Quote from dlonET:
What happens when you your IB TWS or you computer looses connection, and with IB TWS happens alot, you need SierraCharts, as it will fill up your gap and keep you data intact. NT, even with products like CQG, cannot do it.
Quote from NinjaTrader_Ray:
You are correct, NinjaTrader will not backfill with IB when working with bars that are built from ticks. This is because IB does not support historical tick data.
