As per the technical analysis there was a death crossover in gold at the higher levels around 29th sept and thus result is here the downfall was expected and done accordingly, well being a technical trader I can assure you one thing that I do admit and give values to the news and fundamental prospects but I am more confident on my technical charts and indicators and be very sure that the charts know everything going to happen and some drastic moves can also be identified with an eagle eye and volumetric analysis. All the best may be some one here can answer appropriately better than me but this I what I wanted to comment over your question.
