On the ES today the 9:30 - 9:35 5 minute candle opened at 1058.75, but the correct opening price was 1058.50. I'm a long time e signal user, but am very dissapointed by this. The free charts with IB have the correct price. Now I'm wondering why I pay more than 300 dollars a month for e signal, when I need to rely on my free charts for an accurate quote.
