I've done a fair amount of research with price movement independent of time, albeit not in an automated trading environment. It was also not with Renko bars, although the concept of Renko is something that I think can accomplish that goal of price/time separation.

I think the concept of merging price and time could be fundamentally flawed, but it is used as a basis for almost all modern trading. Any time you force market price to be attached to a time boundary, you have created an artificial representation that could be misleading, or at least misinterpreted. That is my theory anyway.

The combination of Renko + Zorro could open a lot of doors. Price is all that really should matter, but due to limitations in most modern trading software, we don't have a good way to visualize the supply/demand independent of the time constraint.
