In the above figure, the pink box closes two candlesticks with long bodies compared to the candles in the blue box. A larger body indicates momentum and more movement compared to a smaller body which indicates consolidation and little movement. This applies to both rising candle and falling candles. If we are already in a long position, we would want the candles to form large bodies and move up with momentum. If subsequent candlesticks have small bodies, this might indicate that the market is coming to a standstill and it might be advisable to exit your position or you can decide to wait for further movement. Another usage is when a candlestick pierces a support or resistance line, a pierce by a candlestick with a longer body is more decisive than a pierce by a candlestick with a smaller body.
