What Role Does ‘Delta’ Play in Managing the Risk of a Short-Term Options Scalping Position?

Delta is the primary options Greek that measures the sensitivity of the option's price (premium) to a one-unit change in the underlying asset's price. For a scalper, Delta is crucial for quickly calculating the expected profit or loss for small movements.

By keeping track of the position's net Delta (Delta exposure), the trader can manage directional risk and determine the necessary hedging ratio to maintain a Delta-neutral position if desired.
