So how do you handle future IB API changes? Are upgrades covered in the price? Source code available?
hello, not sure what do mean with changes ? if you mean rollover, you can define a rollover day offset relative to expiry. upgrades are free within same major release 1.xxxx TWSLink installs various samples that demonstrate usage. so much source code provided (TradeStation, excel, MetaTrader, perl,c#, vb.net, eSignal, etc.)
Don't you bother to read the websites you posted at the start of this thread? The page at http://www.trade-commander.com/twslink/twslink.htm says "Supports all features of InteractiveBrokers API 9.3." IB TWS API 9.3 is a year and a half old. IB has since released APIs 9.4, 9.41, 9.51, 9.6 and 9.62. Your software should at least be up to date with the previous API version of 9.6. Traders don't want to pay for old software.
thank you for pointing me to this. in fact features up to 9.62 are implemented except: - Required validation... (9.62) - RTVolume Generick Tick.. (9.62) - IBALGO orders support (9.6) - Reuters fundamental data request (prepared and coming soon) (9.51) - Delta neutral Combo orders (prepared, coming soon) (9.51) (so, up to 9.41 completely and above missing some) if you urgently need one of those features above, please let me know. allow me a hint: TWSLink comes in addition with various useful features not provided by IBs API like - extensive logging - trailing orders, executions, account values - odbc database support (predefined sqlserver2000, access, mySQL,... databases to track orders, executions and account values) - global parameters - sending mails - and other it's primary goal is not to implement EVERY sophisticated feature of IBs API once it is available (finally we do it). it's major purpose is it's general usability in a easy, realiable and performant way
