yes we can not judge the stop loss with the numbers we set, it may depend on the chart situation and the support and resistance levels, but I want to tell you that always placing sl and tp without your trademark will be risky, because I have lost my account with do not install sl, you can also use 50 pips for sl. and I think the safe amount of pips to set sl depends on the pair and the market where we trade ... in london market and newyork usually higher volatility, stop loss should be bigger .... asia and australia are to flatter so stop lose is not too big ... but it also depends on your type, is it swing or scalper ...
