Key Takeaways Candlestick charts reveal real-time market behavior, not yesterday’s headlines or predictions.

Every candle compresses open, close, high, low and direction into one visual signal.

The water streaming over Niagara Falls every second is nothing compared to the stock market, which is awash in more information every moment than a person could digest in a lifetime.

The next two pieces of information are the skinny wicks that many (but not all) candles have; those indicate the high and low for that interval. The fifth bit of information is the color of the candle. If it’s red, that means the price opened at the top of the fat portion of the candle and closed at the bottom of it.
