Search "credit spread tracker" and the options results are a thin slice of what comes back: mostly Etsy spreadsheet listings, an Excel add-in or two, and a screener that finds spreads without ever tracking one. If you sell bull put spreads and bear call spreads, almost none of it is actually a tracker.
The structural problem is simple. A credit spread is two legs opened together for one net credit. You sold one strike and bought a cheaper one below it, and the number that governs the trade is what you netted — not what each leg did on its own. Generic options tools want to record those as two independent trades, each with its own entry price, exit price, and P&L line. Reassembling them into one coherent position is left to you, every single time.
The risk side is worse. Your maximum risk on a vertical is the strike width minus the credit you took in. Your maximum reward is the credit itself. Those two numbers define the whole trade, and they're precisely the two a generic tracker can't produce, because it has no idea the legs belong to each other.
So the question you need answered stops being "did this fill make money?" It becomes "what am I short right now, how much collateral is each position genuinely holding, and what has this book paid me?" That's a tracking problem — and it's why spread sellers keep ending up back in a spreadsheet.
Before comparing anything, here's the checklist. Not for finding spreads to sell — purely for keeping an honest record of the ones you already have on.
You opened for a single credit. The tracker should hold that as one number on one position, with the two legs underneath as detail you can expand — not arithmetic you redo mentally every time you check in.
Width minus credit on one side, credit on the other. Both are known the moment you open, and they're the entire reason you chose a defined-risk structure over a naked short — so they belong on the face of the position, not in a calculator.
A ten-wide put spread doesn't tie up the full value of the short strike. It ties up the width minus the credit. Any screen reporting your committed capital as though you'd sold that leg uncovered is overstating what you have at work by an enormous margin, and the distortion compounds across every open position.
Rolling a tested spread out in time, or down and out for more credit, is routine. Every roll adds a closing debit and an opening credit to the same position, and a tracker worth using carries a running net credit through all of it. This is exactly where hand-built sheets start drifting.
What has this underlying actually paid you over a quarter of selling spreads on it, and what has the whole book collected? Neither should require adding up two dozen individually closed option lines.
Most spread sellers also run cash-secured puts or covered calls somewhere in the account. Needing a second app for that half means neither app shows you a complete picture.
An iron condor is just two credit spreads on the same underlying and expiration, so anything that passes this test passes the condor test too — we ran through that version of the checklist in the best iron condor tracker apps for options sellers.
Log the position, not the fills. That's the whole discipline in one sentence, and it's what separates a record you can trade against from a pile of receipts. Here's what goes on the position the day you open it:
One 10-wide put spread, opened for a net credit of $1.40.
Now roll it: pay $2.10 to close, take $2.55 to open the replacement. Running net credit is $1.40 − $2.10 + $2.55 = $1.85. Against the same 10-wide structure, remaining max risk is $815 and remaining max reward is $185. Neither matches what you wrote down on day one — and the day-one numbers are what most tools are still showing you.
That roll is the moment tracking either holds together or quietly falls apart. Two entries, one position, one running total. Log the closing debit and the opening credit against the same spread rather than closing the book on trade one and starting a fresh trade two, and every derived number stays honest. Break the chain and you're managing against a credit you no longer have. There's a walkthrough of this in practice in the SPX credit spread and iron condor tracking demo.
Bear call spreads work identically with the signs flipped — short the lower call, long the higher one, same width-minus-credit math on the risk side.
One spread in a spreadsheet is fine — plenty of sellers start there and shouldn't feel bad about it. The trouble is that credit spread bookkeeping doesn't scale linearly. It scales by positions times legs times adjustments, and all three grow at once.
A spreadsheet has no built-in concept of "these two legs are one spread." You create that relationship by hand with formulas, and those formulas are the first thing to break. Roll a position and you're correcting the net-credit cell, the max-risk cell, and the collateral cell in the same pass. Miss one adjustment on a Friday afternoon and every total downstream is wrong — not visibly wrong, which would be fine, but quietly wrong, which is how you end up sizing the next trade off a number that stopped being true two weeks ago.
It's the same failure mode we've written about for the single-leg side in why covered call tracking spreadsheets break down, except spreads hit it roughly twice as fast, because every position is two legs instead of one and rolling is normal rather than occasional.
What replaces it is a tracker that stores each spread as one position with its own credit and defined-risk collateral, then aggregates those upward. The view you want across a multi-ticker book is short:
The threshold is the one every seller eventually hits: spreadsheets work until the bookkeeping takes longer than the trading. Past that line you want a purpose-built options portfolio tracker built for sellers, not a bigger sheet.
The options-side results for "credit spread tracker" fall into four buckets, and knowing which is which saves you a stack of abandoned trial accounts. Everything below is a category observation drawn from what these products publish about themselves.
Etsy and Gumroad are full of paid credit spread templates — a tidy pre-built layout with the width-minus-credit formula already wired in. Fine starting point, saves you an afternoon of cell work. But a template is static by nature: roll tracking, running net credit across adjustments, and cumulative P&L across tickers are still yours to build and maintain. You've bought a nicer version of the thing that was going to break.
Tools in the MarketXLS mold pull live option data and Greeks into Excel so you can model a spread before you place it — payoff at expiration, breakevens, probability figures. Real capability, aimed at analysis rather than record-keeping. You're modeling a spread, not maintaining a book of the twelve you already have on.
MarketChameleon and similar sites help you find candidates — filter by credit, width, implied volatility, expiration. Excellent for the selection half of the workflow and silent on the other half. A screener tells you what you could put on; it has no opinion about what you have on.
The smallest bucket and the only one organized around tracking. Multi-leg positions held as one unit, defined-risk collateral math, cost basis that survives rolls, and a portfolio roll-up across tickers. MyATMM sits here alongside a handful of other seller-focused tools.

Since this is our blog, here's the approach we built — not because it's the only reasonable one, but because it shows what we think a credit spread tracker has to get right.
If your current credit spread tracker is a template that needs three cells fixed every time you roll, or a position screen reporting collateral as though you'd sold the short leg naked, the numbers you're trading on aren't describing your actual book.
Pick something with a real free tier and put one live spread through it end to end. Open it for a credit, let it get tested, roll it out, then close it. Then ask the only question worth asking: do the running net credit and capital-at-risk figures the tool shows match what you'd compute yourself? If yes, it was built for spread sellers. If it just lists two unrelated option legs, you found a trade log.
