0DTE SPX trade strategies and the options framework behind them.

Why a system

Day trading index options sits at the extreme edge of the difficulty curve: a small minority of traders achieve consistent profitability. Why? Because they lack a proven system built on real results.

Over the last 10 years, I have refined a specific system. It is not a magic indicator. It is a set of filters designed to keep you out of bad trades and size you into good ones. Five inputs, weighed against each other before any SPX position is taken:

The trigger: 10-minute 8 EMA

In a fast market like SPX 0DTE, simple moving averages create fatal lag. EMAs (Exponential Moving Averages) solve this by applying a weighted multiplier to the most recent data points, making them far more responsive to sudden volatility.

Next, the timeframe: a 5-minute chart creates too much noise (“whipsaws”). Instead, we use the 8 EMA specifically on the 10-minute chart.

We do not enter just because price touches the line.

The structure: supply and demand levels

The EMA is just a line. To trade successfully, you need a map. We call these Levels (supply and demand).

Demand zone

An area where buyers previously stepped in with aggression. When price returns here, we look for bounces.

Supply zone

An area where sellers previously took control. When price returns here, we look for rejections.

We do not guess. We look to execute trades when price interacts with these specific zones, and at no other time. We do not trade in “no man’s land” between levels.

The filter: VIX divergence

Most traders ignore the VIX or treat it as a static number. In Alpha Pod, we treat the VIX as a second chart that we trade against. The VIX has its own support and resistance levels. We look for one specific red flag:

The setup: convergence

The highest-probability trade occurs when our structural data (the levels) aligns with our momentum trigger (the 8 EMA). We call this Convergence.

When price reclaims a Key Level and reclaims the 8 EMA simultaneously, the probability of a sustained move increases drastically.

Risk management: volatility-adjusted sizing

Making money is hard; keeping it is harder. The number one reason traders fail with SPX 0DTE is that they do not respect the volatility.

Standard stop losses (selling if down 20%, say) often fail in SPX. The market noise is too loud: a single wick can stop you out right before the trade moves in your favor. Instead, we use position sizing as our primary risk tool.

The Alpha Pod approach

We size our trades small enough that even if the contract goes to zero (a 100% loss), the portfolio survives to fight another day. This allows us to hold through the volatility and let the thesis play out, rather than getting shaken out by noise. The trade log shows the called size on every position.

The context: the flow behind the setups

The framework above is structure, momentum and risk. The fourth input the desk reads every session is institutional options flow: where size is actually positioning while price tests the levels. Raw flow is mostly noise; the desk runs it through the filter described in how to filter options flow and taught in the options flow course, and the terminal that automates that filter is Nightglass, built by this desk and scored in public. The fifth input, gamma exposure, has its own guide. For sizing a position against the day’s implied range, the expected move calculator does the arithmetic.
