Detailed Explanation :-
Real Bodies
Each candlestick is composed of a real body and two wicks (which are also called shadows or tails). The real body is the substantial part of the candle. It reflects the difference between the open and close price for that period.
The open and close prices are the first and last transaction prices for that time period. When there is no real body or the real body is very small, it means the open and close prices were the same or almost the same.
The real bodies are typically one solid color, though they may also be hollow, with only their edges displaying a color. Their coloring depends in part on the color scheme used by your charting platform, but white/black and green/red are commonly utilized.
A white or green candle means the price finished higher over that time period. Because the closing price is higher than the open price, the bottom of the real body represents the open price and the top of the real body represents the close price.
A black or red candle means the price finished lower over that time period. Therefore, the top of the real body is the open price and the bottom of the real body is the close price for that time period.​
Wicks or Shadows
The wicks or shadows—the thin lines above and below the real body—represent the movements above and below the open and close prices.
The highest part of the wick on top of the real body marks the high price for that period. If there is no upper wick, then the top of the real body was also the highest price during that period.
The lowest part of the wick on the bottom of the real body marks the low price for that period. If there is no lower wick, then the bottom of the real body was also the lowest price during that period.
The difference between the high and low prices is the price range for the period.
