Dare to say something I usually wouldn't say:

Ether 4370 is a must-give position, so now going long won't get you in, just take profit at 4370.
After 4370, I don't know whether it will go up or down, so I must exit my long position here. Continue to short at 4425 with a 40-point stop loss.
4250 continues to hang on, but reduce the position a bit. If it rebounds to 4315, then run. This position is without loss, and if it drops to 4100, adding one hand can exit.
