I have viewed the videos and while they are really good they have not answered my question.

In the new 12.4 one can now plot as indicators most of the fundamentals. So I have plotted the dividend yield as an indicator. I , then, created at 8% line (8/100 * 100) scaled with the dividend yield.

I'm trying to test for stock where the dividend yield stays above 8% for 250 bars

Now I want to create a scan condition that test for the dividend yield being above the 8% line for the last 250 bars.

Is this possible? I did this in stockfinder but had to write my own code.

I suspect the best way to do this would be to add Donchian Channels to the Dividend Yield indicator on the chart.

You would want to set the Period of the Donchian Channels to 250 an the Offset to 0. The rest of the settings shouldn't matter.

Then click on the Donchian Channels and select Create Scan Condition to create a condition for Chan Bottom - Greater Than 8.
