The only clear breach of support in gold's ten year trend line continues to be in 2008. And even that was brief.
2008's breach was followed by an accleration of the trend - an increase in the support line's slope. It could easily be argued that we're due for another such occurrence.
Note that I said the only CLEAR breach of support was in 2008. But the blue line I drew could be construed as another support line which was breached, in which case the comparison to 2008 and its aftermath is even more apt.
Just something to think about....
