Intraday Structure & 0DTE with Market Pulse

What Market Pulse Tracks

Market Pulse is MarketOptix's real-time monitoring tool. While the Price Levels gives you a snapshot, Market Pulse shows you how that snapshot is evolving throughout the session.

The tool tracks three things simultaneously:

Regime status — Is net GEX positive or negative right now? Has it changed since the open? The regime timeline shows you exactly when transitions happened.

Intraday gamma shifts — How are structural levels (CW, PW, ZG) moving during the session? Walls can shift 5-10 points intraday as options are traded and 0DTE positioning evolves.

Flow data — Net GEX, DEX, and VEX changes in real time. Is positive gamma building (structure strengthening) or eroding (structure weakening)?

For day traders and 0DTE players, Market Pulse is essential. The structural landscape at 10:30 AM can look completely different from what you saw at 9:30 AM — especially on days with heavy 0DTE activity.

0DTE Structure: How It Forms and Shifts

Same-day expiration options (0DTE) have extremely high gamma — an at-the-money 0DTE option can have 10x the gamma of one expiring in 30 days. This means modest OI at a single strike can create significant intraday structural pressure.

At market open, 0DTE options are listed across a range of strikes. As traders buy and sell throughout the morning, open interest builds — and with it, gamma exposure.

By mid-morning (10:30-11:00 AM), a recognizable 0DTE structure usually forms: call gamma building above spot (intraday resistance) and put gamma below (intraday support). This overlays on top of the multi-day structure from weekly and monthly options.

Market Pulse separates 0DTE structure from longer-dated structure, so you can see both layers independently. The 0DTE layer tells you about today's intraday dynamics. The longer-dated layer tells you about the bigger structural picture.

Reading Regime Transitions in Real Time

The most important moments in a trading day are regime transitions — when net GEX flips sign. Market Pulse's regime timeline makes these visible.

A transition from positive to negative often looks like this: price drifts lower through the morning, eroding positive GEX. At some point, it crosses below the zero gamma line. Market Pulse flags the transition. Suddenly, selling pressure that was being absorbed starts getting amplified. The intraday range expands.

A transition from negative to positive is the reverse: a selloff reaches a level with enough positive gamma (often the put wall) that dealer buying overwhelms the move. Price stabilizes and Market Pulse flags the regime recovery.

Scenario: SPY opens at 585 in positive gamma. By 10:30 AM, it's drifted to 581. Market Pulse shows GEX declining but still positive. At 11:15, SPY hits 579 and Market Pulse flags a regime flip — ZG was at 580. Now you know: the cushion is gone. Dips won't be bought by dealers anymore. If you're long, this is your signal to tighten stops or exit.

The 0DTE Trading Workflow

Here's how to use Market Pulse for intraday and 0DTE trading:

Pre-market (9:00-9:30): Check the Price Levels for multi-day structure. Note CW, PW, ZG. This is your "big picture" framework for the day.

First 30 minutes (9:30-10:00): Let 0DTE structure build. Market Pulse will show the intraday gamma accumulating. Don't trade the structure until it's established.

Mid-morning (10:00-11:00): The 0DTE picture is clear. Market Pulse shows intraday levels. Combine these with the multi-day levels from pre-market for the full picture.

Afternoon (2:00-4:00): 0DTE gamma intensifies as expiration approaches. Pinning effects become extreme. Market Pulse shows whether price is gravitating toward a high-gamma strike or breaking free.

Key principle: 0DTE structure resets daily. Yesterday's levels don't carry forward. Market Pulse gives you today's evolving picture — treat each session as its own structural story.
