Is a wider credit spread riskier?

A wider spread collects a bigger credit and has a bigger maximum loss in dollars. For the same short strike, the loss per spread grows with the width, so a wider spread needs fewer contracts to reach the same total risk. Size by the maximum loss, whatever the width.

When should you close a credit spread early?

Many traders set a profit target, such as buying the spread back once it has lost half its value, and a loss rule tied to the short strike or a multiple of the credit. Closing early gives up the last part of the credit in exchange for removing the risk of a late move or an early assignment.

How to Choose Strikes for a Credit Spread

Q: How to Choose Strikes for a Credit Spread

Pick the direction first, then put the short strike beyond a price level you expect to hold. Choose the width from the dollar loss you can accept, check that the credit is a reasonable share of the risk, and make sure no earnings date falls before expiration. Write the exit plan before you place the order.

A short put with a delta of 0.20 gets described as having an 80% chance of expiring worthless, and plenty of strike choices start and end with that one number. It’s a rough reading. Delta measures how much the option’s price moves for a $1 move in the stock, and it only approximates the probability of finishing in the money under the pricing model’s assumptions, which include a volatility figure that may be wrong and say nothing about the chance of the stock touching your strike on the way. Start somewhere else. Start with the chart and your account.

Which direction are you trading?

Decide what you expect the stock not to do. Staying above a level calls for a bull put spread, sold below it. Staying under one calls for a bear call spread, sold above it. Either way you collect the credit up front. You keep it all if the stock stays on the right side of the short strike.

Where does the short strike go?

Beyond a level you expect to hold. Take a hypothetical stock near $100. The chart shows repeated support around $96. A short strike at $95 sits just under that support, so the stock has to break the level before the spread is in trouble. The 98 put would pay more. It would also be caught by an ordinary pullback, the kind that dips a couple of dollars and recovers within days without ever testing the support that the whole trade was built around.

Delta still has a use here, as a cross-check. Read the short put’s delta off the chain once you’ve picked the strike from the chart. A reading that implies a high chance of finishing in the money tells you the market sees your support level as weaker than you do, or expects a bigger move than the chart suggests, and either is a reason to look again before selling. Treat it as a rough gauge. The model behind it assumes a single volatility and a smooth path, and real stocks gap.

How wide should it be?

Width sets the dollar risk. Sell the 95 put at $2.10. Buy the 90 put at $0.90.

The most you can lose on one spread is $380. It happens if the stock closes at or below $90 at expiration. Now size it against the account. Say it holds $50,000. Your rule risks 1% per trade, so the limit is $500. One spread fits at $380. Two would be $760, which breaks the rule, so a trader who wants more exposure has to use a narrower width or accept a single contract.

The vertical spread width lesson compares widths on the same short strike in more detail.

Is the credit worth the risk?

Compare the credit with what you stand to lose.

You risk $3.80 to make $1.20. A spread paying 31.6% of its risk needs to win often to come out ahead over many trades, and the break-even win rate on these numbers is the maximum loss divided by the sum of the loss and the credit, $3.80 / $5.00 = 76%, before commissions and before any early closes change the actual amounts won and lost. Moving the short strike further out lowers the credit and raises that required win rate. Moving it closer does the reverse, with more chance of the stock reaching it.

What dates fall before expiration?

Check the calendar. An earnings release between now and expiration can gap the stock straight past both strikes overnight, and no stop can prevent that, so a spread whose loss would be fine on a slow drift can hit its maximum at the open. The earnings gap loss calculator shows what a gap would do to the underlying position. If the chain lists an expiration that falls before the report, that date keeps the event out of the trade.

What is the exit plan?

Write it before the order goes in. A hypothetical plan might read: buy the spread back at $0.60, which keeps half the credit; close it if the stock closes below $95; close it no later than a week before expiration regardless. Those numbers are an example. What matters is that each line is fixed in advance. A losing spread invites a fresh excuse every day.

Keep both legs as one position. Adding extra short options for more credit turns a defined-risk spread into something else, as a ratio spread hides a naked option in the fine print explains. The after the covered call course covers spreads step by step, and the options hub has the rest.
