When trading with many pairings, your stop loss may be hit. Each currency has different levels of volatility, which is why the stop loss is usually triggered. As a result, you must investigate each pair in order to choose an appropriate stop loss size. The lower the wicks, the smaller the volatility. The more the volatility, the greater the wicks. So, if you want to be safe, choose a pair with low volatility, such as Bitcoin, which is ideal for scalping.
