weekly doji, topping and bottoming tails

[Jones]

I am trying to design a scan/scans that look for doji, topping and bottoming tails on weekly time frame. any suggestion is greatly appreciated.

Probably the best way to work it on a weekly time frame is using our position in range filters http://www.trade-ideas.com/Help.html#WSF_MinR5D

according to the description of Position in 5 Day Range, it is somewhat confusing as it says:
      (These filters compare the current price to the prices of the previous 5, 10, or 20 trading days)
      (because they do not look at today’s data when they calculate the range)
      (These filters update before, during, and after market hours)
so does it use the current price or not? and if not, then what about after market closes and weekend. I hope I made it clear enough. however, I came up with this scan for weekly topping tails:

would you do it any different way or modify it?

thanks
