How to get/store specific candle info?
You do it exactly what you said
static double saveHigh; if( Low[...] > MathMax( EMA(2), EMA(10) )) saveHigh = High[...];
Thank you so much. However, what if another true event occurred later, would this update this "static double saveHigh" with the new value?
I will include your code and see
I am trying to check for a change in the signal as you taught me before not a signal itself. So, if before was no signal but now ---> true signal.
Others ( true->true) or (true ->false), will be false signal. Then i capture this Low or High value in a static variable.
I will be able to do that, this would be awesome. This concept with work for me with many other situations.
I will update here.
Thx
Unfortunately, i still can not comprehend or able to code the code correct
and here is all the code:

However, i am not sure if this whole if statememts are doing what i need }
I feel i am close but still not correct
if ( iHigh("",0,1) |

Hi, i have a question regarding getting/storing the candle info on which a specific event happened.
let me explain, suppose i am looking for the candle that has the following condition:
Low > EMA(2) && Low > EMA(10)
then, i would like to store the HIGH value data of this specific candle (say 1.5000) for later on calculation.
with getting newer candles, i still need to keep this value not changed. How could i do this?
Should i fetch backward with every new candle formation to get this information everytime candle forms. Or how?
Thanks
