What is the One Black Crow Candlestick Pattern?
In forex trading, the One Black Crow pattern can be used as a strategy to identify potential selling opportunities. It is generally thought that the pattern is more reliable when it appears after a long uptrend, as it suggests that the bulls have lost their momentum and the bears are starting to take control.
The One Black Crow pattern is characterized by a large black candle with a small body and a long wick on top. The small body indicates that there was little price movement during the period, while the long wick suggests that the bears were able to push the price down significantly before the bulls were able to push it back up.
