How fast are the alerts?
How fast are you compared to competitors?
It depends on the exchange. For CEX with servers in Tokyo (Binance, Bybit, OKX…), our detection-to-dispatch latency is sub-1 millisecond. Our infrastructure sits in the same AWS Tokyo region, so the round-trip is virtually zero.
For Korean exchanges like Bithumb and Upbit, expect around ~20 ms. Their announcement servers are in Seoul, so there's an incompressible Seoul ↔ Tokyo network hop. That said, the major CEX you'd actually buy on (Binance, Bybit) are in Tokyo — so the full pipeline from alert to order execution stays sub-millisecond if your trading bot is co-located with us.
Most competitors rely on polling or Telegram relays that add hundreds of milliseconds to seconds of delay. We are consistently the lowest-latency option available today across all monitored exchanges.
Where are your servers located?
Our entire infrastructure runs on AWS Tokyo (ap-northeast-1). This is where the majority of major CEX (Binance, Bybit, OKX) have their matching engines and announcement servers.
For the absolute best performance, we recommend running your trading bot on a server in AWS Tokyo as well. With both ends in the same datacenter region, you can expect sub-2 ms end-to-end latency between our WebSocket dispatch and your bot receiving the message — leaving you the maximum edge to execute trades before the market moves.
