Reading prices: open, high, low, close and candlesticks

The contest on this site fills orders using these 4 daily prices. Once you understand them, you'll know what price your order will get.

1The 4 prices of each day (OHLC)

Open = the first price of the day · High = the highest · Low = the lowest · Close = the last price of the day.

The close is the price people talk about most. "NVDA closed up 2% today" means today's close compared with yesterday's close.

2Candlesticks

A candlestick chart draws all 4 prices in a single bar. The thick body spans the open to the close, and the thin wicks above and below show the high and the low. A green (or blue) candle = it closed higher than it opened. A red candle = it closed lower than it opened.

3Price gaps

Some days the price opens far away from yesterday's close, for example after an earnings report. This is called a gap. If the price opens past your stop-loss, the stop can fill at a worse price than the one you set.
