Turtle Rules adapted for stockcharts scans

The entry portion was just a channel breakout - one method used 20 days, another used 55 days.

So, one scan might be

and [close x Upper Price Chan(20)]

But, it really needs a refinement, because once prices start climbing (if they do) you will get a signal every few days. So, you probably want to see a period of flatness in the upper price channel before the breakout. Like

and [5 days ago Upper Price Chan(20) = 10 days ago Upper Price Chan(2)]
and [close x Upper Price Chan(20)]

If you want to catch a new long term up trend early, you might want to test for larger time frame price channel falling, like

and [Upper Price Chan(63) < 30 days ago Upper Price Chan(63)]
and [Upper Price Chan(63) <= Upper Price Chan(251)]

That would get situations where the larger time frames are still falling. But, if the larger trend is still down, 20 day highs are often good shorts.
