Accumulate-only — never sells. Each period a fresh ₹/period of earnings joins a waiting pool. You arm one buy rung per waiting tranche at −step, −2·step, −3·step%… below prev close. Rungs that fill are consumed; unfilled tranches carry forward and re-ladder next period (so 1-of-3 filled → 2 carry + 1 new = 3 again). The position only grows — final value is the whole holding marked to the last NAV. Watch deployed %: a shallow dip-step against frequent cadence leaves cash idling in the waiting pool.
