Candlestick
A candlestick shows four prices for one period: the open, the high, the low and the close.
The body runs between the open and the close. The thin lines above and below, called wicks, reach the high and the low.
A candle says where price went inside that period. It does not say in what order it got there.
Also called: candle, OHLC
