Good indictor but it would be nice if you can change a 2d candle to red that will help out a lot other than that good job.

I had to reinstall my mt4, how do I add the purchased indicator back on the newly installed app?

Hello, You just need to be logged into MQL within the new MT4 install, using the same account you used to purchase the indicator, and it will be available in the usual place.

Hope that helps.
