0DTE means options that expire the same day they're traded. Cashflow Engine backtests 0DTE SPX strategies at scale, then helps you build, stress-test and track a portfolio of them — this is that whole workflow, narrated, start to finish.

Why one strategy is never enough.
Same money. 14x less drawdown.
One strategy made +313.0% on paper — but only by stacking 15 contracts of a single idea into the same $100,000 budget, with a worst stretch of -27.6%. All 14 strategies together, same $100,000 budget, made +133.5% — with a worst stretch of only -1.9%.
“The Holy Grail of investing.” — Ray Dalio
Start: one iron-condor-style strategy
Contracts per strategy: 15
One strategy, sized up to 15 contracts to use the full $100,000 budget: it made +313.0%, but its worst stretch alone cost -27.6% — nothing was there to cushion it.

Backtested, 52 weeks to Oct 2026. Same $100,000 margin budget at every step, whole contracts. Hypothetical, selected on the same window it’s measured on. Not a forecast. Not financial advice. Ray Dalio and Bridgewater Associates are not affiliated with and do not endorse Cashflow Engine.
Most backtests flatter you.
Pick a date. That's walk-forward testing: the Hunter builds a portfolio using only the data up to that day — then you see what happened after.
“Nothing after this date was read. That makes the run repeatable, not predictive: it is still selection, not a holdout.” Four real Hunter searches on our own account, each using only data up to its date. Returns are % of $35,000 set aside for the trades. Backtested results. Not a forecast. Not financial advice.
That's tested on data it never saw.
See what it costs to get that kind of discipline on your own portfolio.
Browse. Build. Hunt. Stress-test. Export.
We ran the backtests. You run the portfolio.
A strategy is one exact, repeatable trade: entry time, width, premium, stop. Browse 275,000+ backtested variants and filter them in seconds.
Meet the Hunter.
Picking a handful of strategies that work well together is a search problem: thousands of candidates, astronomically many combinations. The Hunter does the search under your rules and returns a few portfolios that pass every one of them — candidates to inspect, not recommendations.
Premium, return, drawdown, correlation limits.
Every candidate, checked against your rules.
A few portfolios that passed everything.

Build it for real — start your 14-day free trialWho it's for.
Built for you if:
- You’ve sold option premium before — credit spreads and iron condors are familiar ground, not new concepts
- You have $25k+ in buying power as a minimum — $100k+ is where the math really starts working for you
- You want strategies specified precisely enough to measure — entry time, width, stop loss and premium pinned down, across MEIC, METF, ratio spreads and more
- You'd rather spend minutes than hours each week optimizing and updating your portfolio
- You'd rather read a distribution than a guru thread
Not for you if:
- You're still learning what an iron condor is
- You want signals, alerts, or someone to tell you what to trade
- You expect promised returns — we publish statistics, not promises
“Your portfolio did good in the backtest — ok — but will it survive the Monte Carlo sim? How's the correlation? Which strategy is a gem and which can go? Makes a hell of a difference.”
“A fantastic database that provides a high-quality, backtest-driven foundation for selecting options strategies.”
“A knowledgeable and experienced guide — his optimization efforts for data-driven strategy selection are truly groundbreaking.”
“Comprehensive, detailed, and analytically presented backtest evaluations. Risk simulations and detailed strategy development — thoroughly testing your own ideas and refining them based on data.”
“I'm a regular user and, as a professional, more than impressed.”
“His know-how and experience show in every detail. It has helped me trade in a more structured, data-driven way.”
“An exceptional combination of usability, precise analysis, and fast results.”
“An extremely motivated and helpful community where even newbies are welcomed and supported.”
“Right from onboarding you're guided professionally and warmly, and you can reach the team and other members anytime for quick, competent support.”

Built by a trader who couldn't stop backtesting.
I'm Thomas — engineer, options trader, and the person who answers when you ask a question. Not a marketing team. I built the engine because I refused to trade strategies I couldn't measure. Every number in the catalog comes from the same pipeline I use for my own research. Math beats emotions — that's the whole philosophy.
— Thomas, Founder & Portfolio Engineer

Questions
How are the trades actually automated?
The engine never places trades. You export the portfolio you want to run and execute it on an automation platform you already use: OptionsApp (which automates via Interactive Brokers, CapTrader and other IBKR-based brokers), Option Omega (Charles Schwab, tastytrade, Tradier), TradeSteward, or Trade Automation Toolbox. Your account, your broker, your decision — we are where the export comes from, not where the order goes.
What exactly is in the strategy database?
275,000+ backtested strategy variants on SPX 0DTE: Multiple Entry Iron Condors (MEIC), METF trend-following, ratio spreads and more. Every variant is scored the same way on the same data, which is the point — it makes a comparison between any two of them mean something. Think of it as options backtesting done once, centrally, at a scale no single trader can run alone.
How current is the data?
We backtest day and night to keep the catalog current, and the whole grid is re-scored every week on second-level data. You are never choosing from a snapshot someone took months ago.
Do I need to know MEIC or METF already?
It helps, honestly. This is built for traders who already sell option premium — if credit spreads and iron condors are familiar ground, you will be at home. It is an analytics workbench, not a first options course: we do not teach the strategies from scratch.
What account size does this make sense for?
$25k in buying power is the sensible minimum. To really be ahead of the game and let the math work out, though, $100k+ is what we would recommend — that is where spreading capital across several uncorrelated strategies becomes practical rather than theoretical.
Can I bring my own strategies or backtests?
Yes. Import your own strategies and backtests, analyze them with the same KPI engine that scores the catalog, and compare them side by side against it. Same scoring, same charts, no special-casing.
Why is a payment method required for the free trial?
Honestly: to keep the community clean. A card on file filters out drive-by signups and scammers, so the private Discord stays a room of committed traders. You are not charged during the 14 days — cancel before the trial ends and you pay nothing. And the Discord access you gain is yours for life, even if you cancel.
Is this financial advice?
No. Cashflow Engine is analytics software. We publish statistics — backtest results, distributions, correlations — and you make every decision about what to trade. We do not give recommendations and we do not promise returns.
