Good morning community, I want to close all my position 20minutes before market close on friday night. Can you suggest some codes for my EA in order to reach my goal?

Please consider the following code

public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
    if (period != this.period || instrument != this.instrument){
         return;
    }
 
    Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
    calendar.setTimeInMillis(history.getLastTick(instrument).getTime());
 
    if (calendar.get(Calendar.DAY_OF_WEEK) == Calendar.FRIDAY &&
            calendar.get(Calendar.HOUR_OF_DAY) == 20 && calendar.get(Calendar.MINUTE) >= 40) {
 
        for (IOrder order : engine.getOrders(instrument)) {
            order.close();
        }
    }
}
