Follow Line Indicator for MT5

In short: Follow Line for MetaTrader 5 is a non-repainting trend-following line built from Bollinger Bands and an ATR filter. It moves with volatility, shows uptrend and downtrend zones, and plots buy and sell signals with a built-in back-test panel.

How the line behaves

Follow Line tracks the market with Bollinger Bands and, optionally, an ATR filter. The result is a line that follows price at a distance set by volatility:

• Green line below the candles: bullish trend. Buy arrows appear when the trend flips upward.
• Red line above the candles: bearish trend. Sell arrows appear when the trend flips downward.

Because the line is anchored to volatility, it widens in active markets and tightens in quiet ones, so it works both as a trend indicator and as a dynamic stop reference.

No repainting

Signals are calculated in real time and do not repaint, so what you see on the chart in history is what you would have seen live. That matters for anyone who evaluates an indicator by scrolling back through charts.

Tuning the settings

• BB Period: higher values give a smoother, more stable trend; lower values respond faster to short-term changes.
• BB Deviations: higher values reduce false signals but give fewer entries; lower values give more entries.
• Use ATR Filter: on, it smooths volatility and avoids sudden flips; off, the line reacts directly to the Bollinger signals.
• ATR Period: lower values make the filter more reactive; higher values stabilize the line for clearer long-term trends.

As a rule, scalpers lean toward lower periods and day or swing traders toward higher ones, but check what works on your own symbol.

Test it on the chart

In the Tester group, turn on Use Tester, pick a Test Start Time, and set TP Points and SL Points. The panel reports total trades, wins and win rate directly on the chart, so you can compare settings quickly.

Alerts

Use Alerts shows pop-up alerts for buy and sell signals, and Use Push Notifications sends them to your MetaTrader 5 mobile app.

How to trade with it

1. Trade in the direction of the line color and use flips as entry or exit triggers.
2. Place stops behind the line, which already reflects current volatility.
3. Be selective in sideways markets, where trend-following lines flip more often.
4. Check a higher timeframe for the overall direction.

Compare it with other trend-following lines: the Trend Magic indicator and the HalfTrend indicator.

Frequently asked questions

Does Follow Line repaint?

No. It is a non-repainting indicator, and all signals are calculated in real time.

How are trends shown?

When the trend turns bullish, a green line appears below the candles; when it turns bearish, a red line appears above them. Buy arrows appear when the trend flips upward and sell arrows when it flips downward.

What do BB Period and BB Deviations do?

BB Period sets the Bollinger Bands period: higher values make the trend smoother and more stable, lower values react faster. BB Deviations sets the band distance: higher values reduce false signals, lower values give more frequent entries.

What does the ATR filter do?

When enabled, it smooths volatility and avoids sudden trend flips. Turning it off makes the line react directly to the Bollinger signals. ATR Period sets how sensitive the filter is.

Which markets can I use it on?

Forex, crypto and indices, for scalping, day trading and swing trading.

Does it have alerts and a tester?

Yes. Pop-up alerts and push notifications to MetaTrader mobile, plus a tester group with start date, TP points and SL points that reports total trades, wins and win rate on the chart.
