I was watching a Youtube video today about the 200 MA, and he refers to the MA 200 as 200 "week" MA not 200 day MA. When I add the SMA to my chart and change the "length" field to 200 I get a totally different outcome to what he has on the video.

I believe that it would be better if you asked the question to the person who presented that analysis. I won't say that it's bad or good (I didn't even listen to it in detail), but it seems that he didn't explain it well, because you have to search further in order to understand it.
