How to Sell Cash-Secured Puts on Fidelity: Step by Step

This is an educational walkthrough of the mechanics on Fidelity — not a recommendation to place any specific trade, and screen layouts change over time, so always confirm against Fidelity's current interface. Two prerequisites come first.

Options approval. Selling cash-secured puts requires an options-approved brokerage account. In Fidelity's tiers, selling cash-secured puts sits at a level that permits writing puts secured by cash. You apply under the account's options application; approval can take time, so do it before you plan to trade, not the day of.

Cash. A cash-secured put requires settled cash equal to the strike price times 100. A $50 strike put needs $5,000 available. Fidelity reserves this cash as collateral while the put is open, so it cannot back other trades. Confirm the cash is settled — recently deposited funds may not be immediately usable to secure a put.

Choose a stock you would genuinely be happy to own at the strike — the first rule of cash-secured puts. Then decide your strike and expiration based on how much premium you want versus your assignment tolerance. A strike further below the current price is less likely to be assigned but pays less; 30–45 days to expiration is a common educational window.

Before committing, run the numbers in the cash-secured put calculator: it shows the cash required, premium income, annualized yield, and your breakeven if assigned. Confirm no earnings report falls inside your expiration — an earnings gap is the most common way a cash-secured put goes wrong.

On Fidelity (web or Active Trader Pro), search the ticker and open the Option Chain. Select the expiration date you chose, then look at the puts side of the chain. Each strike shows the bid and ask; the premium you'd collect by selling is closer to the bid. Note the bid-ask spread — a tight spread (a few cents) indicates liquid options, which matters for getting a fair fill and exiting later.

Identify the specific put — your chosen strike and expiration — and confirm its premium is high enough to be worth the capital committed, using the annualized yield from the calculator as your yardstick.

Select the put and choose Sell to Open. Key order fields:

• Action: Sell to Open.
• Quantity: the number of contracts (1 contract = 100 shares = one full cash requirement).
• Order type: a limit order is strongly preferred over market — set your limit at or near the bid (or the midpoint) so you control the premium you receive.
• Time in force: Day or GTC.

Fidelity should recognize the order as cash-secured provided you hold the required cash, rather than treating it as a naked put. Review the estimated cash requirement and premium on the confirmation screen, then submit. Once filled, the premium is credited to your account and the collateral is reserved.

After the order fills, monitor the position. Two outcomes:

• The stock stays above the strike: the put loses value as time passes. You can hold to expiration (it expires worthless and you keep the full premium) or buy to close early once you've captured 50–70% of the premium, freeing your capital to sell another put.
• The stock falls below the strike: you are likely assigned 100 shares per contract at the strike, and your reserved cash buys them. You now own the stock at an effective cost basis of strike minus premium. From here you can hold the shares or sell covered calls against them — the start of the wheel strategy.

Plan both outcomes before you enter. The template above transfers directly to other brokers — Schwab, Robinhood, E*TRADE — since only the interface differs; the sell-to-open, cash-secured mechanics are the same everywhere.
