This ProBuilder code snippet is designed to visually highlight candlesticks on a chart where the body is less than or equal to half the size of the shadows. This can be useful for traders looking to identify specific candlestick patterns that might indicate indecision or potential reversals in the market.

DEFPARAM CalculateOnLastBars = 1000
R=0
G=255
B=0
F=255

IF close > open THEN
    UpperShadow = high - close
    LowerShadow = open - low
ELSE
    UpperShadow = high - open
    LowerShadow = close - low
ENDIF

Shadows = UpperShadow + LowerShadow
Body = range - Shadows

IF Body <= (Shadows / 2) THEN
    DotVal = low - (100 * pipsize)
    DRAWTEXT("•",barindex,DotVal,Dialog,Bold,12) coloured(R,G,B,F)
ENDIF

RETURN

Explanation of the Code:

• DEFPARAM CalculateOnLastBars = 1000: This line sets the indicator to calculate based on the last 1000 bars on the chart.
• Color Variables (R, G, B, F): These lines define the color and opacity for the drawing. Here, it sets the color to green with full opacity.
• Conditional Shadows Calculation: Depending on whether the close is greater than the open (bullish candle) or not (bearish candle), it calculates the lengths of the upper and lower shadows.
• Shadows and Body Calculation: It sums the upper and lower shadows to get the total shadow length and subtracts this from the total range (high to low) of the candle to get the body length.
• Conditional Drawing: If the body is less than or equal to half the length of the shadows, it draws a dot below the low of the candlestick. The position is adjusted by 100 times the pip size to ensure visibility.
• DRAWTEXT Function: This function is used to place the dot on the chart, with parameters specifying the text style and color.

This snippet is particularly useful for identifying candles where the price action is uncertain or balanced between buyers and sellers, often seen in doji or spinning top formations.
