I am working with a strategy that can only deal with one filled order at a time, for money management purposes. I am trying to program a way to cancel all pending orders when one order fills. I have come up with this:

    public void onTick(Instrument instrument, ITick tick) throws JFException {
        // Cancelling Pending Orders If An Order Is Filled
        for (IOrder allOrders : engine.getOrders()) {
            if (allOrders.getState() == IOrder.State.FILLED) {
                for (IOrder order : engine.getOrders()) {
                    if (order.getState() == IOrder.State.OPENED) {
                        order.close();
                    }
                }
                break;
            }
        }
    }

Is there a more efficient way to program this?
