How do I use Delta to select a strike that strikes a balance between leverage and probability of success?

The short answer
Using delta to select a strike means weighing higher-delta options, which cost more but track the stock more closely and carry a higher probability-proxy of expiring in the money, against lower-delta options with more leverage.
How it works
A moderate delta range, often cited around 0.30 to 0.70 depending on strategy, is commonly used to balance the cost and leverage of lower-delta contracts against the higher cost and lower leverage of higher-delta contracts.
An example
Choosing a 0.50 delta call rather than a 0.20 delta call reduces leverage per dollar spent but increases the rough statistical likelihood, per the delta proxy, of finishing in the money at expiration.
Risk & limitations
Delta as a probability proxy is only an approximation from pricing models, not a guaranteed outcome, and actual results depend on the stock's real price path and volatility changes.
