Crypto scanner: one alert for many coins

Instead of building a chain for every coin, run one chain as a scanner across many coins. Bellchain computes each coin on its own and tells you which one fires, say RSI below 25 or more than 4% within an hour.

How it works

How the scanner works

In the candle you choose Several coins: your own list or the top N by volume, renewed every day. Each coin has its own RSI, its own cooldown and its own alerts.

If several coins fire at the same candle, Bellchain bundles them into one message, one line per coin with its values. The replay shows beforehand how often each coin would have fired.

  • Your own list or top N by turnover, renewed every day.
  • From Pro for 10 coins, with Trader for 50, with Community for 100.
  • A scanner counts as one active chain.

FAQ

Questions and answers

How many coins can a scanner watch?

A list holds up to 100 coins. How many run at the same time depends on the plan: Pro 10, Trader 50, Community 100, across all active scanners together. You can test any list in the replay, Free included.

What does top N by volume mean?

Instead of a fixed list, the scanner takes the N coins with the highest turnover of the last 24 hours against a quote currency such as USDT. The list is renewed every day; stablecoins, leveraged tokens and tokenized stocks are left out.

Won’t I get lots of messages?

Each coin has its own cooldown, and when several fire at the same candle, one message lists them all. The replay shows beforehand how often that would be, for each coin on its own.

Does a scanner count as several chains?

No, a scanner counts as one active chain. Its coins count towards the plan’s coin limit as well.
