to redo the prices.last i just typed them and copied them into each individual box in the GUI... and then made sure they were all correct so that it would work. I COULD use NOTEPAD++ to edit them though but i just chose to use the GUI instead so that everything was done correctly.
Here are the commands that I have used:
trade.py update nima/rush -F -A
trade.py update nima/rash -F -A
trade.py update nima/bur -F -A
trade.py update branglal/skri -F -A
trade.py update branglal/gib -F -A
Odd, I didn't think the GUI would let you enter a number with a comma in it -- do you know how you managed to enter that value? (I'd like to make it so that it either translates it for you or at least warns you)
