#合约事件 is really great, looking at the time, easily earning over 100 U, today I decided to take the profit.

Let me share the strategy with you.

First: Watch the short line for 15 minutes and invest at the highest or lowest point.

Second: Wait for the pin insertion, this is the most stable.

Third: If you don't look at the first two, just invest like this.

5, 5, 10, invest like this; if you miss a few in a row, stop, calm down, today is not suitable for you to play.
