Scorpion,
the problem i found with the trading on timing is that most brokers during news hour will either not fill the request at the right time or make the spread huge. If both of these things didnt happen I could make a very hefty amount of money as well, but unfornately brokers won't make it happen..
I noticed also Ravique you mentioned that price wasn't important but I think what you mean is that you need to see the time before the price, usually prices fluctuations dont happen so randomly and are according to times (such as market open, news releases, etc).
If we want to trade with time we need to trade outside of news releases (because of increased spread and order fill) or just find a broker with fixed spread that will fill the order instantaneously!
