ZenAlgo - Doji (free)
Doji looks for indecision candles that appear with unusual volume and a change in short-term delta direction. This extra context filters out many ordinary doji candles and focuses attention on moments where participation and pressure are changing together.
How to read it
A doji has a small body relative to its full range. On its own, that only says buyers and sellers finished close to where they started. ZenAlgo Doji waits for more: optionally a PVSRA volume spike and a delta sign flip.
A label below the candle is a bullish result; a label above it is bearish. The signal can refer to the current or immediately preceding doji candle. Hover over the marker to see the doji type, direction, and PVSRA volume multiple.
Labels and values

| Dragonfly Doji | Long lower wick and very small upper wick |
| Gravestone Doji | Long upper wick and very small lower wick |

| BULL / BEAR | Direction of the delta flip |
| PVSRA xN (length) | Current volume divided by average volume over the shown lookback |
The REVERSAL, CLASSIC, and LOOSE presets change how strict the candle geometry and volume requirement are. CUSTOM exposes those thresholds directly.
The marker describes a qualified moment of indecision. It does not guarantee that price will reverse in the marker's direction.
