Oh,The problem has been corrected. There should be no problem.

@seb-0 oh,But how can I compare the price between A and B? I mean:A price>B price. or B price > A price

Thank you. The setting of variables here is very interesting. These are very enlightening.

I see what you mean. I'd like to come up with some ideas about the effective period and the cancellation of settings later.

I want to implement a process to compare the prices of a and B, in order to take some action when condition C passes.

Please help. It may be a very simple question. I'm sorry I didn't succeed.

These three candles don't need to be continuous, just happen in a period of time, such as 4 hours. Because I don't need it to be continuous.

Thanks in advance！

@nillav This looks accurate. Let me try,：）

@ambrogio Oh, I use control point. This may be a problem, I'll try, thank you!

@nillav Salute! Thank you so much. Let me study it. Although there are not many people in this forum, it's really warm-hearted.

@l-andorrà oh , it's a backtesting

@nillav I try to understand what you said, but I'm not a programmer, so it's a bit hard. Do you have a similar example to show me? I can try it myself.：）

@l-andorrà All of my screen shots were taken on the same 15 minute chart. There is no switching cycle. In addition, the option is "close price". I think it should be the value read after the completion of the Bar. This value should not be changed, right?
