Description
Bollinger Lows wraps price in a Bollinger Band envelope and watches the lower band for exhaustion. When price stretches to the lower band and turns, it prints a Buy arrow and flips a colour-coded trend line — green in uptrends, red in downtrends, Supertrend-style. Internally it blends the lower-band cross with a cumulative volume-spread “shadow” stream and an EMA/ATR envelope to filter noise, and fires popup/sound/push/email alerts on each new arrow (with intra-bar de-duplication so you are not spammed). Works on any symbol and timeframe; MA period, band multiplier, ATR settings and the trend-flip factor are all adjustable. Free MT5 (.mq5) source included. Educational tool, not financial advice.
