This thread is fun, it's like game The Werewolves of Millers Hollow, guess between serious traders and cheater who want to sell something. :)
The best filtering method I've found, is at any time, look at the page number of the recent post, let's call it X, then substruct x-300, let's call the new number Y.
Now, go to page number Y.
You don't have to scroll back manually, you can change the address of this page, where it says &p=X, simply change the X to your new page number Y and click Enter. Don't change any of the other fields.
Start clicking on account links from this page backward. You may do so by middle-clicking on all links on a page then take a look at the tabs which were opened, then go to the previous page and so on.
If you find an account which is not private, not closed, which belongs to a user who still exists, and the account is not wiped out, you have probably landed on a profitable account and you may want to follow it or copy its signals.
I warn you though - such a finding is very very hard. Probably a tedious task but should worth you more than any other algorithm for finding good accounts here.
:) thanks, anyway. Actually I can do it automatically in less than 10 mins like you said, query all systems in this thread to check, etc.
Although I believe that copying something you don't understand is extremely risk and not necessary to stay profitable :), but was working as a quant researcher in quant fund, I think those threads maybe a sources for hedge fund to find the good candidates using your methods.
