I remember looking at and playing with an indicator here on FXcodebase some time ago that was similar to the now unsupported Grid Sight Index.
I don't seem to have it in my archives and after searching I can't find it.
It took recent price action and compared it to historic data and then plotted a most common next historic price movement on the chart based on the actions of the past.
Can anyone tell me what it was?
Cheers!!
