TWS Improvement suggestion

    There is a flaw in IB quotes when a futures market reaches limit price.

    Outright prices( limit bid/ask ) are right but calendar spreads quotes continue to display implied( limit ) prices. In reality, when a market goes limit, CME seems to disable implied prices, spread orders start matching only with other spread orders and the spread starts to move on its own.

    It leads to largely erroneous quotes on TWS. It costed me a lot this morning as I was trying to submit non marketable limit orders using TWS that were filled instantly at the ( real )market .This fix is mandatory IMO.

    I made an error on this topic. IB calendar spread quotes are sometimes wrong when a market reaches limit price but it wasn't the cause of my problem. Just for info.:)
