How many option contracts should you sell?

Sell one contract until you've closed at least ten trades. After that, let a cap per stock, as a share of your account, decide the number. The premium should never decide it.

The short answer

One. Sell one contract at a time until you've opened and closed at least ten trades. That's enough to see a put expire, get assigned, sell a call, and maybe get called away, with mistakes that stay small.

After that, the number comes from a simple rule: decide the most one stock can take, as a share of your account, then fit as many contracts as that allows. Round down. If even one doesn't fit, the stock is too pricey for your account.

Why one contract first

The wheel strategy looks simple on paper. In practice, the first ten trades teach things a page can't:

• What an assignment looks like in your account, and how it feels.
• How wide the spreads really are on the stocks you like.
• How often you'll want to break your own rules.
• How much time each position takes.

Every one of those lessons costs money. With one contract, it costs a third as much as with three. Ten trades with one contract is cheap tuition.

Ten isn't magic. It's a round number that usually covers a few cycles, including at least one that goes wrong. If your first ten trades all win, keep going at one contract until one doesn't. You'll learn more from that one.

One contract vs three (an illustration, not a trade idea)

You have $15,000. A made-up stock, XYZ, trades at $27. Its 30-day $25 put pays $0.60.

• One contract: $60 collected, $2,500 promised.
• Three contracts: $180 collected, $7,500 promised.

Three contracts triple every row: the wins and the losses. The odds don't change. The size does. With three contracts, half your account rides on one stock. With one, it's about a sixth.

The account-percent rule

Once you've closed ten trades, use this to decide the number.

1. Pick a cap per stock. The most of your account any one name can take. Write it down.
2. Turn it into dollars. Account × cap.
3. Divide by one contract's obligation (strike × 100). Round down.

Here's that rule for a $15,000 account with a 20% cap ($3,000 per stock):

The zero row is the rule working. It stops you from forcing a stock that doesn't fit.

Shares you already hold count too. If you were assigned on XYZ and hold 100 shares at $25, that's $2,500 of your $3,000 XYZ cap already used. You can't sell another XYZ put until those shares are gone. See position sizing for selling options.

Stepping up, slowly

When you're ready to sell more, a few habits keep it calm:

• Spread across names before stacking one. Two contracts on two different stocks beats two on the same stock. See diversifying a wheel portfolio.
• Add one contract at a time. Going from one to two is a big step. From one to five is a leap.
• Never add after a loss to "win it back." That's when size grows fastest and judgment is weakest.
• Stagger the dates. If you hold more contracts, put them on different expiry dates so one bad Friday doesn't hit all of them.
• Check your total promised. Add up every put's strike × 100. It should never be more than the cash you have, if you're running cash-secured. See keeping cash aside for assignment.

Small accounts may not get past one contract for a while. That's fine. See can you wheel with a small account.

A note on accounts. In the US, IRAs and cash accounts usually hold the full strike for each put, so the number you can sell is capped by your cash. In Canada, covered calls are widely allowed in a TFSA or RRSP, while cash-secured puts depend on the broker. Options permissions differ by broker.

What to do with your next trade

1. Count your closed trades. Under ten? Sell one contract.
2. Over ten? Write your cap per stock. Divide it by the strike × 100. Round down.
3. Before you place it, write the "stock falls 20% below the strike" loss for that number of contracts.
4. If that loss would make you change your plan, sell fewer.
