This is xFC for 13 em. That is the third hex character in the xEM column. The F for 8/12 is combined with the C on 8/11 to make xFC.
That is a flat signal when trend following is not in force. It is the least reliable of the four bull signals: xCC, xCF, xFF, and xFC. Performance in xFC is mixed but leans negative.
Those numbers might look better than they should because trend following was active for one of the 16 days that produced a nice gain. Trend following is not active currently.
