say I want to calculate some number X derived from each candle. Is there an easy way to take the average of X for Y[user input] number of candles ?

Hi;

I'm not sure I fully got your idea but you can combine the use of Get historical candles to collect the needed candle data with calculation expression block to perform your maths.
I this is what you're looking for ? any concrete example ?

Thanks

Hey Amine , Ill try and give a better example. I need to take the average of a value that I derive from X# of candles that the user defines. Each value to be averages takes the current value and a previous value.

In this example I tried to use a loop with the input being 12 by default. I am (trying to) taking the High-PreviousHigh to get a Difference in the High for each candle in the loop. And then add that to a HighDifference Sum, and then after the loop , divide that by the input value to get an Average of the Difference in the Highs.


Example attached, I doubt it works because it will always recall the same previous candle , instead of the previous candle that would precede the current candle in the array of candles.

Hi,

I see now..
The loop viewer goes through all the candles (12) but the interface will show up only the last value, that's why it is only displaying the last calculation. I need some time to figure out another way to realize your requirement
Beside that there is an error : in the calculation that is plugged at the out of cycle exit(the division) Did you use the "period" as a result on purpose ? cause the the result it generating several errors.

Cheers

The period was unintentional , I must have accidently put it in.

The file uploaded was more of illustrational purposes, trying to ask if loops can call upon a candle and a previous candle to create a value
