The indicator or EA will show the M pattern with 2 logics on the chart depending on the formation of this M pattern, developer can tell if it can be made into an EA which is my choice "since i don't know coding and if it is possible or not" but if it can't then i can accept an indicator
This indicator depends on bollinger bands only to define the pattern and maybe the zigzag if the developer thinks it will help "further details with the customer"
Developer has to give the source code
