And now, a few hours later with price flat, we can see the decay effect (theta) on option values. The good thing about it is that even if the price has some move up or down, it still ends up in profit. It works most of the time, and an account gain of percent or two per trade adds up.
The downside to this strategy is that a large directional move is theoretically infinite, leading to unlimited loss. The other thing is that it requires a high amount of buying power relative to reward.
