Regression Ray for Metatrader 4

I would like to share a script with you guys.
Just some fun with linear regression below.

Here's a version which draw a regression line from bar 0 to bar 199. Its just a one time visual indicator of market bias. Then you can guess , or estimate once you get practice , which direction the market will go in , i guess!

After playing around with it , I feel that using two linear regression lines (20 and 200 bars) is better as a visual aid. Its the best linear regression can do as a visual aid.

It usually forms an x on the visible chart , maybe that's why there's an x in forex?
