You could be right there. The economic environment aren't the best for Iron ore start-ups at the moment. My thinking was that's its just low volume (relative to shares on issue) and big trades that go through at certain times that push it down. This to me says short selling. I could be wrong though.
Seems like you are benefiting from this fall in price. From my experience with hotcopper people tend to post when they are benefiting in some way. Congrats to you trader.
