High-Low Difference

This script will display the high-low difference both as a histogram and as a label on the chart.

Explanation:
highLowDiff = high - low: This calculates the difference between the high and low prices for each candle.

plot(...): This will plot the high-low difference as a blue histogram on the chart.

label.new(...): This will create a label at the top of each candle with the value of the high-low difference. You can adjust the position of the label and its appearance as needed.

Customization:
You can change the color, line width, or style of the plot and the labels to suit your preferences.
If you'd prefer the label to appear at a different location, you can modify the parameters inside label.new(), such as adjusting the position or the size of the text.
