Currently, most of the trading teachers in the market are just randomly opening positions at 2650 for short and taking profits at 2600. They only tell you how to place trades without explaining why. If you make a profit, a group of followers will shout, 'The teacher is awesome, the teacher is making money for me.' Most of them are just taking advantage of the channels, and they lack real skills. If a trade goes wrong, everyone starts criticizing. The better strategy groups usually charge fees starting from 10,000. Real experts disdain guiding trades.
