+# Backtester Caveats & Limitations
+
+## What We've Built
+A backtesting system integrated into the main bot that:
+- Reads historical liquidations from the live database (`liquidations.db`)
+- Fetches historical 1-minute candles from Binance API
+- Simulates the bot's trading logic with configurable parameters
+- Writes results to a separate database (`backtest.db`)
+- Provides a UI to configure and run backtests with expandable trade details
+
+---
+
+## Known Caveats
+
+### 1. **Entry Price Approximation** ⚠️ MAJOR
+**Issue**: We enter at the **next candle's open** after a liquidation event.
+- Real bot executes immediately at market price when liquidation happens
+- Backtest waits for next 1-minute candle to open
+- **Impact**: Could be off by several ticks to significant slippage in volatile moves
+
+**Status**: **CAN'T FIX** - We don't have tick-by-tick order book data. We apply slippage estimation (8 bps default) but it's still an approximation.
+
+---
+
+### 2. **TP/SL Resolution Within Candle** ⚠️ MODERATE
+**Issue**: When both TP and SL are hit in the same candle, we don't know which hit first.
+- Using `tiePolicy: 'worst'` (assumes SL hit first) as default
+- Real outcome depends on intra-candle price action we can't see
+
+**Status**: **PARTIALLY ADDRESSABLE** - Could fetch tick data or use smaller timeframes (5s candles if available), but 1-minute is Binance's smallest public interval for futures.
+
+**Current mitigation**: Configurable `tiePolicy` parameter ('worst', 'best', 'dir')
+
+---
+
+### 3. **VWAP Protection Not Implemented Yet** ⚠️ MODERATE
+**Issue**: UI has VWAP protection settings but the engine doesn't calculate or apply VWAP filtering.
+- Settings are captured but ignored in backtest execution
+- Real bot would block trades against VWAP trend
+
+**Status**: **CAN FIX** - Need to:
+1. Calculate VWAP from candle data (typical price × volume)
+2. Compare entry price to VWAP
+3. Block LONG if price > VWAP, block SHORT if price < VWAP
+
+**TODO**: Implement VWAP calculation in `engine.ts`
+
+---
+
+### 4. **Threshold System Edge Cases** ⚠️ MINOR
+**Issue**: Multiple liquidations at the exact same millisecond timestamp.
+- Real bot might process them sequentially with sub-millisecond gaps
+- Backtest processes them in array order (database sort order)
+- Could trigger multiple entries if cooldown hasn't expired
+
+**Status**: **INTENTIONAL** - We're not deduplicating data. If the bot's logic (cooldown, threshold window) would allow it, we simulate it.
+
+**Note**: The 60-second threshold system should naturally aggregate these anyway.
+
+---
+
+### 5. **Funding Fees Not Simulated** ⚠️ MINOR
+**Issue**: Positions held across funding intervals (8-hour cycles) incur funding fees.
+- Not calculated in backtest P&L
+- Real trading would have these costs
+
+**Status**: **CAN FIX** - Could add funding rate calculation:
+1. Track position hold time
+2. Apply funding rate at 00:00, 08:00, 16:00 UTC
+3. Fetch historical funding rates from Binance
+
+**Impact**: Generally small for positions held < 8 hours, but compounds for longer holds.
+
+---
+
+### 6. **Market Impact / Order Book Depth** ⚠️ MINOR
+**Issue**: We assume infinite liquidity at the entry/exit price.
+- Large orders would move the market
+- Real bot uses limit orders that might not fill immediately
+
+**Status**: **CAN'T FIX** - Would need historical order book snapshots. We use slippage estimation instead (8 bps default).
+
+---
+
+### 7. **Exchange Latency & Race Conditions** ⚠️ MINOR
+**Issue**: Real trading has network latency, order queue delays, rate limits.
+- Backtest assumes instant execution
+- Multiple traders might be reacting to the same liquidation
+
+**Status**: **CAN'T FIX** - Inherent limitation of backtesting. Slippage parameter accounts for some of this.
+
+---
+
+### 8. **Limited Historical Data** ℹ️ INFO
+**Issue**: Liquidations table only has data from when the bot started recording.
+- Can't backtest periods before bot was live
+- User gets warning for 3-month and 1-year backtests
+
+**Status**: **CAN'T FIX** - Historical liquidation data not publicly available in detail. Binance only provides aggregated liquidation orders, not the raw feed.
+
+---
+
+### 9. **DCA Entry Timing** ⚠️ MINOR
+**Issue**: Each liquidation above threshold triggers a DCA entry at next candle open.
+- Real bot might batch multiple liquidations or skip some due to rate limits
+- Backtest processes every qualifying liquidation
+
+**Status**: **MATCHES EXPECTED BEHAVIOR** - This is how the bot should work. If it's too aggressive, adjust threshold or cooldown settings.
+
+---
+
+### 10. **No Live Bot State Conflicts** ✅ SAFE
+**Issue**: N/A - Backtester is fully isolated.
+- Reads from `liquidations.db` (read-only)
+- Writes to `backtest.db` (separate file)
+- No risk of interfering with live trading
+
+**Status**: **WORKING AS DESIGNED** - This was a critical safety requirement and it's properly implemented.
+
+---
+
+## Recommendations
+
+### For Most Accurate Results:
+1. ✅ Use **"worst" tie policy** (default) for conservative estimates
+2. ✅ Enable **60-second threshold system** to match live bot behavior
+3. ✅ Set **realistic slippage** (8-10 bps for liquid pairs, higher for low liquidity)
+4. ✅ Test on **recent data** (last 1-2 weeks) where liquidation patterns are most relevant
+5. ⚠️ **Implement VWAP protection** if you use it in live trading
+6. ⚠️ **Add funding fees** for multi-day backtests
+
+### What to Trust:
+- ✅ **Trade frequency** - Good estimate of how often bot triggers
+- ✅ **Win rate** - Directional accuracy (TP vs SL hit rate)
+- ✅ **Relative performance** - Comparing different parameter sets
+- ⚠️ **Absolute P&L** - Ballpark only, real results will vary by 10-30%
+
+### What NOT to Trust:
+- ❌ **Exact P&L down to the cent** - Too many unknowns
+- ❌ **Extreme market conditions** - Flash crashes, liquidation cascades behave differently live
+- ❌ **Very short timeframes** (< 1 day) - Not enough data points
+
+---
+
+## Next Steps to Improve
+
+### High Priority:
+1. **Implement VWAP filtering** - Critical if you use it live
+2. **Add funding fees** - For multi-day backtests
+3. **Calculate Sharpe ratio & max drawdown** - Better risk metrics
+
+### Medium Priority:
+4. **Add commission tiers** - VIP levels have different fees
+5. **Simulate partial fills** - More realistic for large orders
+6. **Add slippage variance** - Not always 8 bps, varies with volatility
+
+### Low Priority:
+7. **Fetch 5-second candles** (if Binance adds them) - Better TP/SL resolution
+8. **Add position liquidation simulation** - If leverage is too high
+9. **Monte Carlo analysis** - Run same backtest with random variation
+
+---
+
+## Bottom Line
+
+The backtester is a **useful optimization tool** for:
+- Finding profitable parameter ranges
+- Understanding trade frequency and patterns  
+- Comparing strategy variations
+- Identifying obvious losers before risking real money
+
+But it's **NOT a crystal ball**. Real trading will differ due to:
+- Execution timing
+- Market microstructure
+- Exchange infrastructure
+- Other market participants
+
+**Use it to guide decisions, not as gospel.**
