About
All-in-one candlestick pattern panel: marks every classic reversal and continuation pattern in a single overlay — engulfings, haramis, doji, hammer family, stars, soldiers/crows, piercing/dark cloud, tweezers, marubozu, belt hold, abandoned baby.
- Each pattern has its own marker, text label and colour so you can scan for confluence.
- Best used as a scanner to find setup candidates; combine with your own confirmation rules.
