How to place an order within a trading strategy

The method sendOrder of the OrderService is responsible for placing Orders. This method takes an Order Entity or Order Value Object as parameter.

Sending an order using and Order Entity looks like this:

MarketOrder order = MarketOrder.Factory.newInstance();
order.setStrategy(strategy);
order.setAccount(account);
order.setSecurity(security);
order.setQuantity(orderQuantity);
order.setSide(Side.BUY);

getOrderService().sendOrder(order);

The associated Entities (i.e. strategy, account and security) can be retrieved via the LookupService.

Sending an order using Order Value Objects looks like this:

MarketOrderVO order = MarketOrderVOBuilder.create()
.setStrategyId(strategyId)
.setAccountId(accountId)
.setSecurityId(securityId)
.setQuantity(orderQuantity)
.setSide(Side.BUY)
.build();

getOrderService().sendOrder(order);
