Where?

I have stated that 4-8-21 was not mine and that I have found it from a blogger out there somewhere who is no longer blogging.

Thanks to a comment poster dukeofdan, you can read the original information at http://filteringwallstreet.blogspot.com/

Notice the author uses 21ema while I use 21sma. It might have been a brain fart on my behalf; however, it works for me. You might want to compare charts for differences.

I have given due credit to the author!
