Zenith

Zenith is Aegis's mirror on the call side: the strike above spot carrying the heaviest open interest or the heaviest session volume, again whichever of the two sits nearer spot, read live rather than fixed at the start of the session. A solid Zenith is what allows a put entry under Protocol Alpha or Gamma; a migrating Zenith is read as resistance being ceded, not just tested.

Example: call OI stacked at 25,200 for a full week while NIFTY tests that level twice and fails both times reads as Zenith holding firm as resistance. A close above 25,200 with OI actively unwinding there instead reads as Zenith being ceded, a materially different signal from simply testing the level and bouncing off it.
