@roar, @miro1360, Help EA Panel. (Solved)

[XYON126]

Help with this panel, I need to know about programming, I think, in the photo I indicate what I want to obtain:

Right now the part that I am missing and that I want to solve is that of with a horizontal line drawn from the MT4 platform, take the distance of this line at the current price and press the BUY or SELL button to calculate the minimum lot. I know what can be done but I don't know what blocks and how to do it. Thank you very much and sorry for my English.

@xyon126 Stop complaining about your English, please. It very good! I'm afraid this need a loop to look at the past. Maybe mr roar is available here?
