I dealt with this issue a while back, but I believe I remember the
particulars:
If your position exits, then re-enters on the same bar based on the logic
that MP = 0, a Signal "knows" that you went from say MP=1, to MP=0, to MP=-1
all within the same bar. To an indicator, you simply went from MP=1 to
MP=-1. Indicator logic doesn't detect the MP=0 condition intrabar.
Which is very ironic considering that it's the Indicator that you can choose
to have evaluate "tick by tick".
Hope this helps,
Gene Pope
