This is why the delta is important; it takes much of the guess work out of the expected price movement of the option.

What is delta in options?
Delta serves as a proxy for probability of success at expiration of the option contract. This value is an absolute number thus a negative (put side of the option chain) or positive (call side of the option chain) value is irrelevant. The interpretation of Delta is based on 1.0 less the delta at a given strike. If the Delta is -0.14 on the put side then this translates into 1.0 - (-0.14) = 0.86 thus a ~86% probability of the trade expiring above the strike or being worthless at expiration. If the Delta is 0.20 on the call side then this translates into 1.0 - 0.20 = 0.80 thus ~80% probability of the expiring below the strike or being worthless at expiration. Selling options near a specific Delta that is out-of-the money places the statistical edge in your favor. Given enough trade occurrences, the probabilities will play out to reach their expected outcome. Thus trading at a Delta of 0.15 will yield a winning trade success rate of ~85% if all trades go to expiration.
