i dont really think there is a precise number of pips for stop loss and i think the best method is to let the market determine the numbers of stop and target profit for your trades and not have a specific stop but for newbies i will say you should start with having 100 pips stop loss and not less. How point SL depends on the type of trader as if you, if you are a scalper should be determined SL is not too close to your open positions, so as not touched fast .. as well as the type of long term trader, you should set the SL is more than TP that you specify. see also range in price movements trading period you plan .. happy trading
