MakarFX:
Wrong, it needs the time of the previous candle

Well, you can also telepathize the zero candle :) because it is the last one, not the previous one.

If we do psychic analysis we can suppose that we are looking for the value inside one hour candlestick, which brings us back to my previous post about iLowest and iHighest.

ANDREY:

Thank you.

PapaYozh was right, because according to your condition

if (Bid - iLow( NULL ,PERIOD_H1,1)>=0.0030)

you're not looking for a low, you're looking for a pullback from a low.

[Tretyakov Rostyslav]

PapaYozh:

Yes, I wasn't paying attention.

I wasn't paying attention...

[Valeriy Yastremskiy]

Vladislav Andruschenko:

just leave it?

Well just checked. it's not executing in mt5. build flatt 2940

Or have you removed OnCalculate?

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa :-) created a script and put it in the indicators folder

Unique.

More like an exception, you just stuck the script in the indicators folder and the terminal gobbled it up.

Yeah, that's the trick/problem... Confused folders at first, then took it as a feature... A good feature, one time execution after oninit.

Valeriy Yastremskiy:

Yes, that's the trick/problem... Got the folders confused at first, then took it as a feature... A good feature, one time execution after oninit.

So it's just a script that executes in the chart thread.

Makar, you gave a link to an indicator with an answer to my question. Nothing works( I did it by gut feeling, I don't have the brains for it. I need your help!

MakarFX:

I tried to get a picture like that.

[ifitstrue]

It turns out like this.

[Tretyakov Rostyslav]

ifitstrue:

It goes like this.

If you want the previous day, see the previous post,

and if it's the current day, correct it.

      ma_buffer_high[i]=iMA(Symbol(), prd, PeriodMaHigh, 0, MethodMa, PriceMaH, index);
      ma_buffer_low[i] =iMA(Symbol(), prd, PeriodMaLow, 0, MethodMa, PriceMaL, index);
