Slope of a Linear Regression Trendline

So, I am looking at longer-term charts (3-Year, Weekly) of scan results and have added the default Linear Regression Trendline to the chart. I can see that this line can have a positive or negative slope depending on the chart. Here’s my question: Is there a known script that would allow me to remove stocks with negative slopes in this time frame? Thank you in advance for your help.

Be sure the aggregation is set to Week (Wk).

Currently, it looks like there are a few more than 3500 symbols that the scan returns.

mashume, Thank you. It works great! I used 156 for the length as I think there are about 156 weeks in 3 years. I did notice, however, that if there are fewer than this number of bars, the stock will be rejected by the scan even if the linear regression slope is positive. Are you aware of any way to modify the script so that stocks with less than 156 bars that have a positive slope will be listed?
