Trade Hard, sure I'm interested in trading signals, but have a strong dislike of and distrust for "black boxes" -- i.e., if I can't rip it open, see inside it, and verify not just that it works, but why it works, then I have no interest in using it.
Also, I don't believe in letting anyone make my trading decisions for me, (and I don't think anyone else should do so either), so I pass on any and all subscription signal/trade-alert/etc services as a matter of policy.
