One-second crypto charts, free.
Exact one-second candles are free on Basis for venues that expose sufficient public trade data. Each candle is reconstructed from the trades inside that second, not divided or interpolated from a one-minute bar, and no account is required to open it.
What you get
- Open from the first trade, high and low from the real extremes, and close from the final trade of each second
- Volume, quote volume, trade count and taker-buy volume summed from the public tape
- Quiet seconds carried forward with zero invented volume so the time axis remains regular
- Late trade handling that folds a delayed print back into the correct second instead of dropping it
- Live continuation from the exchange trade stream rather than a visual animation between slower bars
- Compatibility with indicators and order-flow tools where the selected venue supports the required data
Why this is usually paid for
Sub-minute charting is often reserved for an expensive plan because it is easy to market as professional and expensive to serve as deep prebuilt history. The smaller the interval, the more bars and live updates a chart must process, so providers use resolution as both a cost boundary and an upgrade trigger.
Basis takes a narrower and more honest approach. It builds one-second bars locally from the public tape where a venue makes that possible. That removes the need to sell a separate one-second data product, but it also means availability and historical depth depend on the exchange rather than on a promise that every venue can do the same thing.
A one-second chart is not a better directional model simply because it contains more bars. It is a microstructure view for examining the response around a level chosen on a slower chart. Using it to discover the entire trade creates far more noise, more false patterns and more temptation to react to spread-level movement.
How to use it
- 1
Choose a supported venue
Open a Binance market in the terminal and select 1s from the timeframe row. Basis disables the interval on venues that cannot supply the underlying trade stream rather than displaying an approximation under the same label.
- 2
Select the level on a slower chart
Mark support, resistance or the planned entry on a higher timeframe first. The one-second view should answer how price is responding at that location, not where the important location is.
- 3
Read movement with participation
Compare the size of the price change with volume, trade count and taker activity. A quick move with little participation and a move sustained by repeated aggressive trades may print similar candles but describe different liquidity conditions.
- 4
Return to structure after execution
Once the immediate entry or rejection has been assessed, move back to the timeframe that defined the setup. Staying on one-second candles encourages management decisions based on noise that was never part of the original invalidation.
Questions
Are the one-second candles real or estimated?+
They are reconstructed from real public trade prints. Basis assigns every trade to its exchange timestamp second, uses the first and last trades for open and close, preserves the actual high and low, and sums the traded volume. It does not split a one-minute candle into sixty invented shapes.
Why is the 1s timeframe unavailable on some exchanges?+
A truthful one-second candle needs either a native one-second endpoint or enough public trades to rebuild it. Some venues do not provide historical one-second bars and cannot provide the same coverage through their public interfaces, so Basis disables the option instead of presenting lower-quality data as equivalent.
How much one-second history is available?+
One-second history is naturally shallower than minute or hourly history because it contains sixty times as many bars and often has to be reconstructed from trades. Basis is designed for recent microstructure and live continuation at this interval, not for pretending that years of tick history are freely available.
Should a scalp strategy use only a one-second chart?+
No. A one-second chart is best used to refine execution around a level and scenario defined on slower timeframes. Regime, structural support, trend and reasonable invalidation are usually clearer above one second; the faster chart then shows whether the expected response is actually arriving.
