I have a portion of my paycheck put into Strike every other week.  About 75% is set to auto-buy at that moment.  The other 25% I buy when I think there is a little dip.  I've got some funds sitting waiting to buy, but it seems expensive.  Will we get another little dip (even if brief) or do I need to buy now before it goes up more?  I don't know, so I keep putting off doing my buy.  If I don't see a dip in the next day or two, I'll probably just buy.
