Right-side trading is a type of trend-following trading. You only buy after a clear upward trend in price has emerged, for example, when the price of a coin rises from the bottom, breaks through important resistance levels, and shows signs of continuing to rise; only then will right-side traders enter the market. In a price decline, you sell only after the price breaks through important support levels and confirms a downward trend. When a coin starts rising from 50 yuan, and it effectively breaks through the resistance level of 80 yuan, right-side traders will choose to buy. The reason for buying is that it has broken through the resistance level, forming an upward trend; at this time, buying is in line with the trend and belongs to right-side trading. Support levels refer to price points that may encounter support during a price decline, resulting in a halt and stabilization of the price. Resistance levels, also known as pressure levels, refer to price points that may encounter pressure during the upward process, resulting in a price reversal and decline.
