Read this
An alert is a number crossing a line you chose. It is not a signal from us and not a recommendation. The data comes from Deribit's public API every 15 minutes, so a spike that reverses inside 15 minutes can be missed. Percentile and 24h rules need history: right after launch they stay silent until we have stored enough points (about 12 hours for 24h change, 30 days for a full percentile window).
FAQ
Which data source is used?
Deribit public API: the BTC and ETH perpetual tickers for price, funding and open interest, the DVOL index, and the options book summary for 25-delta skew (put IV minus call IV around ±7% out of the money on the expiry 5 to 10 days out).
How often is it checked?
Every 15 minutes. One message per alert at most every 4 hours, and only when the rule turns from false to true.
How do I pay?
In the bot, in USDT or USDC on TRON, Ethereum, Arbitrum or BSC. You prepay a term; nothing renews by itself.
What happens after the free trial?
Your 3 alerts pause after 7 days. Pick a plan in the bot and they start again.
Will this make me money?
No promise. It tells you when a number you care about moves. What you do with that is your decision.
