Build a simple EA/Script for me on MT4

My requirement is simple ~ Not based on any indicator but based on price(Open Buystop) OR  (Open Sell Stop) with TP + SL obviously.  Once order is executed, cancel the other order. Has a few If/Then conditions but it can be easy if you have already developed EAs on MT4 earlier. Reach out to me only if you have already developed Expert Advisors before
