Tools · BTI

Block Trade Indicator

The BTI is a live feed of large prints, split into cards. Each card has its own name, minimum size, minimum price, tickers, colours and columns. Run a small-size card to catch early activity, a large-size card for the big blocks, and a card for only your watchlist.

Five BTI cards side by side named 50K, 100K, 400K, 1M+ and Stock 5 — Five stock cards. The right rail holds the add-card button and the view switcher.

Reading a card

Each row is one print: Time (ET), Ticker, Price, Size and Bid Ask. The Bid Ask column shows where the trade printed against the quote at that moment:

Below BidAt BidBetweenAt AskAbove Ask

Seller more aggressive on the left, buyer more aggressive on the right. These are the default colours; you can change them per card.

Options cards

On accounts with the options tools, cards can follow option trades instead. Option preferences add Min premium, Min contracts, UOA only and Buy/Sell only, and columns for Contract, Side, Premium, Sentiment, Fill and DTE.

Edit preferences for an option card — An option card set to UOA trades of at least $1,000 premium and 10 contracts.

Views

The right rail switches between Stock, Stock Grid, Options, Options Grid, Combined and Combined Grid. Grid views tile cards in rows, which suits wide or tall monitors. The + at the top of the rail adds a card to the current view.
