em13 is the third hex character from the x.
Each character in xFF5 corresponds to the strategy on the appropriate line above. “O” stands for Open and “F” stands for Flap. Both need some more work, but they work better than legacy indicators.
The top table shows how the market environment has changed since the beginning of September. The green area is all C and F readings while the bottom is mixed but obviously weaker.
SPY was weak enough late yesterday to produce an x33, for em13 but it wasn’t at all tempting to buy with such a lack of consensus.
