Gold is favored ended the cycle from 8/16/2018 lows where the daily right side is up in wave ((3)) at the 9/4/2019 highs at 1557 and a pullback to correct the cycle from the 8/16/2018 wave ((2)) lows ended wave ((4)) at 1446 on 11/12/19 where the 4 hour is turning up. While above there the metal can continue higher in wave I toward the 1700+ area before it corrects the cycle from the 12/12/17 lows.
I like they way you chose and placed the stop loss in your trade setup. Without the Iran-related rally to $1600, $1579 was a resistance of moderate strength. I would also use this level to place SL.
