Blackhole — screener, alerts and exchange data

JustScreener sweeps Blackhole trading pairs every minute: price, open interest, turnover and funding across futures contracts. When a change exceeds your threshold, the screener sends a browser (push) or Telegram notification — so you react to the move instead of scrolling charts.

The price screener catches sharp pumps and dumps, the OI screener — new money entering positions, the 24h turnover screener — 24h-turnover spikes, the funding screener — overheated longs and shorts, and the custom screener combines several conditions into one scenario. Thresholds, intervals and the pair list are configured in the dashboard; you can watch Blackhole alone or all 5,400+ coins across 10 exchanges at once.
