Hoooo, now because of trying to make a good question I think I found the solution, maybe I just have to count the share of last day, and considering this number like zero for today, I will try to program this after, if you have other solution?

@robertogozzi tks for the Flag tips,

Do you have a link from the forum with a very complex flag method, it will perhaps allow me to appropriate the method

Do you use a specific software for the analysis ?

I realize now that my programming problem with ProRealTime is due to the analysis of what I want to do, I am very good in analysis, but how to put an analysis on paper, I had learned the method of patatoide I think long time ago (potatoide, I don’t know how to say it in english)

tks you for the solution, I found a solution just before your answer, and I thank you very much for the effort you make to formulate such precise answers,

for quality answers, you are very strong or I am very weak, in any case you are stronger,

I tested your solution, it makes me buy 2 times in A and 2 times in B, my solution suits me and makes me buy once in C and D, I wil try to understand and use also your solution
