- Old calculation: (closePrice - entryPrice) * sizeInBaseAsset = tiny P&L in dollars - New calculation: profitPercent * leverage * notionalUSD / 100 = correct leveraged P&L - Example: -0.13% price move * 10x leverage * $540 notional = -$7.02 (not -$0.38) - Fixes trades showing -$0.10 to -$0.77 losses when they should be -$5 to -$40 - Applied to both DRY_RUN and real execution paths
