Only time can tell whether your decision is right or wrong. While I thought of advising you to DCA, since I am not sure of the amount that you want to invest, it might indeed be right to just wait for the right timing and make the most of your money. And that right timing is up to you.

I'm curious, do you have a specific price target for your buying or do you just rely on this buy and sell index? I don't trust this index of course, but to each his own.
