When the market-vol index (VIX) is at/above this level the tape counts as elevated and the IV rank floor is relaxed — per-name IV ranks lag a broad-vol regime while absolute premium is rich.

IV-rank points subtracted from the floor while elevated (e.g. floor 45 → 35). 0 disables the market-vol regime check.

Once elevated, the relaxed floor persists until VIX falls to/below this level. Blank uses the derived default (threshold − 3, e.g. 25 → 22) — keeps the relaxed floor through the post-spike decay (elevated-but-falling vol, the best short-premium entry window) instead of flapping the floor every cycle at the line. Note: editing the threshold or release starts the regime fresh under the new band (a latched regime does not carry over) — this is also the manual-release lever.

While the market-vol IVR relaxation is active (VIX elevated + contango), the screener uses this band instead of the normal one: rich premium buys the same credit at lower delta. Both fields must be set for the shift; clearing either reverts to the normal band.

Upper edge of the elevated-regime band (must stay above its min). Default pair 0.10–0.22, below the preset normal band 0.16–0.30.

Companion to the $ cap, applied per structure: package spread ≤ this % of the sum of leg mids at packaging/approval, and a naked single leg's spread ≤ this % of its mid. Catches cheap structures where the $ cap is proportionally huge. Blank or 0 = disabled.

Third spread companion (V420), applied per assembled package: aggregate spread ≤ this % of the package's net credit. Leg mids sum while credits cancel, so a package inside both caps above can still pay a large share of its credit crossing the spread. Blank or 0 = disabled (ships off).

Short-leg strikes with a known open interest below this are dropped (day volume is spoofable by one print; resting OI is not). Unknown OI passes (fail-open). Blank = disabled.

Strikes/packages with estimated POP below this percentage are dropped before discovery / AI. Applies to single-leg shorts and put/call credit verticals.

Separate, normally lower floor for iron condors: an IC profits only when price finishes between two short strikes, so its probability of profit is structurally below a one-sided vertical's. Using the verticals floor here would reject every condor. Leave blank to use the engine default.

Separate floor for short strangles (V430): a strangle's POP is 1 − (Δcall + Δput), structurally below a one-sided vertical's, so the verticals floor bars the shape entirely at the deployed delta band. Blank (the shipped state) = strangles keep gating on the verticals floor above.

Relieved floor (V431) for a strangle or iron condor whose band-containment check measured the short-strike band and passed: the containment evidence substitutes for part of the delta-derived POP model, and the package gates on min(structure floor, this). Missing candle history never qualifies. Blank (the shipped state) = no relief.

Tag-and-ratify relief (V432): a known IV rank in [this, the pass’s effective IVR floor) (the configured floor after any elevated-VIX relaxation) admits the symbol tagged as relieved, and packaging then drops every package that is not a band-verified two-sided structure — the relieved door cannot leak into the vertical or unverified book. Blank (the shipped state) = no relief.

Relieved variance-risk-premium floor (V432, decimal vol points) for band-verified packages: the entry gate applies min(IV−HV floor, this). Rationale: trailing HV carries the post-earnings gap while IV has crushed, so the deployed floor mis-reads exactly the post-print window the earnings gate admits. Never imposes a floor when the deployed key is blank. Blank (the shipped state) = no relief.

Absolute width cap (V433) on the band-verified tag: a two-sided package whose short-strike band (upper − lower) / spot exceeds this still passes the containment screen but earns none of the band-verified reliefs. Runs 276–279: delta-targeted strikes make containment IV-conditional, so without an absolute bound the reliefs flow to exactly the high-IV names whose forward vol is the risk. Blank (the shipped state) = no cap.

V436: how many trailing sessions the containment screen measures over. This is the structural parameter behind the containment floor — the band program’s only promotion — and until this key it could not be A/B’d at all, because every arm of a replay round shares one build and a config property cannot vary between arms. The floor of 20 exists so the DTE-matched hypothesis is expressible: the screen looks back 60 sessions while the trade’s risk horizon is 45–60 calendar days ≈ 31–41 sessions. The ceiling of 120 is what live can supply. Blank (the shipped state) = the engine default of 60.

V433 (mode 3 added by V437): 1 places strangle/condor short strikes at the first chain strikes outside the trailing closes’ min/max ± buffer; 2 projects an OLS regression channel to the candidate’s expiry so strikes lean with drift; 3 is the drift cone — the union of that channel at the last observed session and at expiry. Mode 2 straddle-tests the projected channel, so on a trending name it lands off spot and silently falls back to delta pairing on exactly the drift cases it exists to handle (run 284: 9 of 11 shared rows unchanged); the cone straddles spot whenever the price sits inside its own current channel. Placement only — admission stays with the containment screen. Verticals keep the screened delta strike; falls back to delta pairing when the band cannot resolve. Blank/0 (the shipped state) = delta-targeted strikes.

V433 placement buffer beyond the band edge (0.02 = short put 2% of spot below the band low). Read only while the placement mode is armed. Blank (the shipped state) = no buffer.

Close any position showing a profit once DTE ≤ Target DTE instead of riding the high-gamma final weeks.

Force-close at/below this DTE regardless of P&L. 0 = off.

Peak captured credit at which the trailing profit-lock arms.

Close once an armed position gives back this share of its peak profit — a winner never round-trips to a loser.

Least credit that must already be captured before the in-profit time stop banks at Target DTE. 0 = bank any profit. A value at or above the profit target is clamped to it. Defined-risk structures only. If you set this above 0, keep the min DTE floor above 0 too — otherwise a below-floor winner has no time-based exit left.

0 = off (shipped). 1 = close once the underlying reaches or passes the short CALL strike. 2 = that, and only when the daily-candle trend read is a confirmed uptrend on the same session. Call side only.

How much of the collected credit must ALREADY be given back before the geometry exit fires. Blank = no such condition, so it fires on the strike breach alone whether the position is up or down. This is a floor on the LOSS, not on profit — 0 is not “off”, it means “only when the position is not in profit”.
