I attempted this Israeli system by a great forexer called O.Bar.

Attempt to open 2 positions, through stop/entry order - in the exact same rate!!! E.g. :
buy gbp/usd 1.2031 and market gbp/usd in the exact same period(hedge).

Very important : I use a stop of 20 plus a trailing stop of 10 (the Delta is 20).

When the two positions open I perform exactly the following :

The place I trail the stop manually with a 10 pip stop - And I wait patiently for a radical break that stops the losing position and continues my winning commerce - functions most of the time only on GBP/USD - london session (based on the big ben platform).

Use THIS only in peak overlap occasions - and :
Most importantly - I use Two Oanda accounts on this system - because the spread is minimal - hence - a reduction is minimal at best.

This system functions best at the London breakout session .
How can u guys improve it?
