Market Discussions

I'm quite puzzled at this after my first month of play. I've been training about 50% of my skill points into Trade thus far and it's worked out immensely for me as I've learned quite a lot of niches through EvE-Central to ascertain good buy/sell order areas. One thing that has puzzled me thus far though is why when I enter a Buy Order does the furthest option I'm offered is the 40 jumps?

I'm not looking for a rant about how Regional Buy Orders are a mistake and so on and so forth, you just don't know how to properly abuse it if your actually running station to station to gather your orders. What I want answered that I can't find after an hour of googling and forum searching is why I can't put my Buy Order range to Region. I see other players with Region orders but I'm capped at 40.

http://oldforums.eveonline.com/?a=topic&threadID=1258843 Source for example with explanation that doesn't coincide with what I'm seeing.

I've trained Daytrading to 4 Trade to 4 for example, is one of them supposed to be at 5 for this to be available to me?

TL:DR Buy Order Range is capped at 40 for me, how do I get it to Region?

Always curious to see people with 40 systems range orders.
