placeOrderModify

The placeOrderModify method replaces open order with new order.

Syntax

var placeOrderModify(previousOrder, newOrder);

Parameters

previousOrder

Valid Order object instance filled with information for an existing order.

newOrder

Valid Order object instance filled with information for a new order.

Return Value

This method returns true if order was placed successfully, false otherwise.

Remarks

In order to replace existing order with a new one, validate that previous order contains a valid orderId.

Example

The following example demonstrates the use of placeOrderModify method. The code attempts to modify all open limit orders by $0.01.

function start()

{

//retrieve short positions for all symbols

var account = getAccount();

var placeOrderModify = false;

//determine whether order modify needs to be placed

//if orders need to be modified, find limit orders, and modify their limit prices by $0.01

if(placeOrderModify)

{

//get all open orders

var orders = account.getOrders();

//modify all limit orders

for(var i = 0; i < orders.length; i++)

{

//if limit, then modify

if(orders[i].getOrderType() == ORDERTYPE_LIMIT)

{

var prevOrder = orders[i];

var newOrder = new Order();

//copy previous order into new order

newOrder.setSymbol(prevOrder.getSymbol());

newOrder.setOrderType(prevOrder.getOrderType());

newOrder.setActionType(prevOrder.getActionType());

newOrder.setTifType(prevOrder.getTifType());

newOrder.setQuantity(prevOrder.getQuantity());

//modify limit price by 0.01 if possible

newOrder.setLimitPrice(prevOrder.getLimitPrice() - 0.01 > 0.01 ? prevOrder.getLimitPrice() - 0.01 : prevOrder.getLimitPrice());

//submit order modify request

var rc = account.placeOrderModify(prevOrder, newOrder);

}
