ML Options Explorer

Researches options strategies across many stocks and ranks candidates by expected value, risk, liquidity, and validation confidence.

This explorer does not optimize for 100% win rate. High win rate can hide rare large losses. The goal is durable expected value after realistic costs, liquidity, risk, and validation.
Outputs are research candidates — not personalized investment advice.

Methodology — pricing, scoring, strategy mechanics

Pricing modes

Model — Black-Scholes premium estimated from 60-day historical volatility. Risk-free rate is implicit at zero. Greeks (delta) are computed from the same model.
Live chain — bid / ask / mid / IV / Greeks pulled from the option chain endpoint when available. Mid is used for yield math; risk-flag wide_spreadfires when bid/ask > 5%.
Hybrid — live chain when present; falls back to model. The status bar surfaces the actual source per request.

Strategy mechanics

Covered call — own 100 shares, sell a short call. Premium = income cap, strike = sell price ceiling. Breakeven = purchase price − premium received.
Cash-secured put — set aside strike × 100 cash, sell a short put. Breakeven = strike − premium. Capital required = strike × 100 per contract.
Wheel — sell CSPs until assigned, hold the stock, sell CCs until called away, then restart. Adjusted basis tracks premium received less stock losses.

Scoring (composite 0..100)

Each strategy decomposes into 6–8 weighted axes — premium quality, assignment fit, downside risk, liquidity, IV attractiveness, event risk, historical outcome, goal fit. The composite is multiplied by a risk-penalty product (each ≤ 1.0) so wide-spread, low-sample, model-only, or earnings- inside-DTE setups grade down even with a strong raw composite.

Confidence grading

n < 5 — Very low (do not rank as strong)
5..10 — Low
10..20 — Moderate
20..50 — Good
≥ 50 — High

Model-only premium and missing liquidity data each downgrade by one tier.

Decision labels

Conservative income — low delta, broad breakeven, low assignment risk.
Balanced income — 0.20–0.35 delta band, moderate premium + assignment.
Aggressive income — higher delta, higher premium, frequent assignment.
Exit strategy — high-delta call on shares you want to exit.
Assignment candidate — CSP at a strike you want to own.
Avoid chasing premium — composite low or risk penalties dominate.

Limitations & disclaimer

Liquidity, spread, IV rank, open interest, earnings date, and ex-dividend date are surfaced only when the upstream provider supplies them. Missing fields render explicit fallback labels ( Unrated, N/A) — never fake values. Backtests assume entries from a deterministic rule and exit at expiration; real-world slippage, commissions, and early-assignment outcomes are not modelled. This page surfaces analytical projections derived from public market data — not personalised investment advice. Options involve risk, including loss of principal and the risk of assignment. Do your own due diligence and manage risk according to your situation.

Metric glossary

Success rate

Share of historical trades that finished above the short strike at expiration (CC) / above the put strike (CSP).

Strict success

Share of trades that hit success without ever touching the assignment zone intraday.

Premium yield

Premium received / capital required, per trade. CC denominator = stock cost; CSP denominator = strike × 100.

Annualized return

Premium yield × (365 / DTE). Short-DTE annualisation can inflate the number — interpret with the inflated_annualized risk flag.

Median return

Median total return (premium + stock P&L) across the historical sample.

P10 / P90

10th / 90th percentile total return — the tails of the historical distribution.

Assigned

Share of historical trades where the short option finished ITM and shares were transferred at the strike.

OTM

Out-of-the-money at expiration — the short option expired worthless.

Deep ITM

Short option finished significantly past the strike (e.g. > 2% past) — missed upside on CC, larger loss on CSP.

Breakeven

CC: stock cost − premium received. CSP: strike − premium received.

Max profit

CC if assigned: strike − stock cost + premium. CSP if expires OTM: premium received.

Downside exposure

Stock value declines reduce CC returns; CSP loses if stock falls below breakeven.

Assignment probability

Probability the short option finishes ITM at expiration (delta is a rough proxy).

Early assignment risk

ITM short calls are at risk of assignment before expiration when ex-dividend falls inside the trade and remaining extrinsic value is below the dividend.

Opportunity cost

Returns forgone vs simply holding the stock — capped upside on CC, time-locked cash on CSP.

Missed upside

Gain above the strike that CC trader did not capture due to the cap.

Downside capture

Share of stock-only downside the strategy retained, even after premium offset.

Stock-only return

Hypothetical return of just holding the stock over the same window — baseline comparison.

CC excess return vs stock

Covered-call return minus stock-only return. Positive when premium > foregone upside.

CSP excess return vs cash

Premium yield on collateral minus cash / T-bill return over the same window.

Wheel cycle P&L

Total premium + stock P&L from one CSP → assignment → CC → called-away rotation.

Days in stock

Calendar days the wheel held assigned shares during the cycle.

Capital efficiency

Annualised return on capital, accounting for days-in-cash vs days-in-stock.

IV rank

Where current implied volatility sits in its 52-week range (0..100).

IV percentile

Share of days in the past 252 trading days where IV was below today's level.

Bid/ask spread

(ask − bid) / mid. Wide spreads make modelled mid yields harder to execute.

Open interest

Outstanding contracts on the strike. Below 100 makes the option illiquid.

Option volume

Today's traded contracts on the strike. Below 50/day is illiquid.

Liquidity grade

A / B / C / D / Unrated derived from bid/ask spread, OI, and volume.

Low-N sample warning

Backtest with n < 20 → low confidence; n < 5 → very low (do not treat as repeatable).
