Handling multiple orders

 
Can somebody tell me how i can open one position at a time in each of the major pairs. At present i have the Orderstotal function set at <1 but this only lets one position be executed in total throughout all the charts whereas ideally i would like to  be able to have 4 or 5 positions opened each one trading a different pair. If i increase the Orderstotal to say 4 then i can have 4 positions opened all on the same pair which is undesireable if the price moves against them.
