Gold- Reversal could be next

I was bullish Gold since the beginning of the year and, in the last 2 days, XauUsd has risen 400 pips from the bottom to the top.
However, with a very important resistance zone between 1870 and 1880 and the fact that the recent break is from a triangle (termination patterns), I expect a correction soon.
That being said, I m looking to sell rallies in the up mentioned zone with a good R:R considering 1820 support as the target
