Generally speaking: When we encounter significant resistance/support points, we can adopt bottom/top testing techniques.

This approach is quite suitable when the market is moving in a strong uptrend/downtrend but encounters substantial resistance/support...

For example, if the asset touches a historical high again, breaks through but cannot hold... this signals a short opportunity 📶~ However, the overall trend is still strongly upward 👆~

To prevent misjudgment,

My common approach is to follow the trend, gradually reduce positions near historical highs while retaining a core position, and then gradually enter short positions based on the previous highs (it is important to note here that the short position should be roughly equal to the total holding volume of the core position) ~ If the judgment is incorrect... and the market continues to rise, this forms a hedge for the core position, allowing us to minimize trial-and-error costs! Conversely, if the judgment is correct, then we gradually liquidate the original long core position... Similarly, we find the direction of the market with the least cost...

The above method is what I commonly use, shared with those who are fortunate enough to read this! Whether you understand it or not is up to fate, I will not elaborate further! (Not recommended for beginners to try directly)
