Delta (the Options Greek)

Delta runs from 0 to 1 for calls and 0 to −1 for puts, and roughly tracks an option's probability of finishing ITM. A deep-ITM option's delta approaches 1 (moves almost point-for-point with spot); a far-OTM option's delta approaches 0 (barely moves at all).

It's a coincidence of naming, not a connection: this page is about the Greek. DeltaK, both the terminal and the strategy it runs, is named for a different idea: the wall migration and rotation its engine reads, not the options Greek.

Example: a NIFTY 24,900 call, 100 points ITM, might carry a delta near 0.65, so a 10-point move in spot shifts its premium by roughly ₹6.50. A 25,200 call, far OTM, might carry a delta near 0.15, where the same 10-point move shifts it by about ₹1.50.
