How to Place Options Limit Orders

A practical guide for subscribers — brokerage walkthroughs, diversification, and the pre-trade checks that prevent the most expensive mistakes.

Why limit orders matter for options

A limit order says “I will sell this option for no less than $X” or “I will buy this option for no more than $X.” A market order says “just fill me at whatever the next available price is.” For single-stock options, that difference can be the difference between a profitable trade and an immediately losing one.

Options bid/ask spreads are wider than stock spreads. On a liquid stock the spread might be a single penny; on the same stock’s options it can easily be 5 to 30 cents wide, and on less-liquid names sometimes wider. A ten-cent spread on one contract is $10 of immediate cost if you cross it. On ten contracts, $100. The spread is the market maker’s compensation for providing liquidity, and you do not have to pay all of it.

When we publish a trade with a target premium of, say, $1.85 per contract, that number was derived from the chain we observed at the time of writing. By the time you place the order, the chain may have moved. A limit at our published target — or at the midpoint of the current bid/ask — gives you a chance to capture roughly the economics we modeled. A market order surrenders that control entirely.

The six fields on every options ticket

Every brokerage uses different language for the same six fields. Once you understand the six, the platform-specific labels stop mattering.

1. Action. Our published trades are almost always sell to open (you are the seller of the option, opening a new position) or buy to close (buying back a position you previously sold). The less-common pair is buy to open and sell to close. Picking the wrong action is the single most common entry mistake. Read this field twice.
2. Symbol and option type. The underlying ticker plus put or call. For a cash-secured put on Adobe, this is ADBE and put. For a covered call on Conagra, CAG and call. Most brokerages auto-derive the option type once you start building from a chain view.
3. Expiration date. Match the date we publish exactly. A trade at the January 15, 2027 expiration is materially different from one at the March 19, 2027 expiration even on the same strike and underlying.
4. Strike price. The price at which the option can be exercised. Match exactly. A $195 put is not the same trade as a $200 put.
5. Number of contracts. One contract represents 100 shares. A 1-contract $195 cash-secured put requires $19,500 of buying power on assignment. Always confirm. Entering 10 contracts when you meant 1 is a 10x position-size mistake.
6. Limit price. The minimum credit you will accept (when selling) or the maximum debit you will pay (when buying), per share. If we publish a $1.85 credit, your limit-price field is $1.85; the total credit on 1 contract is $1.85 × 100 = $185.

Two ancillary fields round out the ticket: time-in-force (DAY for routine entries, GTC for long-dated LEAPs you’re willing to leave open) and order type (always limit for our trades, never market).

Brokerage walkthroughs

Below are step-by-step instructions for entering a sell-to-open put — the most common Value Options Letter trade type — on the three brokerages our subscribers use most. Covered calls follow the same pattern with sell-to-open call substituted for sell-to-open put.

Charles Schwab (thinkorswim)

1. Search the underlying ticker. Click to load chart and chain.
2. Open the Trade tab → Options Chain.
3. Click the desired expiration to expand its strikes; match the date we published exactly.
4. Click the bid on the put strike you want. thinkorswim builds a sell-to-open ticket pre-filled at the bid. Verify: is the action SELL, the type PUT, the strike and expiration correct?
5. Adjust the limit price to our published target or the midpoint of the current bid/ask, whichever is more conservative.
6. Confirm Quantity. Set Time-in-force (DAY for most entries).
7. Click Confirm and Send. Read the confirmation pane fully — if anything reads wrong, cancel and rebuild.

Fidelity (web or Active Trader Pro)

1. Trade → Options Trade Ticket.
2. Enter the underlying ticker. Chain loads below.
3. Strategy: Sell to Open for new short positions.
4. Pick expiration and strike from the chain. Confirm Put.
5. Quantity, Order Type (Limit), Limit Price, Time-in-Force. Default is DAY.
6. Preview Order. Fidelity prints the credit, total proceeds, and estimated commissions/fees. Read these before submitting.

Interactive Brokers (Trader Workstation)

1. Type the ticker into the symbol bar. Press Enter.
2. Right-click the ticker → Trading Tools → Option Trader.
3. Pick expiration and strike. Click the bid on the put strike to start a sell-to-open ticket.
4. Verify Action: SELL with position effect “open.”
5. Set Order Type: LMT, set Limit Price, Quantity, TIF.
6. Transmit. TWS has no second “are you sure” by default — read the ticket before transmitting.

