Hello, As API8 is bringing a lot of interesting new features, I decided to install it. As you may know, installing a new API generally means problems with software, in particular for those using TWS.OCX (the Visual Basic ones) as the one using direct socket programming are in general ok. So here is what works with API8 : - IBData 1.5 - Dynastore LE 2004-05-05 - IBCharts 1.7 - Autotrader 1.25a - Bracket Trader 04.0316.04a (initially 04.0316.04 didn't work) - Future Trader 2.61c if you install the FT API8 update - ZerolineTrader What doesn't work : - Ninjatrader 3.027 : he uses \JTS\TWS.OCX : support of API8 in NT 4.0 (so not planned for a long time!)... In the mean time he doesn't plan to pack TWS.OCX in the software package and refer to it instead of JTS one in order to be independant of API version. Feel free to add software that don't work to this initial list!
