vitaliy zamkovoy current price and compare it to some constant with the subsequent opening of an order, how should we record it?

Copy the ticks for the last 20 seconds, get the difference of the extreme values of the array and compare it with that constant.

This should not be done one time, but as a continuous EA loop.

(A piece of code if you can...).

Good morning, Alexey! What if we initialise the timer for 20 seconds first and check the difference of extreme values without an array? Isn't this option easier?

Regards, Vladimir.

This is all very interesting, of course, but I would like to see a "cheat sheet" for a coloniser 😁

It's too early to talk about the cheat sheet. I'm learning programming myself, that's why I'm asking questions. Maybe it will come in handy for me someday too.

Regards, Vladimir.

It may be easier, but the task is not to check every 20 seconds, but every tick from the current price 20 seconds backwards.

This should be done not once, but as a continuous cycle of the Expert Advisor.

(A piece of code, if you can...)

In OnTick it will be executed every tick continuously.

A piece of code if you can, but it goes against my principles. I don't write cheat sheets for two-liners. One cheat sheet for all cases has already been written and can be found here.

I will now ask for help from knowledgeable people again, but please don't get distracted by me - keep the principles!
 
If we subtract the price of twenty seconds ago from the current price and compare it with a certain constant for the subsequent opening of an order, how can this be written in the Expert Advisor?

ok. Please wait for a reply.
