Unusually large trades land on one big chart. Each one is ranked against its ticker's own history since 2016, so you can tell at a glance how rare it is.
Data, not advice. Market data delayed 15 minutes. History starts in January 2016, or on a ticker's first covered day if later.

The tape is a running list of unusually large trades across the stocks and ETFs we cover. Each row shows the ticker, the dollars, the rank and where it traded. Select a row and the chart opens at that moment.
Prints arrive 15 minutes after they trade. Each row shows the time it traded.
Prints arrive as they are reported to us. Each row shows the time it traded.
Open the tapeA $40 million trade is routine in one stock and the #1 Print in another. So BigTape gives every big print two numbers. The first is its size in dollars. The second is its rank among that ticker's own trades since 2016.
Every mark on the chart follows one rule. Shape is the kind of trade. Fill is where it traded. Size and number are the rank.
In the light and dark themes, Exchange prints are solid blue discs and Dark prints are hollow pink rings. Colors change with the theme. Shapes and fills never do.
No mark points up or down, and none uses the candle colors. A print's side is unknown, so the chart never hints at one.
Some trades happen off-exchange, at private venues or inside brokers. BigTape calls them Dark. When heavy Dark dollar volume builds up in one price zone, the chart shades it as a Dark Level, ranked all-time for the ticker by its Dark dollars since 2016. The chart draws the top five levels in the price range you're looking at; you can pick from Show 3 to Show 20, or turn them off.
A Dark Level records where trading happened. It says nothing about where price goes next.
Your favorites sit beside the chart, each with today's change and the all-time rank of its last ranked print. Under them sit SPY, QQQ, IWM, DIA and the 11 sector ETFs. Select any row and the same chart switches to it, with your layout kept.
A badge like #4 is the all-time rank (since 2016) of the ticker's most recent ranked print, however long ago it landed. A small New tag means a ranked print landed today.
Compare draws a ticker and its sector ETF on one chart, both measured from the same start.
Step away for an hour or a weekend. When you come back, one card lists what changed on your tickers, biggest first. Select an item and the chart jumps to that moment.
Tell BigTape what to watch for, like a New #1 Print on any of your favorites. When an alert fires, one tap opens the chart at that moment, with the print and the rule that matched.
Alerts use the same data as the chart, so they arrive at least 15 minutes after the trade. Each alert shows when the trade happened and when we sent it.

Alerts can arrive late or not at all. Information only, not a recommendation to trade.
A chip on every screen says how fresh the data is. If updates stop, it says so and shows the last update. If nothing unusual happened, it says that too.
Every trade has a buyer and a seller. Trade reports don't say which side started it, so BigTape never gives a print a side or a direction. It never tells you what to trade, either.
BigTape covers U.S.-listed stocks and ETFs. Trade history starts in January 2016, or on a ticker's first covered day if later.
