How to make the EA open only one trade long and one trade short a day, even if the entry conditions occur again in tha same day?

just the same question as mine. It's mean you only want to trade in one trade per bar and hold until the next bar...is that right? see my thread How To Make Trade Until The Next Bar After Closed? maybe you can add the code they gave me to your EA. I'm still confuse how to add to my EA.
