I open contracts, even if it is a small position, and I have principles:
1. Stop loss at most 3%. In fact, I often stop loss at 1-2%. Contracts are gambling. If you don’t find a good time to open and make money, then it is not your market, even if the market starts after the stop loss;
2. Stop loss at most three times a day. After three stop losses, no matter what, I will resolutely not open a single order;
3. Do not open a single order in the oscillation range, and patiently wait for the arrival of the support or resistance level. One is to bet on the bottom, and the other is to bet on a breakthrough;
