Live rates across crypto exchanges
The site's sections in the chat, and route tracking on your own thresholds: the bot reports in numbers that a condition is met. It places no orders and asks for no API keys. Access is opened by the bot's owner.
Open the botYes. All tools are available without registration or payment.
No. We only use public market data and never ask for keys or passwords.
Spot tables refresh every 3–5 seconds, funding rates every 10 seconds, P2P every 30 seconds, bank rates several times per hour. The venues themselves deliver prices at least every 30 seconds.