Picking your limit price

If we publish a trade at $1.85 credit and the current chain shows a $1.80 bid / $1.95 ask (midpoint $1.875), entering a limit at our published $1.85 is essentially asking for a fill at slightly below the midpoint. That is a reasonable, patient limit price — it will fill on most days when the market is functioning normally; it will not chase if the market backs off.

If you want immediate execution because the underlying is moving and you want to lock in elevated premium, moving your limit to the bid is fair. You leave a few cents on the table; you get filled. If you have strong conviction that fair value is closer to the published credit and you’re willing to wait, leave the limit at the target. You may not fill. That’s fine: a missed trade is far cheaper than a bad fill.

What is not defensible: cancelling and re-entering chase-style every five minutes with a slightly less attractive price each time. That’s a guaranteed way to overpay (or under-receive credit). Set the limit, let it work for the session, and either accept the fill or walk away.

Diversification — the only free lunch

Diversification is the single most important risk-management tool available to a retail options trader, and it is the one most commonly under-applied. A subscriber concentrating their entire options book in two or three large positions on correlated names is running a substantially riskier book than one with the same total capital deployed across ten or fifteen smaller positions on uncorrelated names.

We publish each trade independently. The portfolio question — how much capital, across how many positions, in which sectors, at which expirations — is yours. We strongly encourage ample diversification. None of the numbers below are personalized advice; the principles are well-established and we apply them to our own books.

• Position sizing. Many experienced practitioners cap the capital committed to any single underlying at a small single-digit percentage of total investable assets. The principle: no single trade, however compelling, should be capable of materially impairing the portfolio if it goes badly wrong.
• Sector spread. Many of our watchlist names are deep-value cyclicals — energy, financials, materials, consumer staples. These sectors correlate during macro stress. Spreading across sectors with different macro drivers is the standard mitigation.
• Expiration laddering. If every position you hold expires on the same Friday, that Friday will be unusually consequential. Spreading expirations across a few different cycles smooths the cash-flow profile of premium decay and assignment events.
• Cash reserves. A book at 100% buying-power utilization has no margin for adjustment, opportunistic entries, or surprise. Keep cash buffer outside committed positions.
• Recovery time. Behind every diversification rule is the same idea: if any single thing goes wrong, the portfolio should be able to recover from its remaining holdings and ongoing income within a reasonable horizon. Concentration shortens that horizon — sometimes catastrophically.

Skipping a trade we publish is a perfectly legitimate decision, made every day by experienced investors managing their own diversification. There will be another idea.

Common mistakes

• Wrong action. Selecting Buy to Open instead of Sell to Open converts a credit trade into a debit trade. Catch it on the confirmation pane; if it fills, close and rebuild immediately.
• Wrong contract count. The buying-power impact line is your friend.
• Wrong expiration. Stacked expirations are easy to misclick. Match the published date exactly.
• Wrong strike. Strikes display in tight increments. The confirmation should echo the strike — read it.
• Wrong ticker. BRK.A vs BRK.B; CVS vs CVX. The company name printed at the top of the chain should match what we wrote about.
• Chasing premium on names you would not own. Every cash-secured put we publish is on a name we would happily own at the effective entry price. If you’re attracted to a high-premium put on a name we haven’t vetted, ask whether you would buy the underlying outright at strike-minus-premium. If no, the trade is not for you.
• Forgetting GTC orders survive overnight news. A GTC limit placed Friday afternoon will fill at Monday’s open at your stale limit price if news breaks Sunday. For event-sensitive entries, DAY orders are safer.

Pre-trade checklist

Before clicking Submit on any options order, walk through this list. It takes 30 seconds and prevents the entire mistake list above:

• Ticker — company name on the chain matches what we wrote about?
• Action — Sell to Open for new shorts; Buy to Close to exit.
• Type — Put or Call; matches the trade.
• Expiration date — exactly the date we published.
• Strike — exactly the strike we published.
• Quantity — the contract count is what you intend.
• Limit price — at our target, or at the current midpoint if the chain has moved.
• Buying-power impact — the dollar number is approximately what you expect.

If anything reads wrong, click Cancel, take a breath, and rebuild from scratch. The cost of rebuilding is 60 seconds. The cost of submitting a wrong order is sometimes thousands of dollars.

What to do next

• Print the pre-trade checklist and tape it next to your trading screen. Old-school but effective.
• Set up a paper-trade or single-contract entry on a well-vetted name to walk the workflow once before going full-size.
• Read Cash-Secured Puts 101 and Position Sizing for Options Income if you haven’t yet.
• When the next Value Options Letter trade lands, walk it through the six-fields framework and the eight-point checklist before clicking Submit.
