Welcome to the Board!

There you go:

A1. The dates are displayed US-style (MM/DD/YYYY). So 10/5/2011 stands for October 5, 2011.

A2. The GDX robot is not in a long trade since August 10. The sentence "The GDX MF has been in BUY mode since 8/10/2011" refers to the GDX money flow as calculated by Pascal, not the GDX robot. The GDX money flow is an essential part of the robot but not a trading system by itself.
Currently, the GDX robot is in cash and doesn't detect any reason to change its stance ("The GDX robot is in neutral mode”; “No advised new position"). A new buy/short position would be signaled by the sentences: “The robot is currently looking for a long/short position” and “The robot will buy/short at the open. The stop level is x.xx % lower/higher than the entry price”.
