Frequently asked questions

What does "8 days out of 10" mean?

Over the long run the closing price lands inside the published range about 80% of the time. On the other 20% of days it falls outside — and that's visible in the record.

Why don't you say whether the price will go up or down?

We tested it on years of data: direction is no better than a coin flip. How far the price moves, however, is predictable — so that's what we publish.

If this works, why don't you trade it yourselves?

A range doesn't tell you where the price goes, so it isn't a profit signal by itself. It's a risk tool for stop-losses, leverage, grid bots and liquidity ranges — it helps people who already trade.

How does the free trial work?

After the launch period, logging in with Telegram unlocks 7 days of full access — once per account. The bot reminds you a day before it ends, and the history stays open without a subscription.

Is this investment advice?

No. We publish a statistical review of volatility and never recommend buying or selling.
