Where a stop actually belongs
Risk & Position Sizing
At the point the idea is wrong
A stop-loss belongs at the price where your trade idea is proven wrong: a broken swing point, the far side of an order block, past a sweep's extreme. Never at a random, convenient round number.
Too tight invites noise
A stop that's too tight, sitting inside normal noise, gets triggered by everyday wiggles that have nothing to do with the trade actually being wrong.
Wider needs smaller size
A stop that's too wide just to give it room, without adjusting size down accordingly, turns a normal loss into an oversized one. Width and size are a package deal.
