Open in the editor ↗ · The link creates the template in the editor without an account. Signed in, you find it under “My chains” → “Choose template”.
The Donchian Channel underlies many trend-following systems: a close above the highest high of the last 20 candles counts as a breakout, one below the lowest low as a break down. Enter your system’s https address in both webhook nodes; without it the chain cannot be activated.
