Pre Market

Overview​

The Pre Market profile is your first look at the market before the regular session opens. It lays out every ticker by sector and industry, sizes each box by market capitalization, and colors it by the pre-market price change, so gaps and early pressure stand out immediately.

Because the largest companies get the largest boxes, this view answers the question that matters most before the bell: is the early move being carried by the market's heavyweights, or is it limited to smaller names on the fringes?

info

This profile activates automatically in Heat Maps during pre-market hours, so opening the page in the morning always starts you here. It updates in real time as pre-market trading develops.

Strategy Focus​

  • Read the early tone of the market before the regular session begins
  • Spot sectors and industries gapping as a group rather than one ticker at a time
  • Judge whether mega caps or small names are driving the pre-market move
  • Find individual gappers worth a closer look on the chart
  • Build a pre-open watchlist by right-clicking boxes to add them
  • Compare the pre-market picture against yesterday's leaders for continuation or reversal clues

Map Configuration​

  • Main Category: Sectors
  • Sub Category: Industries
  • Box Size: Market Capitalization ($)
  • Box Color: Change Pre Market (%)

Metrics Behind the Map​

  • Market Capitalization ($): The total dollar value of a company's outstanding shares. Sizing by market cap weights the map the way the indexes are weighted, so the visual impression matches how much each stock actually moves the market.
  • Change Pre Market (%): The percentage difference between the last pre-market price and the previous day's close. Green shades mark gainers, red shades mark decliners, and stronger moves show in deeper colors.

Practical Use Cases​

  • Scan the map at the start of your morning routine to understand the session before it opens
  • Zoom into a gapping industry and click boxes to review the charts behind the move
  • Click a group header to open a whole industry in Multi-Charts for a fast pre-open review
  • Search for a ticker you hold to check its pre-market move in context, not in isolation
  • Compare this view with Advancing/Declining (Pre) to confirm how broad the early move is
