Help, percentile rank.

Andres452 2020.06.13 05:57

Greetings friends.

I've been through the forum and can't find a percentile rank indicator for metatrader 4 (mql4) and I have no idea how to code it either since I'm new to mql4, I come from tradingview and there I have a rank indicator percentile in pine script, which is the tradingview programming language and it has a function called percentrank, but I can't find any similar function or indicator in metatrader4 (mql4) that shows only the percentile range, I would be very grateful if you help me to code it or give me an idea of how to do it, I attach a tradingview image showing the function I am talking about in the pine script.

Thank you.

Help you with what? You haven't stated a problem, you stated a want. You have only four choices:
1. Search for it. Do you expect us to do your research for you?
2. Beg at:
3. MT4: Learn to code it.
  MT5: Begin learning to code it.
  If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into yours.
4. or pay (Freelance) someone to code it.

We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using CODE button) and state the nature of your problem.

Thanks for your help, this is my code, the result must be between 0 and 100 but for some reason the result is a negative value, you know why ?

Actually what I'm looking to graph is a line with this formula: PercentRank1(iATR(17),23) where 23 is the number of the historical bars.

Andres452: the result must be between 0 and 100 but for some reason the result is a negative value, you know why ?

 ATRBuffer[i] = PercentRank1(iATR(NULL,0,17,i),23)

Prices are 1.2345º. ATR is 0.00xxx. You will never find an ATR in the range of prices.

So, I don't understand why in tradingview pinescript if it works, and the formula is exactly the same, the calculation results are between 0 and 100.

Can you post a screenshot with the expected result (from tradingview ) ?

Alain Verleyen : ¿Puedes publicar una captura de pantalla con el resultado esperado?

Yes. It just needs to be coded, perfectly and easily doable with mql4.

Andres452 2020.06.13 19:21 #10

Alain Verleyen : Si. Solo necesita ser codificado, perfecta y fácilmente factible con mql4.

I think I already have it coded, but for some reason my code throws negative results, do you know what it could be ?
