 **Takeaway**: Always validate business logic after performance optimizations, even if they seem unrelated.
 
+### ❌ **Pitfall: RSI Indicator Optimizations**
+**What happened**: Attempting to optimize the RSI divergence indicator decreased performance by ~50%!
+- Changed from **6446 candles/sec** back to **2797 candles/sec**
+- **Complex LINQ optimizations** like `OrderByDescending().Take()` were slower than simple `TakeLast()`
+- **Creating HashSet<Candle>** objects in signal generation added overhead
+- **Caching calculations** added complexity without benefit
+
+**Takeaway**: Not all code is worth optimizing. Some algorithms are already efficient enough, and micro-optimizations can hurt more than help. Always measure the impact before committing complex changes.
+
+## Performance Bottleneck Analysis (Latest Findings)
+
+Recent performance logging revealed the **true bottleneck** in backtest execution:
+
+### 📊 **Backtest Timing Breakdown**
+- **Total execution time**: ~1.4-1.6 seconds for 5760 candles
+- **TradingBotBase.Run() calls**: 5,760 total (~87ms combined, 0.015ms average per call)
+- **Unaccounted time**: ~1.3-1.5 seconds (94% of total execution time!)
+
+### 🎯 **Identified Bottlenecks** (in order of impact)
+1. **TradingBox.GetSignal()** - Indicator calculations (called ~1,932 times, ~0.99ms per call average)
+2. **BacktestExecutor loop overhead** - HashSet operations, memory allocations
+3. **Signal update frequency** - Even with 66.5% efficiency, remaining updates are expensive
+4. **Memory management** - GC pressure from frequent allocations
+
+### 🚀 **Next Optimization Targets**
+1. **Optimize indicator calculations** - RSI divergence processing is the biggest bottleneck
+2. **Reduce HashSet allocations** - Pre-allocate or reuse collections
+3. **Optimize signal update logic** - Further reduce unnecessary updates
+4. **Memory pooling** - Reuse objects to reduce GC pressure
+
+## Major Optimization Success: Pre-Calculated Signals
+
+### ✅ **Optimization: Pre-Calculated Signals**
+**What was implemented**: Pre-calculated all signals once upfront instead of calling `TradingBox.GetSignal()` ~1,932 times during backtest execution.
+
+**Technical Details**:
+- Added `PreCalculateAllSignals()` method in `BacktestExecutor.cs`
+- Pre-calculates signals for all candles using rolling window logic
+- Modified `TradingBotBase.UpdateSignals()` to support pre-calculated signal lookup
+- Updated backtest loop to use O(1) signal lookups instead of expensive calculations
+
+**Performance Impact** (Average of 3 runs):
+- **Processing Rate**: 2,800 → **~5,800 candles/sec** (2.1x improvement!)
+- **Execution Time**: 1.4-1.6s → **~1.0s** (35-50% faster!)
+- **Signal Update Time**: ~1,417ms → **Eliminated** (no more repeated calculations)
+- **Consistent Results**: 5,217 - 6,871 candles/sec range (expected system variance)
+
+**Business Logic Validation**:
+- ✅ All validation tests passed
+- ✅ Final PnL matches baseline (±0)
+- ✅ Two-scenarios test includes baseline assertions for consistency over time (with proper win rate percentage handling)
+- ✅ Live trading functionality preserved (no changes to live trading code)
+
+**Takeaway**: The biggest performance gains come from eliminating redundant calculations. Pre-calculating expensive operations once upfront is far more effective than micro-optimizations.
