this is my project :
https://fxdreema.com/shared/X51JvcrWd
but Can not read Buffer in costume indicator for rsi divergence
this is my custom indicator:
rsi555+1.mq5

Actually, the positions already exist and then we run the expert
Now, if the new or old position decreases or increases, I need buy and sell volume in each tick

how i can capture the volume of an opened position before running fxdreema EA
