I simply don't like "the open" of the medianrenko - it reperesents the price which is not the actual open price. And if brick is set to odd number (3, 5 etc.), the open will be between the ticks (for example 1000.125 on ES). This is only reason I dropped it and not supporting it.
Other than that, it works as expected.
I am using myself SbSRenko (Side by Side), which is similar to EdsRenko, but Eds Renko does not calculate the volume correctly (at least it did not when I checked it last time).
