fwiw, if one likes to trade the spy or es, my favorite strategy has been to take the current vix and multiply it by ~3. in the past few months that would approximately correlate to 6.5 - 7.5 spy points. now if the spy drops or rises by the stated amount within 3-5 days and gets close to or hits a major support or resistance level, this would present a very high probability trade to go long if spy drops or go short if it rises. this strategy is perhaps best suited for those who are position or swing traders. of course, because many of us are prisoners of our hard wiring, I have not always been profitable. also, since nothing is a sure thing appropriate targets and exit points need to be followed. I have observed that if there is very little reaction to the move ~16-36 hours on 4 hour chart it may be best to just exit the trade or follow the trend. there may be flaws in what i have mentioned so caveat emptor. if anyone has suggestions or knows how to test with historical vix data, please post. this strategy begs the question, " where was I when the market moved so aggresively within the 3-5 days." answer: 60 work week.
