Quote from whoknows?:
10% spec is $150 billion (Man, that's still a lot).
I am small, but the guy (one guy mind you) who taught me a lot about the business trades $130 million a day (roughly). Add that to mine, and between he and I we trade 10% of the spec volume in FX. Haha. That's funny. I am a piker.
10% of 150 Billion is 15 Billion my friend, a far cry from $130 MILLION!

And just because a pattern works this week, month, year does not mean it will work next week month year!
