    i'm trying to construct 30s bars on the fly using IB's 5s realTimeBar objects. however, the results I get are very different from the historical 30s bars IB provides through the reqHistoricalData method. i like the historical feed so it would be cool to replicate it for trading. any ideas on why the difference? i'm only interested in the closing prices.
