This indicator allows to visually estimate the size of the candle body in points and to compare it with the average size of candle range within the specified period. The histogram shows the bullish candle body size (blue by default), and the bearish candle body size (red by default). The line (light blue by default) shows the average value of the candle range size within the specified period.
The indicator levels correspond to the candle sizes of 100, 300, 500, 1000 and 2000 pips for 5-digit quotes. For 4-digit quotes they are 10, 30, 50, 100 and 200 points, respectively. If the default levels are not enough, you can always add the missing ones.
The indicator has only one adjustable parameter, which is the averaging period - Average Period.
