Heatmap FAQ

The Heatmap is an advanced visual exploration tool for options money flow on stocks. It uses an interactive treemap where each tile represents a stock (or group of stocks) and its size reflects the total premium traded.

Key differences from the Dashboard:

• The Dashboard shows a high-level overview with 20 tiles max per pane, grouped by sector or industry.
• The Heatmap shows up to 50 tiles and supports multi-level drill-down — you can click through sectors → tickers → strike/expiry breakdowns.
• The Heatmap has a full filter drawer (like the Flow page) with moneyness, trade type, algo score, and more.
• The Heatmap lets you switch between Stocks and ETFs.

Each tile in the treemap represents a stock, sector, or industry depending on your current drill level.

Tile sizing: Tile area is proportional to the total premium traded. Larger tiles = more options activity.

Tile colors:

• Green tiles = Bullish flow (calls bought, puts sold)
• Red tiles = Bearish flow (puts bought, calls sold)
• Darker/brighter shades indicate higher premium amounts.

Tile labels: Each tile shows its name and the dollar premium amount (e.g., "NVDA $12.5M").

Hover: Hovering over a tile shows a tooltip with the ticker name, premium amount, and its share of the total flow.

Click: Clicking a tile drills down to the next level of detail.

The Heatmap supports 3 levels of drill-down:

Level 1 (Top): All Sectors or All Industries — the top-level treemap tiles.

Level 2: Click a sector or industry tile → the treemap updates to show individual stock tickers within that group.

Level 3: Click a specific ticker → the treemap breaks down that ticker's flow by Strike Price, Expiration Date, or Both.

Navigation: A breadcrumb appears above the treemap showing your current path (e.g., "Sectors > Technology > NVDA"). You can:

• Click any breadcrumb segment to jump back to that level.
• Click the X on the deepest level to go back one step.
• At Level 3, clicking tiles has no effect — you've reached the deepest view.

You can also use the Sector/Industry/Ticker dropdowns in the filter drawer to jump directly to any level without clicking through.

The top row displays three key metrics:

Bullish Premium — Total dollar amount of bullish options flow (calls bought + puts sold).

Bearish Premium — Total dollar amount of bearish options flow (puts bought + calls sold).

Bias — The dominant sentiment as a percentage. Examples:

• Bullish 67% means bullish flow is 67% of the total.
• Bearish 60% means bearish flow is 60% of the total.
• Neutral means flow is evenly split.

Below these stats, a gradient bar visually shows the bullish-vs-bearish split: the green portion represents bullish flow and the red portion represents bearish flow, with dollar amounts on each end.

Use the Sector / Industry toggle at the top of the Heatmap:

• Sector groups stocks by broad sector (e.g., Technology, Healthcare, Energy).
• Industry groups stocks by specific industry (e.g., Semiconductors, Software, Biotech).

Switching the toggle resets the drill-down to the top level and re-fetches data. You can also select a specific sector or industry directly from the filter drawer dropdowns.

The Heatmap supports both Stocks and ETFs. Switch between them using the Instrument Type toggle in the filter drawer (STOCK / ETF).

When in ETF mode:

• Sector/Industry grouping is bypassed — tiles show ETF tickers directly at the top level.
• Clicking an ETF tile drills into that ticker's strike/expiration breakdown.
• The breadcrumb shows the ETF ticker name.

When switching from ETF back to Stock mode, the drill-down resets to the top level.

The filter drawer (opened via the filter icon) provides the same power as the Flow page:

Quick Filters (top row):

• Sector / Industry toggle
• Instrument Type: STOCK / ETF

Dropdown Filters:

• Sector — Jump directly to a specific sector
• Industry — Jump directly to a specific industry
• Ticker — Jump directly to a specific ticker (bypasses sector/industry)

Option Filters:

• Moneyness: ALL / ITM / NTM / OTM
• Action: ALL / BOUGHT / SOLD
• Trade Type: ALL / SWEEP / BLOCK

Toggles:

• Only Repeats — Show only repeated trades
• Volume > OI — Show only when volume exceeds open interest

Sliders & Ranges:

• Algo Score — Normal / High / Higher / Highest
• Strike Price Range — Min and max strike prices
• Expiration Date Range — Filter by expiration dates
• Transaction Date Range — Filter by when trades occurred

Use Reset to clear all filters and return to the default view.

When you drill down to a specific ticker (Level 3), a secondary toggle appears next to the ticker name in the breadcrumb:

• Strike Price — Tiles show individual strike prices for that ticker's options flow.
• Expiration — Tiles show individual expiration dates.
• Both — Tiles show a combined view with strike and expiration labels.

The default is Both when you first reach Level 3. Changing this toggle re-fetches the data for the current ticker without leaving the drill-down view.

Tile size reflects the total premium (dollar value) of options flow for that stock or group.

Larger tiles = more money flowing through that stock's options. Smaller tiles = less activity.

Tile sizes are calculated relative to the global total (both bullish + bearish combined), so a tile with $100M premium is visibly larger than one with $25M, regardless of which pane (bullish or bearish) it appears in.

On mobile, fewer tiles are shown (20 instead of 50) to keep them large enough for readable labels.

When you hover over any tile, a tooltip appears showing:

1. Ticker / Group name — The stock ticker, sector name, or other label.
2. Premium amount — The total dollar value of options flow (e.g., $12.5M).
3. Share percentage — What percentage of the total flow this tile represents.

On mobile, tap a tile to see the tooltip briefly before the drill-down action triggers.

The breadcrumb above the treemap shows your current position:

• Sectors > Technology > NVDA means you're viewing NVDA's flow breakdown within the Technology sector.

To go back:

• Click Technology in the breadcrumb to return to the Technology sector's ticker list.
• Click Sectors to return to the top-level view of all sectors.
• Click the X button next to the deepest breadcrumb segment to go back one step.

You can also use the Sector / Industry / Ticker dropdowns in the filter drawer to jump to any level directly.
