Features
Your chart first, the data underneath.
Draw, add indicators and read price on crypto charts — and on stocks, forex and CME futures from the Trader plan. Order-flow panels open below the same chart, so levels and flow are read together.
Crypto charts
Order flow across five exchanges.
Agg. CVD, open interest, funding, net long/short and liquidations add up a coin on Binance, Bybit, OKX, Coinbase and Hyperliquid, each counting the exchanges that publish its data. The panel header shows how many exchanges are counted, and you can switch any of them off. Pro and Elite.
Order flow across five exchanges.
Scripts that read the flow.
Write indicators and strategies in AlertaScript and test them on past data, on every plan. With Pro, a script reads funding, open interest, CVD, net longs and shorts and liquidations as series.
AlertaScript
Alerts set from the chart.
Set alerts from the chart or a watchlist. On paid plans, price alerts are also watched when the app is closed, on Binance, Bybit, OKX, Coinbase and Hyperliquid, stocks, forex and CME futures. Pro adds technical, trendline, watchlist and funding-rate alerts, and script alerts that run around the clock on those five crypto exchanges.
