Excellent post. I would take this even one step further. The best trades are green very quickly. We are best served to exit all losing trades quickly and wait for a better entry. It's important to enter with the mindset that we may have to make 2 or 3 entries to get a good one. So we have to...

A several point up move in IV seems likely over the next 3 months.

Looking at the greeks for the 225 calls, the delta is .015 and vega is .12. So a $1 up move in price only $0.015 increase in the price of the option. A 1 point up move in IV increases the option price $.12 or about 2X what was paid for it.

Not surprisingly, SPY seems to be the best bet for this strategy of buying far OTM calls about 3 months out. It's easy to forget that for these to payoff, we either need a decent rally OR almost any kind of selloff. I looked at VXX, IWM, AAPL and SPY seems to offer the best reward to risk...

This seems correct to me, especially given the size of the trades. Some of them though are actually huge bets on direction by very confident speculators.

Also, a time stamp within seconds and the same number of contracts indicates 2 or more trades that are connected (legs).

"IV for these 225 calls is about .11 vs about .16 for the ATM 200 calls" Contrast these with the puts, where you have to go all the way to the 113-116 strikes to find similarly priced puts. The IV for these put strikes is about .44 or about 4X that of the calls. The delta is well below 1 for...
