Since this is a basic introduction to options trading, we will be focusing on executing simple orders that just involve buying options.
From the options chain screen, you will have selected the option you wish to purchase by clicking on the options symbol. A separate order entry screen will be displayed and here, you have several things to specify to complete your order.
Quantity
After confirming the underlying, exact expiration date, call/put type, strike and buy-to-open instruction, specify the number of contracts. A standard U.S. equity option usually represents 100 shares; adjusted contracts can differ. Multiply the quoted premium by the premium multiplier and quantity, then include all applicable charges. Fees and volume discounts depend on the broker.
All or None
Where supported, an all-or-none instruction requires the entire specified quantity to execute or none of it. It can reduce the chance of a fill. Availability and handling vary by product, venue and broker; do not assume every option limit order supports it. An all-or-none order is not the same as a fill-or-kill order, which also imposes immediate execution.
Price, duration and confirmation
A limit order sets the maximum buying price or minimum selling price; it does not guarantee execution. Confirm time in force and whether a displayed spread price is a net debit or credit. Check the broker’s acknowledgment, fills and remaining quantity. Submitting or cancelling an order is not proof that it filled or that cancellation succeeded.
Verify a complete order preview
Suppose you want two $100/$105 bull call spreads for no more than $2.10 each. The preview should show buy to open two $100 calls and sell to open two $105 calls, with matching expiry and deliverable. A $2.10 net debit means $420 total before fees, not $210 for both spreads.
To close that position, sell to close the two $100 calls and buy to close the two $105 calls. Reversing only the strike selection or using sell to open on a contract you do not hold can create a different position. Verify quantity after any partial fill before sending another ticket.
A preview checklist
- Underlying, option type, expiration and strike match the plan.
- Every leg’s direction and open/close designation are correct.
- Package quantity is distinguished from total leg contracts.
- The debit/credit label and estimated cash flow agree.
- Duration, limit, fees and estimated capital effect are understood.
The broker’s buying-power estimate is not a maximum-loss guarantee. Check the resulting positions and working orders after execution. If one spread out of two fills at $2.05, $205 has been committed before charges and one spread remains pending; an unchanged ticket quantity is not evidence that nothing traded.
