This oscillator has to be used in conjunction with other EW tools (certainly cannot be the main indicator).
EWO has: - Higher values during third waves' up - Lower but still Positive values during the first and fifth waves up - Negative values during the biggest corrections or downtrend impulse waves.
Personally, I am still trying to figure out EW, so do not use this. Just wanted to publish this for the EW masters out there who can put this to good use.
