I recommend that you have a account so that you are following the GC contract absolutely live. I believe the pit opens at 8:30 EST. and closes at 2:30 EST. The GC contract trades about 22 hours a day. I do not recommend trading to the individual investor. Put the account on simulator and leave it there.
Follow the daily price action TREND and only trade in that direction scaling into your position on a five minute candle. At times the GDX will diverge to hit stops. This is generally soon after the open, so scale into the position if you are day trading. Yes, sometimes it just tears away and leaves you in the dust, so that is when you want to wait an hour and scale in on a pullback.
Price action is caused by external real world events such as FOMC meetings, , political conflicts and monetary distress worldwide. These are legitimate concerns that turn investors to or from the safety of gold .
Holding a large position overnight is not recommended and is only to be done with risk capital.
I have noted on the chart the swings that I have traded in the last eight weeks. As of this writing I have a short position in GDX .
The metals finished with an above average volume green candle, but the price did not hold.
Keeping our ears to the ground for any bad news, otherwise staying short.
