in the XAUUSD Gold Structure is the Bullish because :
in the 4H structure, after reaction to the DE Order Block, the structure in the 15min has changed.
note: after reaction in the Order Block we can use this formula: 4H LPP = 15min CHOCH
of course in the 15-minute chart, the structure changed from bearish to Bullish because the 15-minute CHOCH has been completed.
this is just my idea you can test it.
Be successful and profitable
