Table column guide

Every table field, its calculation, and how to read it. Hover a column heading for the same quick explanation.

Ticker

The exchange ticker plus the Moomoo company or fund name. The badge identifies a stock or ETF.

Market

Listing market used for the quote and option chain: US or HK.

Currency

Native trading currency for the underlying and option contract: USD or HKD.

Lot size

Shares controlled by one option contract. US equity options are usually 100 shares; Hong Kong contracts can vary.

Put contract

Moomoo’s unique code for the cash-secured put contract, including market, ticker, expiry, put marker, and strike encoding.

Premium / share

Current best displayed bid per share in the contract’s native currency. This is the conservative premium used by the screener.

Premium / contract (SGD)

Bid × lot size × configured SGD exchange rate. This estimates the gross premium for one contract before fees and taxes.

Premium yield

Gross premium ÷ cash collateral × 100. It measures the return for the option term, before fees and taxes.

ROC % / day

Premium yield ÷ days to expiry. It compares capital efficiency across options with different expiries; it is not a guaranteed daily return.

Collateral (SGD)

Strike × lot size × configured SGD exchange rate. This is the cash-secured amount needed for one contract, before any broker-specific margin treatment.

Annualized yield

Premium yield annualized from the contract’s days to expiry. It is a comparison metric, not a forecast of repeating returns.

Score

Composite 0–100 ranking from the configured return, liquidity, spread, IV, support, event, collateral, and delta rules. Open the score ledger for adjustments.

Risk

Risk classification. The icon abbreviates the full status available in the row’s expanded evidence.

Action

Suggested research action. Sell candidates have no soft warnings; wait or skip candidates require further review. This is not trading advice.

Earnings

Known next earnings date for a stock, or N/A for an ETF. Earnings before expiry or an unknown date reduces the score.

Expiry

The option’s expiration date. Assignment, if any, is determined at expiry under the broker’s and exchange’s rules.

Days

Days to expiry, calculated from the report date to the option expiry date.

Strike

Put strike price in the native currency. If assigned, the wheel strategy would generally buy the lot size of shares at this price.

Delta

Option delta from Moomoo. For a put it is negative; its absolute value is a rough sensitivity and probability proxy, not a probability guarantee.

Underlying

Latest underlying share or ETF price used by the screen, in native currency.

Fair value (Owner earnings DCF)

Owner-earnings DCF estimate per share for eligible non-financial stocks. It is a model estimate, not a market target or valuation guarantee.

Cost basis

Strike − premium per share. This estimates the share cost basis if assigned, excluding commissions, taxes, and any subsequent adjustments.

Cushion

Percentage distance from underlying price to the effective cost basis. A higher value provides more room for a price decline before the estimated basis is reached.

Option IV

Implied volatility for the option, annualized by market convention. It reflects option pricing expectations, not a prediction of realized volatility.

Annex — option-chain filter audit (0 without an initial contract match)

The first Moomoo request applies configured DTE, delta, and open-interest filters. NO MATCH means no contract remained after those filters; it is not a failed underlying screen.

How option scores work

Hard rejection → score 0Invalid bid/ask; DTE outside 30–50; missing delta; or |delta| > 0.30. Result: Review required / Skip.

Starting scoreEligible contract starts at 45.

Quality adjustmentsOI ≥500: +5, otherwise −10; IV inside range: +5, otherwise −10; strike within support ceiling: +5, otherwise −10; spread ≤10%: +5, otherwise −10; collateral within cap: +5, otherwise −15.

Event adjustmentKnown earnings after expiry / ETF: +5; unknown earnings: −5; earnings before expiry: −15.

Return on capitalDaily ROC = option premium ÷ secured collateral ÷ DTE. Rating: 5 ≥0.10%/day; 4 ≥0.075%; 3 ≥0.05%; 2 ≥0.025%; 1 <0.025%. Rating is shown in the option hover card and CSV.

Reward adjustmentsCushion ≥9%: +10 to +15; capital efficiency: +10 when premium yield ≥1% or annualized yield ≥20%; preferred delta: +10; spread ≤5%: +5; OI ≥1000: +5.

Final decisionScore ≥75 AND no warnings: Good / Sell small. Any soft warning: Caution / Wait. Scores are clamped to 0–100; the hover score ledger shows every applied adjustment.
