Use a structural stop
The stop should reflect thesis invalidation, not a number selected only to improve the ratio.
Enter the exact entry, stop, target, quantity and your own cost estimate to see a cost-adjusted reward-to-risk ratio and mathematical break-even win rate.
This calculator uses your estimates and does not predict target probability or guarantee stop execution. Actual charges, spread, slippage and gaps can differ.
The stop should reflect thesis invalidation, not a number selected only to improve the ratio.
Potential reward should come from market structure and the intended holding period.
Spread, slippage, brokerage and taxes reduce realised reward and can increase loss.
The planned ratio does not show target probability; track average realised gains and losses.
The output is educational decision math. It does not estimate the probability of success and cannot include every charge, gap, liquidity condition or execution outcome.
