The best risk process is the one you can execute under stress because it was defined in advance.
Ask what market condition would make the strategy wrong, how much damage is acceptable, and whether the live environment can surface those signals quickly.
Define the drawdown, technical failure, or behavior drift that ends the strategy's right to keep trading.
Even good systems fail. Capital allocation should assume uncertainty rather than reward confidence.
When evidence says the system no longer fits its environment or its risk budget, close it. Replacement beats denial.
A trailing stop ratchets up as price rises and only ever moves in your favour. Set the trail distance and see where it would have locked in the move on this sample path.
Do not let recent outcomes rewrite your risk standards.
