So to calculate the , you can 'reverse engineer' the 'reverse engineered rsi'.
This can be done by taking the distance between the current price and the "50-level ema"
you can then normalise this by dividing with the atr or the st dev to end up with a chart that's almost exactly like the line
As OB/OS levele, a multiplier of the atr or st dev can be used
one application for this is to quickly refer to MTF levels by multiplying th 27 value with the timeframe multiplier
as it turns out, I discovered that the ema's with multiples of 27 as a period align with the 50-level line of the of all the corresponding timeframes.
