TradingView's Linear Regression indicator for TOS?

Does anyone have or know of a TOS script that is similar to TradingView's built-in Linear Regression script (blue/red channel in image below)?

Linear Regression channel is available as a built-in drawing tool in your ThinkorSwim. However, it will not include the blue/green zones like TradingView.

Hey @diazlaz Have you worked w "Opacity" in TOS? Just wondering if we can make those SD clouds more transparent. I've seen it work but can't find the example to borrow from. Thanks, Markos

I was able to add opacity. It helps a lot to see the chart behind it, but the opacity adjustment doesn't work for me, seems locked at 50%. Thought someone else might appreciate it.

Code:

#

input price = close;
input deviations = .8;  #set your deviation units here.
input length = 100; #set your channel lookback period here.
input opacity = 50;

def regression = InertiaAll(price, length);
def stdDeviation = stdevAll(price, length);

plot UpperLine = regression + deviations * stdDeviation;
plot MiddleLine = regression;
plot LowerLine = regression - deviations * stdDeviation;

AddCloud(MiddleLine,  UpperLine,  Color.GREEN,  Color.GREEN, opacity);
AddCloud(MiddleLine,  LowerLine,  Color.RED,  Color.RED, opacity);

UpperLine.SetDefaultColor(Color.GREEN);
MiddleLine.SetDefaultColor(GetColor(8));
LowerLine.SetDefaultColor(Color.RED);

@diazlaz @Ficus I wanted to have an LRC that was opaque. This was done w help from TOS Support.

Color Opacity can be changed to what ever one wishes via the UI under Global Colors>More...>HSV color panel.

Code:
# LRC no Lines Global Color Adj
# With help from coder in TOS chat support 9-18-2020
# Originally: tradingview like Linear Channel w/ fills
# @JonPM Community Request in useThinkscript
# VERSION
# 2020.09.08 V1.0 @diazlaz - Linear Regression Channel with Cloud and variable
#                            timeframe.
# 2020.09.18 V1.1 @markos - Color Opacity can now be changed via Globals in UI.

input price = close;
input deviations = 1.0;  #set your deviation units here.
input length = 80; #set your channel lookback period here.

def regression = InertiaAll(price, length);
def stdDeviation = StDevAll(price, length);
def UpCloud = regression + deviations * stdDeviation;
def DnCloud = regression - deviations * stdDeviation;
def MiddleLine = regression;

DefineGlobalColor("Bullish", Color.light_green);
DefineGlobalColor("Bearish", Color.light_RED);

AddCloud(middleline,  upcloud,  GlobalColor("Bullish"),  GlobalColor("Bullish"));
AddCloud(middleline,  dncloud,  GlobalColor("Bearish"),  GlobalColor("Bearish"));

# End LRC wo Lines

How do you guys trade using this?
You don't really trade based on this alone. The green and red zones give you an idea of possible support and resistance as well as the overall trend direction. Just notice how the price seems to bump up and down near the top, bottom and middle.

how do you code to count the number of times the middle line cuts through the body of the candle? Say input length is 80, so i want to see among the 80 candles, how many of the candle bodies got cut through by the middle line.
