your settings allow two simultaneous positions. But this does not mean you
will always have two positions at the same time because it also depends on
the buy and sell signals. If you have one position and there is not another
buy occuring during the first few bars then the system will only hold one
position until it encounters another buy signal and it will add another
position.
This is the only thing I can think of,
