Building Your Edge with Signal Scanner

What Signal Scanner Does

You can't watch every ticker all day. Signal Scanner watches for you.

It monitors structural changes across your watchlist and the broader market, alerting you when something noteworthy happens. Instead of staring at gamma profiles waiting for a shift, you set up your alerts and let Signal Scanner do the surveillance.

The scanner tracks several categories of structural events:

Gamma flips — When a ticker's net GEX transitions from positive to negative (or vice versa). These regime changes are among the highest-value signals in market structure.

Wall shifts — When the call wall or put wall moves to a different strike. A shifting wall means the structural landscape is being redrawn.

Expected move breaks — When price moves beyond the options-implied expected range. This signals that the market's consensus is being challenged.

Unusual exposure — When a ticker's GEX, DEX, or VEX moves to an extreme percentile relative to its recent history.

Setting Up Your First Alerts

Start simple. You don't need to monitor everything — focus on the signals that matter for your trading style.

For swing traders: set gamma flip alerts on your core watchlist (10-20 names). When a name you follow shifts from positive to negative gamma, it's a signal that the structural environment is changing — and a potential trade setup.

For day traders: add wall shift and expected move break alerts on SPY, QQQ, and your intraday names. These real-time alerts tell you when the structural landscape is being redrawn during the session.

For options sellers: unusual exposure alerts are key. When VEX spikes to a 90th percentile reading, it means volatility sensitivity is extreme — which often precedes a vol event or creates a premium-selling opportunity.

Each alert is configurable. You can set the sensitivity (how large a change triggers an alert), the frequency (real-time, hourly, daily digest), and the delivery method (in-app, email, push notification).

Filtering and Custom Watchlists

Signal Scanner works best when you filter the noise. The market generates dozens of structural events every day — you only care about the ones relevant to your strategy.

Use watchlists to define your universe. Your "Core Holdings" list tracks your portfolio names. Your "Sector ETFs" list tracks XLK, XLF, XLE, etc. Your "0DTE" list tracks SPY, QQQ, IWM for intraday plays.

Combine watchlists with signal type filters. Maybe you want gamma flip alerts on all names, but only wall shift alerts on your core holdings. This keeps the signal-to-noise ratio high.

The scanner also has a "Market-Wide" mode that scans beyond your lists. Use this for discovery — finding names with structural setups you wouldn't have spotted otherwise. Then add them to a watchlist for ongoing monitoring.

Scenario: From Alert to Action

Here's how a Signal Scanner alert becomes a trade:

10:45 AM — Signal Scanner alerts you: "SPY put wall shifted from 575 to 570." The put wall just dropped 5 points.

You open the Price Levels. Sure enough, the structural floor has moved lower. SPY is at 580 with the put wall now at 570 instead of 575. The range just expanded on the downside.

You check Market Pulse. The regime is still positive but GEX has been declining since the open. The regime is weakening.

Your assessment: the structural floor just dropped, and the positive regime is fragile. If you're long, this is a warning — your support level just moved further away. You might tighten your stop from 574 to 577 (just above the old put wall, which no longer provides support).

Alternatively, if you were looking for a short entry, the weakening structure gives you confidence that a breakdown, if it happens, has room to run.

Without Signal Scanner, you might not have noticed the put wall shift until checking manually — by which time the opportunity or the risk management window could have passed.
