带范围的两个方向网格 (Two Directional Grid w/Range)

I've found a new strategy with grid system...

I modified the grid system with 2 direction (buy and sell) with a range

example :

GBP/USD 1.9775 we put buy..
so with 25 range we put sell, buy, sell, etc above 1.9775
alse with 25 range we put sell, buy, sell, etc below 1.9775
here the position

...
1.2050 sell stop
1.2025 buy stop
1.2000 sell stop
1.9975 buy stop
1.9950 sell stop
1.9925 buy stop
1.9900 sell stop
1.9875 buy stop
1.9850 sell stop
1.9825 buy stop
1.9800 sell stop
1.9775 start here buy
1.9750 sell stop
1.9725 buy stop
1.9700 sell stop
1.9675 buy stop
1.9650 sell stop
1.9625 buy stop
1.9600 sell stop
1.9575 buy stop
1.9550 sell stop
1.9525 buy stop
1.9500 sell stop
...

this system reduce the explotion if the price goes very up or goes very down without any retracement...

Any thought about it will be appreciate...
