Summary Formulas
- Risk per Trade = Balance ร Risk%
- Structural Stop (long) = key โ buffer; (short) = key + buffer
- ATR Stop (long) = entry โ (ATR ร trailMult); (short) = entry + (ATR ร trailMult)
- Chosen Stop = tighter (closer to entry)
- Risk/Share = |entry โ stop|
- Raw Shares = riskPerTrade รท riskPerShare
- Cash Cap Shares = cashCap รท entry
- Final Shares = min(raw, cap) (rounded if no fractional)
- Gross R:R = profitPerShare รท riskPerShare
- Net Profit โ ( (profitPerShare โ 2ยทslip)ยทshares โ 2ยทcomm )
- Net Loss โ ( (riskPerShare + 2ยทslip)ยทshares + 2ยทcomm )
- Net R:R = NetProfit / NetLoss
