Open price?

This shows the first price traded during the formation of the new candle. If the price begins to trend upwards the candle will turn green/blue (colors vary depending on chart settings). If the price declines the candle will turn red.

High price

The highest point of the upper wick shows the highest price traded during the time. If there is no upper wick or shadow, it means that the open or close price was the highest traded.

Low price

This can be the price at the bottom of the lower wick. But if there is no lower wick then the lowest price traded is the same as the open or close price in a bullish candle.

Close price

The close price is the final price that investors trade during the time of the candle formation. If the close price is lower than the open price, the candlestick will become red. If the close price is higher than the open price, the candlestick will be green or blue. This also depends on the chart settings.

The wick

The wick is also known as a shadow. These points are significant because they indicate the extremes in the price for a particular charting time. It is easy for traders to identify the wicks because they are visually thinner than the body of the candle. This is where the strength of candles becomes apparent. Candles can help investors keep an eye on the momentum of the market and away from the static of price extremes.

Direction

The color of the candle shows the direction of the price. If the price of the candlestick is closing higher than the opening price of the candlestick, the price is going upwards and the candle will be green or blue. A red candle will mean that the price closed lower than the open.

Range

The range is the difference between the highest and lowest price of a candle. Traders can calculate this by taking the price at the top of the upper wick and subtracting it from the price at the bottom of the lower wick.

Knowing this about a candle, and what the points show, means investors using candlestick charts have a clear advantage when it comes to distinguishing trend lines and price charts.
