TT, I used 777 (7 bar, 7 average, 7 period) for the standard Fisher. I did some backtesting last night, I added a 20 bar, 34 bar, 44 bar Fisher RSI to the chart. It appears to me when the 7 bar passed the 20/34/44 bar Fishers, it was a buy/cover. Otherwise, stay in the short position (as of this morning).
