There is no delay at all, but the price (or candlestick) itself.

Index, a statistical term, is a combination of the concept and its numerical value describing the quantitative characteristics of the "population". The essence of indicators is induction and statistics.
No matter what standard is used for induction and statistics, only "total" can be displayed, and "individual" is ignored.
There is no need to discuss these concepts.

What I want to say is: For example, XU v3-VQ 2 of master xard777 is undoubtedly a very good indicator, but due to too many signals, some signals are inevitably unprofitable (these signals themselves are not wrong! Just because Transaction costs are not profitable), so the signal needs to be reduced.

The method of reducing the signal is another problem.
