Trend Indicator Development in Pine Script

Job ID: 38661200

Budget: €250 – €750 EUR

I'm looking for a proficient Pine Script developer who can create a trend indicator based on the Williams Percentage Rate.
I want to calculate the area between -50 and 0 and the area between -50 and -100, considering only the extended hours (aftermarket and premarket) of a single day.
I would like to see some sort of labels (ex. AreaUp, Area Down) over every single day
