🔹 Bollinger Trend Lines – MT4 & MT5
Bollinger Trend Lines is a professional volatility-based trend indicator designed to clearly identify trend direction and dynamic stop levels using Bollinger Bands.
Fuses on one core principle:
follow the trend, ignore noise, and let volatility define the stop.
🔍 How it works
The indicator builds trailing trend lines using Bollinger Bands:
-
In an uptrend, the lower band trails price and can only rise
-
In a downtrend, the upper band trails price and can only fall
-
When the trend changes, the trailing logic automatically resets
An optional Safe Zone (extra deviation) allows you to widen or tighten the trailing distance without changing the Bollinger period.
✅ Key Features

📊 Signal Logic
The indicator provides a numeric signal buffer that can be used in Expert Advisors or scanners:
-
+1 → Uptrend
-
−1 → Downtrend
-
0 → Neutral / transition
Only one trend line is visible at a time, making trend direction immediately clear.
