There are still some functions. Any support level and resistance level are only people's own psychological resistance and support, but once they become the majority of psychological support and resistance, many people will make a profit or stop loss in this position, so it still plays a certain role.

Take OK's bitcoin transaction as an example, or gold foreign exchange transaction as an example. First, set the 200-day moving average in the market analysis interface.

The price is above or below the 200 line, and the 200 line in the afternoon is attractive to the price. It will be realized from 3: 05 to 15, and it will be gradually realized on the 30-minute 1 hour chart. In this case, we can build positions for the rebound, which is more profitable.

When the price hits the 200-day moving average for the first time, it will rebound quickly. You can open positions here and generally make money every second. The longer the time period, the greater the profit. For example, if the price rebounds on the 200-day line in 4 hours, the income will be greater than the 200-day line in 30 minutes. In addition, it should be noted that this method of opening positions is to open positions against the trend. Generally, you can't hit and run, but run if you make money.
