Good morning all! Thanks for including me in this group.

Here is one of my favorite studies. It uses the Least Squares Method. I would love your thoughts.

There is nothing out there that can catch the turns as well as this baby can!

Code:

i love those additions as well. feel free to ask me about any of the stuff in the code. If anyone is interested, there is a way to extend those regression channels into the future as well.

has anyone used this indicator at all in the past or currently?

Double LS lower study I did a while back. Different lengths to look for color agreement.

LR and Least Square methods work best for inter and longer time frames, my experience and in discussions with other CMTs, they were never designed for short term/intraday trading. This indicator will work for longer holdings and timeframes.

if anyone has experience using this successfully for short term time frames or have a pairing that works let us know.

Hguru Just 2 LS studis with different length inputs. The idea saw both turning red or green was a safer signal. Sometimes th short length will change color while the longer length does not. So then you could look at whether that was a false or true change. If the short then bounces good chance it is not a change in direction.

It is a linear regression slope using least squares method. It is curve fitting as far as I understand. Can an explaination be given why it is not suitable for any time frame. Just curious , I do not use it.

What are the differences between the yellow and the purple arrows? I also see the magneta arrows label going green and red, and the short and long % changing. I really like this indicator and i'd like to test it out. Any assistance will be greatly appreciated. thanks

i love those additions as well. feel free to ask me about any of the stuff in the code. If anyone is interested, there is a way to extend those regression channels into the future as well.

has anyone used this indicator at all in the past or currently?
