The secret to trading profits is to be good at losing, make small mistakes, and achieve big wins. When we enter a position and make a mistake, we strictly cut losses and keep the risk of each trade within a small range. When we enter a position and do it right, we hold on to the position, add to the floating profit, and use profits to continuously roll over larger gains, widening the gap between profit and loss. Making one successful trade can offset many losing trades, achieving a process of big wins and small losses, ultimately resulting in a positive return.
