Quantum Horizon
DeltaK's live ITM/OTM boundary through the option chain — the at-the-money line, redrawn tick by tick as spot moves.
Everything to the left of the Quantum Horizon is in-the-money for calls; everything to the right is in-the-money for puts. It's the same ATM concept every options trader already uses, just rendered as a literal, moving line through the live chain rather than something you have to mentally locate yourself strike by strike — and the reference point every payoff diagram on this wiki is drawn against.
Example: with spot at 24,975, the Quantum Horizon sits between the 24,950 and 25,000 strikes — everything at or below 24,950 is ITM for calls, everything at or above 25,000 is ITM for puts. The instant spot ticks past 25,000, the line itself redraws to sit past it, no manual recalculation required.
