That is the exact big problem technical analysis has.
This happend this morning :
"Gold Slumps Most In 2014 As "Someone" Dumps $1.37 Billion In Futures At US Open"
You can't do numbers lines, support levels, technical levels, analyses, voodoo, whatever when somebody on a Monday just dumps $1.37 bil in futures at US open.
Actually Gold was pretty text book. Failed monthly A up. Today made a pretty clean intra-day A down. I had no number line confirmation in Gold so there was no reason to be long. I'm not sure what different it makes if someone dumps 1 billion in Gold or a hundred dollars in Gold.
