The best defensive trading strategy is stop loss I think you can also consider and take profit at the same time in this way if the price pumps and dumps just like a trap at the resistance you have the chance to take profit to it unlike if you don't have take profit also then you miss the chance on having a profit.
stoplos tool is very helpful for traders to cut losses automatically. especially if we can not monitor the market continuously. With high volatility, of course, we have to be vigilant, when the price leaves our work area, at the bottom of the support, we put a stop loss which will save us from bigger losses.
