People like to call them stop runs, but in reality they are just poorly placed stops that are inside the noise.
If someone has not bothered to learn to trade, whether they use stops or where they are placed becomes irrelevant.
I know what you are trying to get at here and I think the spirit is correct. However, one has not learned to trade successfully unless one has learned proper stop placement. This can be done only through clinical experience and not back testing.
Put stop loss placement is ned to learned, but also learn to determine exit point I think also not less important because exit point wil determine last order wil get profit or loss, and tis is also required good skill to analyze the market to determine best timing exit point
I wouldn't dream of trading without stops. On most trades there is a point where the theory behind my entry is no longer valid and it is at that point i want out. If I perceive that many others will have their stops right there I might adjust the price some but conceptually every trade has a rational and if that rational ceases to exist I'm out.
Still many tarder using stop loss, I am also still use stop loss in my trades, sometime I am modify stop loss if already get in floating profit and I can modify stop loss in profit, with expectation if trend will continue will get maximum profit
