Hi @CougarTrader I tried checking this particular issue with IB support as well. The hourly chart on TWS has issues. The first candle is 9:15 to 9:30 and then the rest of candles are 9:30 to 10:30 and so on..i was checking for NFITY...they said its by design and i need to raise a feature request. I said, what the hell!! this is basics of charting. Do you see the same ?
