Questions

Is it free?

Yes. Every feature is free while BehindCandle is in beta. After launch the Free plan stays free, and paid plans unlock the advanced order flow tools.

Do I need an account or an API key?

No. Open the chart and start. You do not connect any exchange account and no API key is needed.

Where does the market data come from?

Live prices, order books, trades and open interest load in your browser directly from public market data feeds of major crypto exchanges. BehindCandle does not store or resend that data.

Does it give buy or sell signals?

No. BehindCandle shows market data and analytics such as walls, fills, liquidity and open interest. What you do with it is your decision. Nothing on the site is investment advice.

Which symbols can I chart?

Bitcoin, Ethereum, Solana and the other USDT perpetual futures, plus gold, silver and crude oil contracts. Search by name, for example GOLD or USOIL.

Can I build my own indicators?

Yes, soon. Custom indicators are coming to the Pro plan after accounts launch. You will write them in a few simple lines, save them to your account and add them to any chart.

How do alerts work?

Draw a horizontal line, ray or trend line. When the price crosses it you hear a sound and get a browser notification. Alerts run while the chart tab is open.

Open the chart and watch the walls.
