Gold- To flag or not to flag? (short term outlook)

After a bad last week, with the price dropping around 800 pips, Gold found support above 1780 and has managed to finish the week above important 1800 figure.
The price is just under 1815-1820 zone resistance at the time of writing and looks bullish so far.
On the other hand, this rise looks flag-ish and could only be a correction to the previous drop.
Is important for bulls to maintain 1800 intact and confirmation of reversal comes with a break above 1820.
I'm bullish but cautious on the yellow metal
