Quote from bigsnack:
a move back down to 1310 would essentially be a lower low (violating the low put in around 1315). If we put in a lower low and then continue down into 1305's, that's the tried and true definition of a downtrend. I'm not saying it won't go back up from there, but I would need to see confirmation that the uptrend is resuming, and then I would just buy the next pullback. So I wouldn't catch the low necessarily, but by waiting for some confirmation I can still get a good entry with little to no heat, plus I won't be caught holding the bag if it turns into a falling knife situation.
