Here is my Linear Regression 2 colors code - How can I anticipate the color switch?

Hello Everyone,

I'm using the following code for the Linear Regression but it change its color a bar late for...

Code

inputs:
  Price( Close),
  Length( 89),
  Displace( 0),
  UpColor( green),
  DnColor (red),
  PaintInBarLRCLine ("Yes");

variables:
   LinReg( 0 ),Trend (0),Transition (0) ;

if Displace >= 0 or CurrentBar > AbsValue( Displace ) then  
  begin
    LinReg = LinearRegValue( Price, Length, 0 ) ; 
  If LinReg > LinReg [1] then
    Begin
      If Trend = -1 then Transition = 1;
     If PaintInBarLRCLine = "Yes" then Plot1[Displace]( LinReg, "LinReg", UpColor );
      Trend = 1;
    End
  Else
    Begin
      If Trend = 1 then Transition = 1;
      If PaintInBarLRCLine = "Yes" then Plot1 [Displace] ( LinReg, "LinReg",DnColor ) ;
      Trend = -1;
    End;
  End;

Let me explane with an example over the FDAX...
Let's suppose we have an uptrend linear regression (LR) line yellow and then it is approching to switch direction and we came to the point where LR[4] is 12349,70, LR[3] is 12350,80 , LR[2] is 12350,68 and then LR[1] is 12350,49.

Ok so this is the situation that I actually see on my chart:

I have the UpColor between LR4 and LR3, // correct because LR4 12349,70 < LR3 12350,80
I have the UpColor between LR3 and LR2, // wrong because LR3 12350,80 > LR2 12350,68
I have the DownColor between LR2 and LR1, //correct because LR2 12350,68 > LR1 12350,49

So basically the indicator is switching color a bar late and I honestly can't find a way to change it!
... Also I would like to see the last piece of line to change color (if the condition are met) on every tick untill the bar end and its value is definitive so I know that I'm approching the switch...
How can I achive that?

HERE you have a grafic example of what I mean

Any help would be appreciated.

Thanks

UPDATE: SOLVED by adding 2 rows to the code.

This is the final version for anyone who needs them:

Code

inputs:
  Price( Close),
  Length( 20),
  Displace( 0),
  UpColor( green),
  DnColor (red),
  PaintInBarLRCLine ("Yes");

variables:
   LinReg( 0 ),Trend (0),Transition (0) ;

if Displace >= 0 or CurrentBar > AbsValue( Displace ) then  
  begin
    LinReg = LinearRegValue( Price, Length, 0 ) ; 
  If LinReg > LinReg [1] then
    Begin
      If Trend = -1 then Transition = 1;
     If PaintInBarLRCLine = "Yes" then Plot1[Displace]( LinReg, "LinReg", UpColor );
     SetPlotColor[Displace+1]( 1, UpColor );
      Trend = 1;
    End
  Else
    Begin
      If Trend = 1 then Transition = 1;
      If PaintInBarLRCLine = "Yes" then Plot1 [Displace] ( LinReg, "LinReg",DnColor ) ;
      SetPlotColor[Displace+1]( 1, DnColor );
      Trend = -1;
    End;
  End;

Will this Linrig work on NT8? Thanks.
