Deviation Trend Profile [BigBeluga] For Thinkorswim

[chewie76]

This is an adaptation of the Deviation Trend Profile converted from Tradingview to Thinkorswim.
Original Link: https://www.tradingview.com/script/6Wr1CEuo-Deviation-Trend-Profile-BigBeluga/

A statistical trend analysis tool that combines moving average dynamics with standard deviation zones and trend-specific price distribution.

• Standard Deviation Zones: Calculates ±1, ±2, ±3 and ±4 levels from the SMA using ATR, forming dynamic envelopes around the mean.

The shaded areas are the 3-4 standard deviation from a moving average (default 50 SMA). Notice in the below picture of /GC on the four-hour timeframe, price was rejected every single time when it hit the ±4 levels.

Color Candles can be turned on/off in settings and align with the Standard Deviation Zones.
