[amibroker] Rotational Mode Code Question

["Matt" <rochemb@xxxxxxxxxxx>]

I have a system that currently trades 2 postions on the last trading day of every-other month (last day in Feb., last day in April, etc.).  See code below.

I am trying to modify code so that the system enters one position at the end of every month and holds that position for 2 months.  I want system to hold max. of 2 poitions as in original code.  It would be like this: December 31st - evaluate Rank and enter 1 position.  Hold this position until February 28.  January 31st - evaluate Rank and enter 2nd position.  Hold this position until March 31st.  February 28, 1st postion is exited and new position entered and held until April 30th.  This process repeats (system enters a new postion every month, holding max. of 2 positions).  Can this type of code be done in Rotational Mode?  Thanks.

Current Code:
SetBacktestMode( backtestRotational );
Filter = 1;
SetOption("MaxOpenPositions",2 );
SetOption("WorstRankHeld",2); 
PositionSize = -100/2; 

newBiMonth = Month() != Ref(Month(), 1) AND Month() == 2 OR Month() != Ref(Month(), 1) AND Month() == 4 OR Month() != Ref(Month(), 1) AND 
Month() == 6 OR Month() != Ref(Month(), 1) AND Month() == 8 OR Month() != Ref(Month(), 1) AND Month() == 10 OR Month() != Ref(Month(), 1) AND
Month() == 12;

PositionScore = IIf(Rank < 0, 0, PositionScore); 
PositionScore = IIf(newBiMonth, PositionScore, scoreNoRotate);
