ASI index has strong practical significance, and the signal is clear and accurate. If there is only one ASI indicator line in the software you use, it is suggested that you check whether there is a parameter of N-means of the second line (ASI) in the parameters. If so, you can change the default parameter to 6. You can use it. If not, you can add an average by yourself. There is no front high line in asi indicator. You have to use the mouse to compare whether today's asi value has crossed the previous high point. The third question is meaningless. As long as you use numerical values to confirm that today's ASI value has exceeded the previous high point, ASI indicators can be more practical than any indicators in use such as KD, RSI and MACD. Note that it is also a golden cross, but it is different because of the difference between the numerical value and the positive and negative number.
