Or Linux.. but why not on Mac? If I'm not mistaken the problem OP is experiencing is w/ the new "Desktop (native)" version... not the Java based TWS/IBGW. @Ates, is there a specific reason you need the native version (besides cosmetics)?
windows is an universal platform for all trading apps. unless you trade as a hobby, just use the right tool without worrying it will work or not.
TWS is very easy. Logon, click on option trader, enter symbol, click on ask, change price near to the model price and transmit to market. Right click on column headers and configure. Add model price between bid and ask.
Right, but it doesn't crash (as much). Hammers have been nearly the same for a long time now too... why switch to one that shatters all the time? Lol
