XAUUSD BUY OR SELL based on NPF Data ?

I am interested in both BUYING and SELLING. If price retests at 2047.35 , I will take a sell. If price breaks resistance zone at 2049.92, I will take a buy.
If NPF data above 170k -- USD strengthen (BUY)
GOLD Weaker(SELL)
If NPF Data below 199k -- USD Weaker(SELL)
GOLD strengthen (BUY)
