Today there is no trend. I guess what I learnt is to ignore sudden spike/dip. I shorted first at 1534, then watched it go to 1539. I hold on and watched it go back to 1534.5 and closed with 0.5 point loss. I then tried to long at 1533.75 but it wouldn't make new high and went back from 1538, so I closed at 1535.75. I watched a while, switch again to short and gain only one point. Well, it's really a narrow range day in the afternoon.
Next week is OE. Watch and wait.
