  Good afternoon guys, i wonder if anyone can help. I am trying to colour my upper and lower Bollinger bands Green when the middle moving average is rising and Red when the middle Moving average is falling. Can someone help please? Ive copied the basic code for the Bollinger Bands themselves. Thanks for any help you can share!

  Best regards

  Bollinger Bands

  a=average [21] (close) b=STD[21](close) Bollup= BollingerUp[21](close) Bolldn=BollingerDown[21](close) Return Bollup,Bolldn,a

  1 2 3 4 5

  a=average [21] (close) b=STD[21](close) Bollup= BollingerUp[21](close) Bolldn=BollingerDown[21](close) Return Bollup,Bolldn,a

  Hi @Alfy

  To determine the direction of the average, you can use the Linear Regression Slope.

  You may be thinking, what does linear regression have to do with a moving average?

  Where the linear regression intersects with the moving average, that is the zero point of the linear regression slope…
