Candlesticks, What is it?

Japanese candlesticks are a way of displaying price that packs four pieces of data per session into one candle: the open, close, high and low. The candle "body" spans open to close, and the "wicks" mark the high and low. A green (or white) candle means the close was above the open (an up day); red is the opposite. Traders read candle shapes and sequences to anticipate a reversal or continuation, such as a "hammer" candle or an "engulfing" pattern. Candles alone are not enough; they are read with levels and volume. FoudaLens shows an interactive candlestick chart for every stock.
