Jeez.
In a similar time frame forex can make you $1bn. or $1. Depending on your position size. Just like oil. Look at daily ranges for forex vs oil and you'll see that generally forex is much less volatile, but people trade it in much bigger size because brokers allow more gearing. And that's because in % terms its less volatile. So all people are doing is increasing their position size to compensate for its relative lack of volatility. Which is why some people appear to win big, usually shortly before they blow up in a manner even Spanish would find impressive.
Assuming by PST you mean US West Coast, then the London morning session 8am-1pm is equivalent to midnight to 5am, so good luck trading it and carrying on with a day-job.
