Hi Fellas, new member here.

This is great, but the colour change alert doesn't work when the HA is apoplied to a renko chart - the alert comes on when the renko changes colour - the ha changes colour at a different time to the renko.

any way of making one that works with a ha renko?

Here is the latest version from the author.
