For daily chart, it look 46.20 is the bottom, my first target is 49.

Brexit post a big spike on gold. I was thinking of Soros. He knew Britons.

From James Joyce's Ulysses, the Martello tower,  Citizen, the ordinary people, xenophobia. It's a fact, Brexit is a fact now. The mind can detect this! But not me, because I am too depend on Computer (or technology), that's why I lose the touch with the mind.

It looks to me trading is not about technology, so meditate, reciting the mantra, reading James Joyce & Joseph Campbell, walk in the nature, to have a touch with the mind!

For oil, bull engulfing still have effect. In the morning it dropped, but from afternoon, it reversed after API report. (In trading, patience is number 1 factor, I have to wait the day for the trend to continue)

Gold dropped today, will Silver follow?

Silver dropped, but not under the low of previous bear engulfing, so I am still waiting!

Wait for several days, today silver turned to black. Enter with bear.

Bear engulfing does not need confirmation, today it drops very big. I buy HOU when it's under the middle line, may not be a good time. looks that bear is full in control.

Gold is in bull trend now. I sale the gold for profit, now I am balanced.

Bear engulfing for today. A signal to buy HOD. For me, just wait (to buy HOU).

Gold, bull no change. Since 1270 is the resistant point, I would think it will stay here for a while, could go up to 1304.
