Dear Support,

I run several strategies on one account, trading several currency pairs.

I wish to add a code snippet which closes all EURUSD positions on Friday 2100 to avoid margin calls (but not the other pairs).

I have tried the below code, which doesnt seem to work:

           
       for (IOrder orderInMarket : engine.getOrders()) {
            Calendar tradeDate = Calendar.getInstance(TimeZone.getTimeZone("UTC")); 
            tradeDate.setTimeInMillis ( orderInMarket.getFillTime() );
            int tradeDay = tradeDate.get ( Calendar.DAY_OF_WEEK  );

 if ( (orderInMarket.getState().equals(IOrder.State.FILLED)) 
            && (Day == Calendar.FRIDAY && Heures ==21)) {
                orderInMarket.close();     
}
}   

Can you help me?

Consider taking last tick time instead of current system time, as it is done in the following examples:

Mind that if the market is closed then you won't be able to close the orders - you need to do it before the market closes.
