I had an old TWS and as a consequence, on Friday, API was disabled by IB for that version of TWS.
Then I upgraded to the newest TWS version on Monday. Now JBT says contract ZC for exchange ECBOT does not exist. Same for ZW, ZS, but not for CL, ES, NQ, which are loading normally. What is the reason for this? -- You received this message because you are subscribed to the Google Groups "JBookTrader" group.
