Volume means activity. These volume spikes concern me - something happened. While I will never find out what exactly that was, judging by the fact that the first spike occured almost on the very top (left shoulder, even before I was bearish on this pair - which makes sense) and that we have just had the second spike at the bottom, after the pair fell considerably, I suppose... someone made a lot of money. Now why this someone has just closed his/her profitable short here? I guess he/she knows something. But what?
Actually I really want cable to drop to 1.35 and below, if possible. Sorry, good people of the UK. Hi, Mr. Soros!
P.S. Spikes like these can also be found of other pairs. And put together they make little sense ;)
