@roar I did that but receiving errors when I compile the file for checking !
is it possible to have it as a regular block in which variable windows are set as the gird block? https://fxdreema.com/shared/SVqtuJC6
the grid block with 3 pending as Buy stop and the required loop to generate 13 pending as Buy limit, with distance 20 pips space between lines, no TP/SL.
Variables are adjustable through Expert properties window in back testing tool.

Thank you roar for your help. where can I put my loop variables?
Initial lot size
Increment size
No. of pending orders
Offset from price
Distance between orders.
Appreciate further explanation. thank you.

Thank you for your time. How to contact mr roar please?

Its simply to add a fixed amount (+ X lot) for every next gird line. say grid initial lot size 0.1 and we need the (X lot) = 0.2, then we'll have:
1st line = 0.1 ,
2nd line = 1st line + 0.2,
3rd line = (2nd line) +0.2,
4th line (3rd line ) + 0.2,, etc.
I think random (manually put the size) will serve better, but its ok with the easier in programming.
Appreciate your support.

Thank you for the answer, but with this % we can't put 1,2,3,4,5, if 200% will get 1,2,4,8,16. I'm looking for how to add certain amount of increment (order lot size + X for the next one). is it possible ?

I need help with how to set ascending lot sizes in a grid pending orders. if I start with 0.01 and want to increase by 0.01 for every next order. thank you.
