In conclusion, it would help to indicate exactly what the evaluation cri-
terion would be to the broker. This will hopefully ensure that the execution
was completed as intended. The possibilities are
1.Conservative trading. Ensure that there is at least one way to pair the
trade list such that each pair satisfies the spread criterion.
2.Aggressive trading. Ensure that the average spread achieved is the same
as or better than the specified spread value and therefore to the extent
possible the speed of execution matters.
