– Installing the IDE – Introducing IBrokers package – Reference sheet for IBrokers – Viewing account data – Historical Data and Streaming data access – Sending Limit order and StopLimit order – Moving Average cross over strategy – example code

• Robustness and other enhancements

R • Quick prototyping after back-test therefore

minimal code changes required • Availability of a variety of packages

implementing statistical functions therefore no need to code from scratch

• Open source • Single Threaded

Why use R for Trading • Already are familiar with R and use it for other

steps in your trading analysis • Quickly want to test strategy to figure out

difference between real life and back testing data

Warnings and pitfalls • Risk management module in case the default TWS

risk management system does not catch all strategy specific risks.

• Test case to be written to ensure strategy does not run into order sending loops.

• Code block to ensure order price and order quantity sanity.

• Test cases to run through every time an API upgrade happens so that you can be sure that nothing is broken.

• This is real money now. 18

Robust code for live trading • Requirements

– Handling socket connection losses – Handling error messages from Interactive Brokers – Handling Network errors

• Resource available online – API doc on Interactive Brokers website – Example code available on github by other people – Implementation with 2 R instance on github by

censix (https://github.com/censix - please note this is not an endorsement of that specific

implementation and QI is not connected in anyway with the owner of the blog) 19
