統一回答: the direction of the big move

Some DQers sent me private chats regarding the message I post at 2:56pm, somebody even complaint that I did not provide the direction of the big move. 

Actually I did not know the direction then, it needs the market itself to give out the direction. 

However to catch the direction is not difficult. Go below the purple line, short. Go over the green line, long. Eventually market choose to tumble down. Then next is to computer the target when to close the short position:

A->B:  3262 ->3249 = 13

P->C : 3254 - 13 = 3241

The lowest is around 3239.
