Short-put roll finder: buy back the deep-ITM put, sell a new one

2026-08-17 14:43 SGT · IBKR live, ET 2026-08-17 · read-only, no orders. Old put bought back at ASK, new put sold at BID, same contract count unless stated. Beta-delta uses Risk Navigator betas; margin proxy is a TIMS-style scan of the put alone at the name's IBKR margin interval (directional; the real number is the account whatIf).
How to read it. Plan 1B buys each deep put back outright: 100% of the put's delta gone, cash out = the intrinsic. A roll instead sells a new put at a lower strike, so you get some credit back but keep some delta and some assignment exposure. For each old put the table lists four named rolls per expiry (cash-neutral: lowest strike that still pays for the buyback; ATM; ~15% OTM; ~30% OTM) with: how much of the buyback's delta reduction it achieves, the net cash, the time value you would be selling, and whether the new put is already in early-exercise territory. Full strike ladders are under each "all strikes" toggle.

Caveats. Off-RTH quotes are FROZEN/DELAYED; re-run in RTH before acting. Bid for the new put is conservative (you may fill nearer mid). Time value sold is upfront credit that decays in your favour only if the stock stays above the new strike; it is not covered-call income. Beta-delta removed is what the roll does to leverage today; a lower-strike put re-accumulates delta as the stock falls. The margin proxy ignores the long call and hedge put in the same sleeve; the fortress as a whole will need less than the put alone. This tool places no orders.
