suffering losses is better than having a margin call. and one thing that can prevent us from margin calls is money management. This basic rule is actually what will save most of our accounts. you don't believe me in fact, most traders lose because they trade more. and lol, same with many of my experiences. sometimes hoping the price of getting a retrace can make us suffer even greater losses. we must avoid thinking like this. Hope is not a logical way to get involved in our trade. that's why you should always use SL in every position.
