After browsing a circle of lead traders in copy trading, most of them have been experiencing significant losses these days, and many lead traders basically do not use stop loss. So when a major market movement occurs, they suffer huge losses. After all, nobody can predict when a major market movement will happen, and it's hard to distinguish. Therefore, from now on, no matter what, always set a stop loss of 50 points to prevent losses. It really is unavoidable when hitting the stop loss and then bouncing back; sometimes, not being preventive leads to even greater losses. The frequency of opening positions will decrease a bit in the future, and I will only open a position when there is a very certain signal. Based on my current capital, opening 0.5 lots, with a profit of 30 points is 15u, which is equivalent to a profit of 2% of my capital. Doing this 1-2 times a day is sufficient. So I will patiently wait for the best timing to trade.
