Look at this long term digram of XAUUSD from 2002. It is obvious that this Gann Fan supports and resists to the XAUUSD from 2002 till now.
Specifically the 0.5 of Gann (green dashed line) has operated as a support and resist in the past .
So I think that nowadays 1070-1085 is the support zone in long term of the XAUUSD and perhaps a temporary bottom. Yesterday XAUUSD touch this support line and reacted immediately.
