FollowLine: Bollinger Band Trend Detection with an ATR Filter

Summary

FollowLine is a chart indicator intended to identify market trends using Bollinger Bands. Its settings let a user choose how many bars to display and set the band period and deviation, which control the indicator’s lookback and band width.

The indicator can optionally apply an Average True Range filter, display alerts, and mark trend changes with arrows. The description provides no formula for how these components combine, nor any backtest or performance evidence. It therefore explains the available controls and intended use for manual trading, but does not establish that its signals are reliable across markets or timeframes.

Key ideas

• The indicator uses Bollinger Bands to identify potential market trends.
• Users can configure the number of displayed bars, band period, and band deviation.
• An optional ATR filter can be enabled.
• Alerts and arrows can mark signals and trend changes.
• The description gives no testing evidence or detailed signal formula.
