Replace direct calls with global dictionaries

1 The purpose This project is to modify two applications. The current communication between two applications is using direct reference-call and call-back. We need to use global dictionaries to replace these two calls. • IBSampleApp of InteractiveBrokers (IB): this is a windows application sending trade order of stock, or option to the TWS API of IB. • TWS API: this a windows API receiving orders from IBSampleApp. TWS is windows application acting as order router. There is no need to modify it. 2 What should be modified 2.1 The current communication flow: o Clicking “send” button of IBSampleApp by a user will call(a reference call) a method of TWS API directly to send order from IBSampleApp to TWS API o TWS API will send order to TWS o TWS will send order to server of IB o When order status is changed, server of IB will call TWS o TWS will call TWS API o TWS API will call(callback) IBSampleApp to update order status on GUI. 2.2 New objects should be added: o Two global dictionaries(GD), and two vectors o GD_TStoIB: a GD which has a vector, V_TStoIB having order data o GD_TSfromIB: a GD which has a vector, V_TSfromIB having order status data o Add an event handler of GD_TStoIB in TWS API to get order data IBSampleApp o Add an event handler of GD_TSfromIB in IBSampleApp to get order status data from TWS API 2.3 New communication flow: o Clicking “send” button of IBSampleApp by a user will store order data into V_TStoIB which will be added into GD_TStoIB o Event hanlder of GD_TStoIB will fire in TWS API and get order data o TWS API will send order to TWS o TWS will send order to server of IB o When order status is changed, server of IB will call TWS o TWS will call TWS API o TWS API will store order status data into V_TSfromIB which will be added into GD_TSfromIB o Event handler of GD_TSfromIB will fire in IBSampleApp to update order status and show them on GUI. 3 Requirement of your skills • Familiar with API • global dictionary • Familiar with stock, and option trading • Familiar with C# and VS 2017
