How can the stock market be up 1% in the morning and still close lower, and what is a

candlestick chart showing you? Every trading period, whether it's one minute or one day, has four key prices: the open (the first trade), the high, the low, and the close (the last trade). Traders call these OHLC. A candlestick chart draws each period as one "candle." The thick body runs from the open to the close, and the thin lines above and below it, called wicks or shadows, reach up to the high and down to the low. If the close is above the open, the candle is usually drawn green or hollow; if it's below, it's usually red or filled. Colors are just a chart setting, so it's worth checking yours.

Monday, Nov 2, is a good example. The S&P 500 was up about 0.5% just after the 9:30 a.m. ET open and rose as much as 1.1% during the day, but it closed down 0.51% at 7,541.40. The Nasdaq Composite was up as much as 1.4% and finished down 1.07% at 25,164.32. On a daily chart, that kind of day shows up as a red candle with a long upper wick: the wick marks how high prices got, and the body shows they ended below where they started. Meanwhile the Dow rose 0.41% to 51,983.98, so the three indexes drew very different candles on the same day.

One important limit: a candle only describes what already happened inside its own time period. It doesn't tell you what the next candle will do, and on its own it doesn't even show whether the high or the low came first. You'd need a shorter timeframe, like hourly candles, to see that. Got questions about reading charts, candles or wicks? Ask below, there are no silly questions here.
