Here's a continuous coffee chart going back to 1996. It's has the waves marked. EW's are to subjective for me, and this is not my chart ... so take it with a pinch of salt.
We are at 25 year lows below the 5000 mark (4150 on 12/7/01) (I show the high area as 34000 on 3/77)
Catch a move like that, and you might be able to buy lunch ... lol.
