How It Trades
- Compute the 20-bar CCI from each bar's typical price (the average of its high, low and close) measuring how far the bar sits from its recent average in units of normal deviation.
- Buy when CCI crosses above +100. In Lambert's original design this is not an overbought warning but the opposite: the point where a move is finally strong enough to be called a trend.
- Sell when CCI breaks below −100, marking a move of the same conviction in the other direction.

//@version=6
// CCI Trend — sort.finance. Fills at the signal bar's close, 0.02% fee a side,
// whole account per trade, as the backtest. History and indicator warm-up
// differ from the site's, so expect close to the same trades, not identical.
