I've read back a little ways on this board and think I see that ya'll are open minded. That said, I like what you've done with this MT4 Renko. And, I like the potential in pound/yen.
I anticipate being more involved on this board (in opinions only -- everyone's gottem, right...lol).
I made one small change here and allowed the user to pick the ATR period instead of being hard coded. Was playing around with the 62 period ATR, but you can change it to whatever you think works best. Also just wanted to point out this support line on the beast in the background.
