VOLATILITY Here is my bookmark for the VIX

This is a chart on the S & P 500 index, but overall for market conditions you can use if for any index. I believe TOS have a volatility reading on one of those columns? I've been playing with gamma and delta this past week, trying to find some correlation to price action in TOS.
I use VIX two or three times a week and it is a general market directional indicator. 25 is the neutral number. Above that the market is bearish and below that the market is bullish.
That said, there is a grey area between 20 and 30 when things go to extremes. Rotating around the 25 line, which is right now. The market is just churning directionless.
The VIX gives you an idea how to play your trades. You can run a trend line along the peaks or valleys and generally predict the next day's action from this.
A bullish VIX below 20 means daily bars are tightening up shorter in length and above 30, things are going hairy with big drops and long bearish bars. You can make good money in the bearish market, playing the down trends. Upside bullish trends you can do spreads, or Iron Condors quite comfortably and just put an Iron Condor any time the rising trend line momentarily corrects for 3 or 4 days. Wait till it starts to rise again and put an Iron Condor. Or Bull Put spread.
When trading journal talks volatility it can get confusing. I call what you were doing earlier this week PREMIUM BALLOONING, WHEN you are trying to place a spread while a trend is going. If you catch the trend BEFORE the turning point, you get maximum premium ballooning in price to SELL your SPREAD into that you expect to go down. You collect the most money when you SELL. Once the trend stalls, or turns to go sideways, your premium will deflate like sticking a balloon with a pin. You can actually trade off the change in volatility, or premium ballooning and collapsing. The short straddle worked like this. Just that $9000 a contract margin was way too high for me. You had the right idea this week, when you ran that question before. You SELL the spread into the premium ballooning.
