Time and sales, free.
The trade tape is free on Basis, streaming live with no account and no trial. Every print carries the aggressor side from the venue itself, so you are reading who lifted and who hit rather than guessing from colour.
What you get
- A rolling list of received trades, with price, size and the side that crossed the spread
- Aggressor flags taken from the venue rather than inferred from an uptick rule
- Feed-aware prints: Binance spot aggregate trades and USD-M live trades, without pretending a row identifies a trader
- A running count of exactly how many trades have been loaded, so you know what the numbers are built on
- Executed-volume context beside the footprint: compare the same venue, market and time window, accounting for loading and aggregation differences
Why this is usually paid for
Time and sales is old technology and it is still behind a login almost everywhere, because it is bundled with level-two entitlements rather than priced on its own. In equities that bundling reflects a real exchange fee. In crypto it reflects nothing but habit — the venues publish the tape on a public websocket to anyone who asks.
So Basis asks, in your browser, and renders what comes back. There is no per-seat feed cost behind the tape, and a page that charged for it would be charging for the connection rather than the data.
How to use it
- 1
Open the tape
The button below opens the terminal. In the Order Flow panel, choose the Time and Sales tab. Prints start arriving immediately; nothing needs configuring and there is no symbol to enter separately, since the tape follows the chart.
- 2
Read size before you read direction
Compare large prints with the recent flow baseline and the price response. A large trade deserves attention, but its size does not reveal the trader, their wider position or whether the execution was a hedge.

Watch the tape against a level
The tape is most informative when you already have a price in mind. Put a level on the chart, then watch what happens on the tape as price reaches it: heavy prints that fail to move price are a different event from thin prints that sail through.

Use it to check what the ladder promised
Compare a visible wall with executions near its price. Heavy prints while displayed size holds may suggest replenishment; a disappearing wall with little observed trading may suggest pulling. Sampling, feed gaps and order changes limit the inference — neither proves trader intent.
Questions
Is the buy and sell side on the tape real, or estimated?+
It is real. Every trade the venue publishes carries a flag saying whether the buyer or the seller was the aggressor — which side crossed the spread to get filled. Basis uses that flag directly rather than applying an uptick rule to guess, which is what tools without tape access have to do.
Do I need an account to see time and sales?+
No. The tape opens on a live market with no sign-up, no email and no trial period. The core time-and-sales view is free; the optional Founders membership adds separate research features.
Why are some prints much larger than any single order?+
Some feeds aggregate executions, while others publish individual fills. Basis uses Binance aggregate trades for spot and live trades for USD-M; historical loading can also use aggregate trades. A print is a feed record, not proof of one trader’s complete order or position.
How far back does the tape go?+
The live tape is a rolling window of recent prints rather than a full archive. Historical trade data does get loaded for the footprint chart when you pan to an older period, but the Time and Sales list itself is built for watching the market now, not for auditing last Tuesday.
Which markets does the tape cover?+
Binance spot and USD-M perpetual markets. Perpetuals are where most crypto order flow actually happens, and spot and perpetual are separate books with separate tape, so read the one you intend to trade rather than assuming they agree.
