XAUUSD - Is it still Valid For Short?

I'm looking at the 4H time frame. in my opinion gold is still valid for short. Have a look at the candle it has make bearish engulfing candle and now market is retesting 1780. If the price close below 1780, i'll look for short on sell zone but if the price is close higher then 1780 then this idea is no longer valid...
