ron....I think you suggested it. The renkos are price dependent, and independent of time. The overlays pick off the real-time price, while the renkos only show the filling of the price box..so the real-time price may be higher or lower than what the renko bricks seem to indicate. Since all the indicators are following price, there "appears" to be a non-correlation to the renko bricks.
Frankly, I don't know how to prove that mathematically, but logically, it seems to fit.
Further on the trend attributes of the renkos..when there is a trend change we will be the first to know (grin).....that is, unless we jump the gun by using too small box size, etc.
