A few problems, somewhat related...
Summary: Inconsistent use of exchange. The portfolio column "exchange" lists CMEMINI (for @ES#C), whereas the
"Charts / Timeframe" does not list it by the same name. The closest match is "CME Globex." I don't know if this is an oversight, or intended to be that way.
Summary: Cannot add "Mid-day Breaks" to "Charts / Timeframes." I had noticed that "CME Globex" listed "Active Market Hours" from 5:00 PM to 4:15 PM, with 1 break from 3:15 PM to 3:30 PM. What about the break from 4:45 PM to 5:00 PM?
Summary: As you watch @ES#C throughout the day, the graph begins to show a shaded section representing "after market" trading hours, which is very nice. However, the shading disappears whenever you restart a graph (i.e., when historical data is requested for a backfill).
Summary: The graph y-axis (price) labels seem to be missing. It is difficult to estimate prices without incremental labels, or at least tick marks, present. Please see the attached PNG screen capture. - could not find an attachment option, sorry.
Summary: There is no way to see the pricing of prior tick bars on the graph. Placing my cursor on the tick/bar of interest does not yield information about that tick/bar (i.e., OHLC or at least some price).
I'm also seeing IQfeed disconnect with a "multiple instances" warning today. The only difference between today and yesterday is an update to Medved Trader. I've not yet isolated this; it seemed to start doing it after playing with the "START/STOP" feed toggle button, which I've reported in another thread.
Thanks...
