I need some tweaks to an existing EA

hello, I'm creating an EA from my own indicator, I would like some changes that I'm not able to make. the work consists of

* create parameter for grid order

*Autolot 1 lot for 10000 (adjustable)

*Closing for a reverse signal as long as the grid orders make at least 100points

*Headging system with multiple lot calculation
