This script allows you to set a variable number of linear regressions with alternating colors you can select. It will have a partner oscillator script shortly so you can see how the different trends change and interact with each other over time.
The script is currently very slow if you set the period for the linear regression too high. I recommend not going past 100. Works very well on the high time frames for this reason.
Anyone that knows of a faster way to run these calculations please let me know!
