Crypto price alerts

On Telegram only. The same TradeYar bot you have already started sends you a message when price reaches your number. No app to install, no email, no signup.

Because no VAPID key pair exists on this platform, and without one the browser cannot create a push subscription at all. A 'browser notification' toggle would look like it worked, deliver nothing, and raise no error. We would rather ship the channel that works and be explicit about the rest.

It is Telegram's own rule: a bot cannot send the first message to a person. Until you have pressed Start once, Telegram rejects our message. So we only accept a handle that has already started the bot.

So that nobody can create alerts in your name and fill your Telegram with them. An alert does nothing and sends nothing until the code delivered to your own chat is typed back.

From LBank's public live futures feed — the same source the live-prices page on this site reads. The server compares armed alerts against the latest price every 15 seconds, and skips the round entirely if that price is more than 20 seconds old, because firing on a stale tick is worse than not firing.

Once. When price reaches the target you get the message and the alert closes. Set it again if you want to keep watching that level. Armed alerts live for at most 30 days.
