I think to prevent the more important call margin is to use the right money management every trader should follow a good money management process such as taking a 2% risk of the total account balance and if the trader trades in this way then this trader will fall in more losses. and I want to say is that one strategy as you say is fine, this is true, but if you will try to apply the strategy at different angles and make more modifications and make more improvements, so this is better than getting more strategy because it makes complex confusion
