i prefer the same as well, but after such a hard run, i usually put out initial small positions, on the chance that it runs hard *and* i can't short it later, so there won't be much pain. i put on the size after i see a top in place.
Or going short right here on the small trend channel break and volume change candle, $61.68 is the pivot.
AMZN, from my indicators, might get up to squeeze another, maybe final, group of shorts, at 62, 62.25, 62.75, 63; but maybe not higher than that. Just my thought, I am curiously watching, refrain myself from trading it at all.
