SWP API

Developers can use SWP API to integrate Stock Watch Pro with their own applications. SWP API allows you to capture orders originating from Level I, Level II, Charts, or trigerring alerts. API broadcasts a window message with a string containing order details. Your application can listen for this message and parse the order string for further processing.

Click here for the source code of a sample application which listens for Stock Watch Pro messages and prints out order details. It registers to listen for SWP_ORDER messages using RegisterWindowMessage() and processes them in OnOrderMessage() handler. The order string is passed as an atom in wp parameter of OnOrderMessage() handler. It is retrieved using GlobalGetAtomName() and then parsed to retrieve the order info. The order string consists of field=value pairs separated by semicolons. Here is a table of fields and their common values:

Field Description Values
Symbol Symbol for which the order was initiated any string
Action Whether buying or selling Buy, BuyCover, Sell, SellShort
Qty Number of shares any number
Order Order type Market, Limit, Stop, StopLimit, FOK (Fill or Kill), any string
Price Order price any double
Route Order routing Default, SOES, SelectNet, ECN, any string
MM Market Maker or ECN any string
Expire When the order expires Day, GTC (Good till cancelled), any string
StopLimit Stop limit price (optional) any double

An order can be initiated using one of the following methods:

In Level I window, double-click on Bid cell or Ask cell to send a sell or a buy order respectively. Right-clicking on any row pops up a menu that allows to send an order for execution.
In Level II window, double-click on Bid list or Ask list to send a sell or a buy order respectively. The symbol of Market Maker you clicked on is sent as part of the order string.
"On Alert" field of Alert Settings window allows to setup an order for execution when that alert is triggered. When alert is triggered, check "Send Trade" option to send the preset order to be broadcasted to other applications.
Right-click on a chart to send a sell/buy order via API:

To enable API messages, go to the Trading tab of Preferences dialog (click on Edit --> Preferences) and select API from the dropdown list. Click on Settings button to configure API options:

Specify the Order Type, Route, Market Maker, and Expiration for orders originating from Level I and Chart windows (Trade Method), Level II window, and Island Book. Values can be selected from the dropdown or user-defined values can be specified. Level II and Island Book methods can be disabled.
For orders originating from alerts, specify whether the trade message should be sent only after the alert dialog is acknowledged or whether it should be sent immediately (useful for automated trading).
