Velo uses TradingView's library to support seamless switching of coins and timeframes. Data updates live up to 10x per second and users may save up to 4 layouts that will persist across browser sessions. The chart can be taken into full screen, changed to line style, and broken into up to 16 panes.
The charting technology is provided by TradingView, a platform for traders and investors. It offers advanced charting tools where people driven by markets can track major upcoming events in the Economic calendar, chat, chart, and prepare for trades.
Indicators
Indicators may have additional functionality unlocked (including the ability to filter aggregated data by exchange) by mousing over their names and clicking the settings icon.
Indicators not prefixed by "<Velo>" are preset TradingView indicators and their definitions may be seen here.
Open Interest
Open interest is viewable in dollar or coin terms, and in the form of candlesticks or bar-to-bar changes (absolute and percentage).
Liquidations
Liquidations are viewable in dollar or coin terms, and in the form of long and short, total count, long only, or short only.
Users may also enable a hitmarker sound to play on each liquidation.
Funding
Funding is viewable standardized to per 1 hour, 8 hours, 24 hours, or 1 year, and in the form of rate (%), total coin spend, or total dollar spend.
Funding spends are calculated as funding rate times open interest.
The view input of this indicator controls whether the average or the last value is returned for each individual bar.
By default Velo shows funding rates as they update, rather than as they were at their last payment interval. This may sometimes be referred to elsewhere as a "predicted funding rate."
Premium
Premium is mark price vs. index price as reported by each exchange. It is viewable in terms of dollars or percent.
The view input of this indicator controls whether the average or the last value is returned for each individual bar. The moving average input controls if and how an average is returned for a period of multiple bars.
See how Binance defines mark prices and index prices here. Most exchanges follow similar definitions.
Volume
Volume is viewable in dollar or coin terms, as well as in the form of volume delta or cumulative volume delta.
The volume delta of a period is the value of market buys minus the value of market sells during that period. Cumulative volume delta is the cumulative sum of the volume deltas of multiple periods.
Tape
Tape data is viewable in total trade count or tape speed (trades per minute) terms, as well as in the form of trade delta or cumulative trade delta.
The trade delta of a period is the number market buys minus the number of market sells during that period. Cumulative trade delta is the cumulative sum of the trade deltas of multiple periods.
Moving Average
In addition to two standard moving averages, volume weighted average price (VWAP) and open interest weighted average price (OIWAP) are viewable.
The VWAP is the total dollar value of all trades in a period divided by the total number of contracts traded in a period.
The open interest weighted average price (OIWAP) is the total dollar value of all open positions in a period divided by the total coin value of all open contracts in a period.
Because of the less volatile nature of open interest, an OIWAP may at times appear similar to a standard moving average. This indicator may be reworked in the future.
Returns
Returns (bar to bar close) are viewable in absolute or percentage terms and over one or multiple periods.
Realized Vol
Realized volatility is the annualized standard deviation of percent returns over a given period.
Total Return
Total return is the estimated value of a long position held in a perpetual future after funding rate payments are considered. Payments are not assumed to be compounded into the position and this value may vary slightly from true actualized returns.
