When the price reached a certain price, the original trend did not continue, not only did it not continue, but it also turned around and the trend direction changed. Looking back, this position is a support level and a pressure level, but there is no breakthrough.

Why are these positions effective? Because when I went to these positions before, the price began to turn around, indicating that most people think that the price of such positions is almost over, forming a * * * understanding. Since there was * * * knowledge about this before, when prices reach these positions again, such * * * knowledge may still exist, that is, the role of support and pressure may still appear, which is why some prices in futures have the role of support and pressure.
