In conclusion I would say that in periods when the MACD Histogram was negative and falling it would not have worked consistantly to buy the VIX when the RSI 5 was below 30. One such occasion occurred the last week of last month and would have worked nicely however.
I presume that in periods of high volatility an inverse of the VTO will not work. It does appear that buying the VIX when the RSI 5 was below 20 and selling above 80 would have worked on a negative weekly MACD signal. In some cases the hold was months long however I believe they all 4 worked.
I also note that there were 6 occasions when the VIX RSI 5 closed over 90 in the last 2.5 yrs. In every case it retraced below 50. Therfore it was an excellent place to take profits on shorts and possibly initiate new longs for a scalp.
