What Is SPX 0DTE Trading? A Data-Driven Strategy Using the Trend Spread Engine (TSE)

SPX 0DTE options have exploded in popularity—and behind the scenes, billions of dollars in premium are traded and expired every single day.

A large portion of that premium expires worthless.

The opportunity? Capture a piece of that flow in a structured, repeatable way.

A Real Example: TSE Performance Since Launch

Before getting into the mechanics, here’s what this looks like in practice.

From December 15 through April 17, trading just 1 spread at a time in a $10k account, the Trend Spread Engine (TSE) has produced a steady equity curve based on real trade logs.

Stats so far (since launch in Dec 2025):

• Win Rate: 90%
• Total Profit: $3,161
• Avg Win: $85
• Avg Loss: $275
• Expectancy: +$50 per spread

This is the core idea:

You don’t need perfect trades—you need consistent execution of a strategy with positive expectancy.

And because SPX options have massive liquidity, this approach can scale across different account sizes while maintaining the same structure.

Why SPX 0DTE Options Are So Popular

0DTE (zero days to expiration) options allow traders to:

• Trade daily income strategies
• Take advantage of rapid time decay (theta)
• Avoid overnight risk
• Focus purely on intraday price movement

But without structure, most traders struggle with:

• Entering at the wrong time
• Poor strike selection
• Trading against trend

That’s where a system like the TSE comes in.

The Core Idea: Capturing Expiring Premium Systematically

At its core, the strategy is simple:

Sell defined-risk credit spreads designed to benefit from options expiring worthless—using data, not guesswork.

Instead of predicting exact market direction, the TSE focuses on three variables that actually matter.

The 3 Pillars of the TSE Strategy

1. Trend

Trades are aligned with the current intraday trend using the SPX 5-minute chart.

No prediction. Just participation.

2. Strike Selection

Each trade uses probability-based strike selection, typically:

• Put Credit Spreads (bullish conditions)
• Call Credit Spreads (bearish conditions)

Strike deltas are chosen to balance:

• High win probability
• Controlled risk

3. Time of Day (The Real Edge)

Most traders ignore this.

Not all time windows perform equally in 0DTE trading.

Some 15-minute intervals consistently outperform others—and that edge shifts over time.

So instead of guessing…

We measure it.

How the Trend Spread Engine (TSE) Works

The TSE tracks every trade and ranks performance over a rolling 90-day window.

Each trading day:

• Alerts are generated every 15 minutes (10:00am–3:00pm ET)
• Trades follow real-time trend conditions
• Every alert is logged and tracked

Each week:

👉 Time intervals are ranked by performance over the past 90 days

This means going into the week, members already know:

Which time windows have historically produced the best results recently.

Why the Rolling 90-Day Window Matters

Markets change.

Instead of relying on outdated backtests, the TSE:

• Continuously adapts to current conditions
• Highlights top-performing intervals
• Filters out weaker time periods
• Keeps the strategy aligned with the present market

Real-Time Alerts + Built-In Performance Tracking

TSE alerts are posted daily inside the Alpha Crunching Discord.

Each alert includes:

• Trade direction (PCS or CCS)
• Strike selection
• Timestamp
• Chart context

Behind the scenes, every trade contributes to a dataset that tracks:

• Win rate
• Expectancy
• Time-of-day performance

A Different Way to Trade 0DTE

Most traders focus on:

• Indicators
• News
• Predictions

The TSE focuses on:

• When to trade
• Where to trade
• How to align with trend

That shift is what creates consistency over time.

Who This Strategy Is For

• Traders who want a repeatable system
• Those using defined-risk credit spreads
• People who don’t want to stare at charts all day
• Traders who prefer data over opinions

Final Thoughts

SPX 0DTE volume continues to grow—and so does the opportunity.

But the edge isn’t in predicting the market.

It’s in:

• Following a structured process
• Focusing on high-probability windows
• Executing consistently over time

The Trend Spread Engine was built to do exactly that.
