XAU/USD 800pip long opportunity I took today, first time

I watched this pattern progress from the 09/09/15. It had already reached the retracement of 0.50 at B. As soon as it broke over the 0.50 on the C to D leg I entered, just as it rallied.I neally bottled out at 0.786 to tell the truth.But I kept the faith till 0.886. I'm now looking at the possible short position.
