It's a kaboom - after effect of Fed announcement

When Fed announce that they'll buy their treasury....market suddenly turn down-side up. Gold was pushed up from 892.xx to 962.xx within 8 hours.

The same goes to GU and EU.
this situation made a heir-wire to those account who trade with no SL(stop loss) mechanism.
I'm fortunate because my sell position was hit SL in green (i managed to put my SL in +ve side before got hit that day).Instead of chances to gain of 1000 pips +, i only managed to get 300+pips on the trade.Nevermind, the market is still there, just wait for your opportunity to get in trade (in correct direction of course)

Moral of the story here - never forget your MM and SL button ok.
