Has anyone using IB TWS standalone have experience being filled with out first receiving "acknowledgment" in the audit trail, and as a result never have the orders or subsequent orders appear as filled on the platform? This happened to me with 3 trades on 05-03-11 on ESM1 into the close, being executed but never receiving confirmation of the fills. Any other similar unreported fills executions with IB TWS? Thanks for some in put here.
