Overview
Dragonfly Doji - Bullish treats a candle as a doji when the range is positive and the body is no larger than five percent of the range, then requires the upper shadow to be no larger than the body. On a match it draws a DD label below the low, using an ATR offset, tints the bar background blue, and fires an alert. The only user setting changes the bullish label color; body and shadow thresholds are fixed in the code. It does not place trades or set exits.
- Dragonfly doji body and shadow test
- DD label below the candle
- Alert when the pattern appears
- Blue background highlight
- Adjustable bullish label color
