skip unnecessary DB writes Performance optimizations for backtesting: - Cache compiled strategy code instead of recompiling every iteration - Skip save_context() for backtests (no DB persistence needed per tick) - Check cache existence before recreating broker state caches - Add margin position processing to backtest strategy These fixes eliminate O(n) slowdown that caused backtests to progressively slow to a crawl. Backtests now maintain consistent speed throughout.
