Magic number is just a number (1, 1234567, 20130405.) You include it when you open a order with orderSend. Later you can find all open orders with a OrderSelect loop and filter by symbol/magic number to find just the EAs orders, not other chart's/EAs.
 

i see. thank u kronin and WHRoeder. i understand this.
