So you want to create a cool custom indicator, but you're not a programmer, eh? Post your idea in Indicators Forum; i'll try to brew one for you at no cost! Provided that it ain't 10-line fancy indicator that looks like a colorful rainbow, and you can wait a day or two, of course.
Just post your idea first mate and see if we can work out. Request an indicator now at https://www.mql5.com/en/forum
I cannot code or modify any indicator for you now, because I don't have the time at the moment. You could post your request in this forum, and i'll be taking a look at them starting from oldest requests when i'm free, hopefully by next week.
Happy trading to you all,
