Folks,
Just playing about with some charts and Fib numbers, I think I have come up with some very useful MAs for gold.
Look at the weekly chart below. See how often it bounces off the 55 week moving average - major support - and the 13 week MA when it's really flying.
Then when it trends down look how the 5 week MA provides resistance.
Here it is in close up:
On the basis of this we can expect weekly support at 612 with major support just below 600.
