If we do break down from 42800, id be targeting 3800 for the check back of the break out. We could come back up and fail to make a new high, possibly giving us the beginning of a bullish bat, inside of a Bearish Gartley (posted on twitter)
42800 would be a good entry if we come back down off this impulse up, id say confirmed support there would be confirmation, with a stop under 41500 theoretically.
