Why don't we all just admit what's going on here with these Interactive Brokers "special symbol cases": it was a terrible design decision made by IB and the charting vendors are left holding the bag to come up with a workaround so they can be plotted just as easily as data that comes in on the LAST.
What I don't like about Amibroker's "workaround" to this problem is that it's passing on the burden to the end-user to deal with this IB abomination when it should be dealt with as a special case by the charting package (specifically, the inside the IB plugin) so that is is EASY to plot NYSE advancers/decliners and NYSE up volume/down volume in real-time. DDE? ODBC? Are you guys (Tomasz, Marcin) serious? I even heard something like using AddToComposite() as a workaround. This is not what the end-user wants. This information updates once every 6 seconds. Tomasz, maybe I'm way off base here and I just don't understand how to do it, but show me in 3 lines of AFL code how to plot the NYSE advance/decline ratio in real-time in candle plot form using the IB plugin. --- In [email protected], "Bill Schmidt" <[EMAIL PROTECTED]> wrote: > > From AB support: > "Natively it's not possible to store bid/ask prices in AmiBroker database, > so the only workaround would be to catch Bid prices in the LAST field when > using DDE plugin.
