A Long White is a single candle pattern which signals strong buying pressure. Coloured white (or green) to represent bullish sentiment, the longer the candle, the further the close is above the open and the more aggressive the buyers.
Identified as a continuation pattern particularly when found in the price action of an uptrend, the Long White can also be used as reversal pattern when found in a downtrend.
When charted with high trading volume on an uptrend, the Long White candle can be used to identify a significant resistance level. When price breaks the Long White candle resistance zone, it signals the uptrend’s strength and its further continuation.
