[amibroker] Re: WorstRankHeld Help



PureBytes Links

Trading Reference Links

On last day of month I want MaxOpenPositions and WorstRankHeld at 3, which I have.  I do not want scoreNoRotate for other days in the month.  Rather, for other days in the month I want WorstRankHeld set at 15, leaving MaxOpenPositions at 3, so that system will rotate if any position held drops to below 15th in the ranking.  How do I do this?

The idea is to buy on the last day of the month the top 3 ranked and to hold them until the end of the next month, but only if the ranking does not fall a large amount (say, to 15 as I stated above) during the month.


Thanks

Bert
