ThinkScript Pivot Points Mimicking Active Trader Pro

I'm looking for someone to mimic Active Trader Pro pivot points in Thinkorswim. ATP has pivot points that are constantly moving intraday due to the calculation. The calculation is based on the daily candle for the current day on the intraday chart, hence why it's always on the move.

The calculation is: PP = Hi + Lo + Last Traded / 3
The support and resistance levels are the typical calculations.
