2. Assuming that your trading direction is consistent with the market trend, build your position on the basis of the large price difference generated by the previous or subordinate trends, or build your position in a position that is moderately retrograde from the current market trend.
3. Your market-chasing position can form a very favorable change, so you should insist on holding this position. Since the position of chasing the market has changed favorably, you should tolerate any slight trend change, don't trade easily in the day, or try to make a quick profit from contrarian trading.
Once the change direction of your position is favorable, and your technical analysis confirms this favorable trend change, you can increase your position under certain conditions.
Unless the trend analysis shows that the market has reversed and your order is blocked, you should continue to hold positions. At this time, if you are very concerned about the market, you should hedge your original position according to the latest trend. But if you hedge your position, and the subsequent market behavior shows that the main trend still exists, and your hedging behavior is too early, you should completely re-establish your position in line with the main trend.
