Hi everybody, this is my first post after being a visitor for some time. Here are the issues: 1). Sometimes when I exit the Ninja/Zen platform and re-enter it, I found that the most recent intraday ( 15-min & 30-min ) candlesticks are slightly re-adjusted to a new price ( and fixed thereafter), as if the most recent real-time price on the chart does not reflect the actual price at the exchange? Somehow the DOM looks OK and tallies the real-time live chart. Although the different is small, it makes me uncomfortable because it may affect my trading strategy. Imagine the price you see now is not the the actual price when it becomes the historical price on the chart. 2). Compare the ES charts ( similar time-frame ) between Ninja/Zen and esignal ( from futuresource.com ), prices are not similar. Isn't all ES data feed come from the same source, Globex? Feedbacks from members are appreciated.
