Monthly Iron Condor on the SPY: How to Generate Recurring Income

The monthly Iron Condor on the SPY is probably the trade I repeat most in the year. It’s not the most exciting one or the one that will give you +700% in a week — it’s the one that works precisely because it’s boring. You sell a range when the market pays you well for it, with defined risk and clear management. If you run it well, it behaves like a business: consistent, predictable and scalable.

Why the SPY?

The SPY (the ETF that tracks the S&P 500) has some characteristics that make it ideal for this strategy:

• Brutal liquidity — the spreads are tiny and execution is impeccable
• Underlying bullish trend — historically it goes up, which helps keep the put leg far away
• Weekly and monthly expirations — you can choose exactly the term that suits you
• Predictable volatility — it rarely makes extreme moves without warning

And since it’s a US stock ETF, you have to keep in mind that these are American-style options — the counterparty can demand early assignment. Something to bear in mind although, if we manage the triggers well, it should never happen.

Before opening: market context

The first thing to look at before touching the options chain is the SPY chart. Is it ranging? Is there any key resistance or support too close? Is there an employment figure, a Fed meeting or an inflation reading coming that could move the market?

Here’s one of the keys: people want to trade every day, and there aren’t opportunities every day. I prefer to trade when the market makes it easy for me. If this month isn’t the time, I let it pass and look for a different kind of strategy.

Step-by-step construction in ProRealTime

We open the options chain in ProRealTime v13 and look for a monthly expiration between 30 and 45 days. Why these terms? Because theta works especially well in this range — neither so far that it doesn’t erode premium, nor so close that any move wipes you out.

Leg 1: Put credit spread (bearish side)

• We sell a put with a delta between 0.15 and 0.20 — this is the one that gives us the fat premium on the downside
• We buy a put further down as protection — in this example, $10 below the sold strike

Leg 2: Call credit spread (bullish side)

• We sell a call also with a delta between 0.15 and 0.20 — this gives us the premium on the upside
• We buy a call further up as protection — same $10 width above the sold strike

Result: we have a put credit spread on the downside and a call credit spread on the upside. That’s the Iron Condor — a defined range where we collect if the price stays inside.

A real example of the trade

Break-even and comfort zone

In ProRealTime’s risk analyzer we can see the two break-even points — one on the upside and one on the downside. What I always do is draw them directly on the SPY chart to have a visual of the comfort zone where I need the price to stay.

And if I also see that some resistance, moving average or relevant technical level falls too close to a strike, I can modify the strikes before sending the order to feel more comfortable.

Managing the position: this is where experience shows

Opening the Iron Condor is the easy part. The part that makes the difference is what you do once it’s open. And here you have to be very clear with the rules.

Profit-taking close trigger

If the trade reaches 70% of the credit collected, I close it. I’m not interested in squeezing out the last cent — that’s precisely where there’s the greatest chance of an event ruining the trade. The rest is greed.

Why not wait until expiration? Because most of the premium has already been captured in the first weeks. That last 30% of the potential profit doesn’t justify the risk of keeping the position open for more days.

When the price approaches a strike: two approaches

I don’t wait for the SPY to reach one of the short strikes. I like to act earlier, and here I have two approaches depending on the situation:

When NOT to open an Iron Condor

There are months that simply aren’t suitable. The discipline of not trading is as important as the discipline of trading well:

• Expiration too long or too short for the current cycle
• An important macro event nearby (employment data, Fed meetings, inflation)
• Sky-high implied volatility — careful, if they pay a lot of premium it’s because the market expects a big move
• A strong trend with no signs of exhaustion
• A market in free fall — an Iron Condor isn’t the instrument for that situation

I don’t care if this month isn’t the time. Let’s look at other types of strategies, other things we can do, but this one we set aside for the following month.

The philosophy of the recurring business

To many people, collecting $250 a month with an Iron Condor may seem like little. But you have to put things in perspective:

• It’s recurring — you repeat it every month the conditions are favorable
• It’s scalable — you can increase the number of contracts as your account grows
• The ROI on margin is interesting — the broker only asks you for the margin of one side, not both
• Probability is on your side — with deltas of 0.15-0.20, statistically you win more months than you lose

Here I’m not looking for a +700% trade. I’m looking for consistency and repetition. And since consistency is boring, many people don’t do it — and that’s precisely why it works.
