英镑/美元简单突破系统 (GBP/USD simple breakout system)

Hi everyone,
I have too many systems I made myself, some are technical and some are mathematical, I'll try to post here in this forum the mathematical ones

I came out with a very simple breakout system for GBP/USD
All I have to do is to check the high and the low of the previous day
For eg the high and the low for the last Thursday was (high = 1.9660) and (low = 1.9769)
I place 2 orders as follows
Buy entry order @ 1.9960 TP 1.9965 (Yes 5 pips only) I'm using 5 lots
Sell entry order @ 1.9769 TP 1.9764 also using 5 lots
It's 90% + profitable system, I backtested this system from September 2005 up todate
I had 381 win and 26 loss
Maximum loss in every month didn't exceed 2 losses
Avg loss per month = 1 loss
There are months which don't have any loss, for eg April 2007, all executed orders made profit, no loss
I guess that noone will like this system, since I'm risking my account for a daily 5 to 10 pips only, but at the end I got my money in my pocket again
I'm a pip collector so I'm trying to do any system to gain pips even if it is risky and nonsense, no profit without risk

My orders for Monday are:
Buy entry order @ 1.9842 TP 1.9847 X 5 lots
Sell entry order @ 1.9759 TP 1.9754 X 5 lots
Stoploss is at your choice
Best regards and happy trading
