I am sick of reading all the nonsense that you want to check every second, but it is not "once every 20 seconds" - Expert Advisors and Automated Trading

Hello, Valery! I completely agree with you. To write a correct code, you need an exact condition for opening a position. This code works too:

but the whole question is whether it should work as Vitaly intended? Frankly speaking, I don't quite understand why once every 20 seconds (or even once every 10, 5 or 1 second), we need to check the price difference. What will it do in terms of determining the direction of further price movement?

Regards, Vladimir.

You describe the task incorrectly! It is not "once every 20 seconds", but to check every second with the indicators that have passed some time ago. As for "why" - this is not a question for this discussion. (And 20 seconds is just as an example).

It's like a moving average, where the first candle is compared to the second candle. Only I have to calculate everything inside the current (zero) minute candle. (Or even better - on a line chart. After all, 20 seconds can flow to the first candle).

Yes, my mistake, I didn't fully understand what you want to do/check.

But if the distance equal to your constant is travelled not in any even number of seconds, but for example in 10.964 seconds or 11.283 seconds, what happens then? Will the condition be fulfilled or not?

In the term "comparison with a constant" I do not mean equality, but "more" "less". In case of positive difference we compare with the constant with + sign, and in case of negative difference we compare with the constant with " - " sign. If in the first case we exceed the constant, we buy. In the second case, if the value is less - sale.

I am so sick of reading all this nonsense... After all, the code is only FOUR lines, and the discussions are 3 pages long.

  MqlTick mqlTick[], symbTick; // объявили переменные
  SymbolInfoTick(_Symbol, symbTick); // это последний тик
  CopyTicksRange(_Symbol, mqlTick, COPY_TICKS_ALL, symbTick.time_msc, symbTick.time_msc-20000); // Получили все тики за последние 20 секунд
  double delta = NormalizeDouble(mqlTick[ArraySize(mqlTick)-1].bid-mqlTick[0].bid, _Digits); // получили разницу крайних значений массива

20,000 milliseconds is 20 seconds.

Next, put a condition on the size of the delta variable more/smaller, left/right or north/yuh....

Alexey Viktorov is a snob, but realised the trick at once. 😆

P.S. The only thing I can recommend is to watch my message here for the sake of interest. And then look how the price behaved after this message. It rolled back to 0.98000, or more precisely to 0.9806, and then went up again, as shown by the red arrow on the screenshot of the price chart. This recommendation is just for your reflection.

Vitaly, you don't know a person, but you are already trying to judge him. It's very incorrect of you. Every man has his own principles. That's it, end of story!

With respect, Vladimir.
