Given the fact that you are shorting gold - obviously shows you are trying any way you can to make money. Nothing wrong with trying to make money - but, according to previous posts, gold is not money so one has to wonder why you bother shorting (or even trading) of all things - gold. This suggests to me a sort of desperation in your money making style.
For me, it is just a long term store of wealth (I prefer it over property) and as a diversification. You are correct when you state "price movement should be irrelevant" to me. It is. I am not in gold to make money ... I have already made that ... ages ago ... and it wasn't on gold!
Good luck with playing the gold market Dr. I look forward to you also posting your losses.....
