供讨论的倒卖系统 (A scalping system for discussion)

I originated this system 5 years back. a few people around me know. Now i share it and want to see more opinions.

I analyzed trading hours, and from the simple facts that Forex is 24 hours trading and there is a gap of 2 hours after US close and Tokyo opening. Yes, it is Sydney hour but observing the movement of E/U pair in this 2 hours let me conclude that it is ranging with a very high certainty. within this 2 hours, which is 5am to 7am Singapore time(GMT21-23), there is rarely any important news to cause big movement.

The pair will be confined within Bollinger Band. the profit in pips are most of the time single digit, but risk is small so leverage can be high to net a nice gain. a disciplined trader can get 15% return a month by trading 2 hours a day, 4 days a week.

i always trade 5 mins chart. Bband is 14,2,2, 1 or 2 trades within 2 hour period, highly leveraged.
