A little help with Share $$$ trading

Thought I might give this a shot.

Does anybody invest in shares here or know anything about share trading. I am basically looking for somewhere where I can get current OBV charts of shares for free. I am currently using yahoo finance australia but I can't seem to find the OBV charts there.

Help please

I use National Online Trading. Sign up with your Bank and it should have charts, up-to-date info, etc
