Doing T in a semi-warehouse can better control risks, and you can enter and retreat. Of course, the income may be less than that of Man Cang, but the trading mentality and pressure will be much easier.

To do T, you should know the trend, that is, to do multi-direction (that is, buy first and then sell) or short direction (sell first and then buy), otherwise it will be easy to fly. Personally, I think the former is easier to do. If you are not sure about the direction, you would rather not do it that day.
