Four simple tabs to study cash-secured puts and covered calls. Key in numbers, see an illustrated cycle return, then check buying power. This is for learning only. It is not a product offer, not a sure profit, and not advice to trade.

In simple terms

A cash-secured put means you set aside cash and may receive a premium. If the share stays above your strike until expiry, the option can expire and you keep the net premium (after fees). If the share falls to or below the strike, you may have to buy 100 shares per contract. That is assignment.

  1. Gross premium minus fees = net premium.
  2. Net premium divided by days = premium per day (illustrated).
  3. Net premium divided by (share price × 100 × contracts) = cycle return versus the share value.
  4. Cash needed is strike × 100 × contracts. If buying power is less, margin may be at risk.

Figures are in USD. Convert to ringgit at your own FX rate. A buffer below spot is not protection against loss.

Put working sheet

Illustrated put math

Sample: 300 − 4.38 = 295.62 net, 9.85 a day, 1.97% versus 100 shares at 150, 20% below spot, 1.5% of a 1,000,000 account if assigned.

In simple terms

A covered call means you already hold 100 shares per contract. You may receive a premium for agreeing to sell those shares at the strike. If the share stays below the strike, you keep the shares and the net premium. If it rises above the strike, the shares can be called away. Your extra upside can be capped.

  1. You should already own the shares. This calculator does not buy shares for you.
  2. Net premium = gross premium minus fees.
  3. Cycle return is net premium versus the value of 100 shares you already hold.
  4. Distance to being called = strike minus today’s share price.

This is not a sure income plan. Gaps, early assignment, and share losses can still happen.

Call working sheet

Illustrated call math

Uses the same account size and buying power you keyed on the put tab. Please confirm you already hold 100 shares per contract.

In simple terms

This tab only checks whether the buying power you typed can support the cash-secured put on Tab 1. If cash is short, it shows possible changes to study: fewer contracts, a farther strike, or a defined-risk spread. It also uses days left and current mid, if you fill them, to show hold / roll / close as study notes.

These notes are not advice to open, hold, roll, or close any contract. Please do your own research. Confirm buying power inside your moomoo app before you decide anything.

Study notes (not a recommendation)

    Possible changes to study

    Buttons only change the numbers on this page so you can compare. They do not place any order.

    Where the numbers come from

    Please treat orange labels as moomoo sources. Grey labels are third party. If OpenD is off, the study board uses a third-party snapshot so you can still learn the calculator. Refresh after OpenD is on if you want moomoo rows.

    How to read the labels

    moomoo = data that can come from your OpenD / moomoo account when connected. Third party = any other source, named clearly. Your typed numbers on Tabs 1–3 are your own inputs, not market data.
