I have another limit buy @15.17 (61.8% retrace betw 17.64-13.65); but I'll remove it tonight.
My current long @15.65, I'll follow your advice and trail a stop @15.10
Hopefully, it heads the other way (UP that is - VBG). I was looking at 16.41 to be its strong resistance (50% of the current down trend); but I think your 61.8 @16.15 is now more important <GGG>
