Not sure how this guy does it but here's one idea for you which I am working on right now, just trade for first 3 hours of London or New York open. Watch the 1 min charts when you see a sudden surge forward by a pair(thats the big boys jumping in) then wait for first pullback on 1 min chart and enter on trendline break of that pullback. If the big boys follow through you will get a nice litrtle trade. Secret is not to go for too many pips on 1 min charts just take 10 pips profit with a 10 pip stop.
Basically all you are doing is watching the move start then jump on board on first pullback. Simple but effective. Just don't be too greedy.
How do you know what the banks do? That would be interesting. I am actually watching a person on facebook, who claims they know what Goldman Sachs, HSBC, Barclays, big banks do. Seems like you guys do the same things. Please let me know! And he trades in the direction that they go.
