In your run_backtest function, make these changes:
|
|
|
|
1. Replace parameter parsing:
|
|
risk_percent, sl_atr_multiplier, tp_atr_multiplier = get_enhanced_parameters(params)
|
|
|
|
2. Replace entry price calculation:
|
|
entry_price = apply_realistic_execution(signal, current_bar['close'], symbol_name)
|
|
|
|
3. Add spread cost deduction after profit calculation:
|
|
spread_cost = calculate_spread_cost(symbol_name, lot_size)
|
|
profit -= spread_cost
|
|
|
|
4. Add spread cost to trade log:
|
|
trades.append({
|
|
'entry_time': str(entry_time),
|
|
'exit_time': str(current_bar['time']),
|
|
'entry': entry_price,
|
|
'exit': exit_price,
|
|
'profit': profit,
|
|
'spread_cost': spread_cost, # New field
|
|
'reason': 'SL/TP',
|
|
'position_type': position_type
|
|
})
