Simply 1375 zone is critical point, turn back or still try to invade $1400 per ounce and above.
Technically, I recommend to buy if the gold price break $ 1375 per ounce and I prefer SELL now for long term.
Martingale Theory can apply in selling Xauusd,
(example, sell now 1 lot and sell again @ 1350 2 lots and sell again @ 1370 4 lots and little pullback will make huge profit but should consider the risk too)
Thank you :-)
