I understand the frustration and appreciate your 
service a lot. But an Amibroker customer still has a choice between several RT 
providers. It does not mention in the advertisement on your webpage that 
IQFeed does not pay you commissions or that they do not take care of business. I 
my opinion you should not offer IQFeed to Amibroker clients. A customer can 
not judge about all these problems. All I see is a fancy RT provider and a not 
so fancy RT provider that is cheaper. I usually like not so fancy and cheap 
:)

  You just buy the data and that's what you pay for,
   
  Agreed 100%. 
  But could you please tell me, if you are just 
  paying for the DATA alone, shouldn't you expect the QUALITY data 
  ?
  I mean NO BAD TICKS, reliable API, no ZERO prices 
  sent in OHL fields during pre-market hours, etc ?
   
  Why everyone expects the developer of the 
  charting application to fix ALL DATA 
  problems that DATA VENDOR should fix in first place?
   
  Why am I forced to implement hundreds of 
  workarounds to make IQFeed data usable ?
   
  Why IQFeed sells the same data 2x cheaper to 
  QuoteTracker?
   
  Why don't they implement ANY fix to their API for 
  over one year from pointing out all problems ?
   
  Why should I spend enormous amount of time 
  working on IQFeed plugin considering the fact that it generates ZERO REVENUE 
  for me ?
  ( I didn't receive ANY commission from IQFeed 
  )

    ok thanks for the explanation. 
     
    Possibly I am switching to eSignal Premier 
    though ... The thing with eSignal (what I think is annoying) is that I 
    wish they would sell just the data for a good price. Now you get charting 
    and all kind of scanning stuff that we program ourselves in 
    Amibroker and other stuff like news you actually do not want and 
    ofcourse this is included in the price. That is the nice thing about IQFeed. 
    You just buy the data and that's what you pay for,

      now we have the old bug again.  I know this experience 
      ;-)Open & Low of last (rightmost) bar is now always 0 again, 
      when thebase-interval is daily.Well, as a workaround I'll try 
      if it's possible to install Amibrokertwo times, each installation with 
      a different version of the IQFeedplugin.To Ed: The important 
      thing to note here is that data withbase-interval daily  does NOT 
      contain any bad ticks.   Your QQQexample was a daily chart 
      generated by compressing 1 minute bars.  Ofcourse, if you 
      compress bars with bad ticks (garbage in), you getagain bars with bad 
      ticks (garbage out).But if the backfill is done with daily-bars 
      (instead of minute data),there is no spike problem and the data is 
      wonderfully clean.    Whichmeans that with IQFeed one 
      would be able to look at clean dailycharts, updated in realtime 
      without any spikes, if only the plugindidn't contain any logic errors. 
      The fact that daily data doesn't have bad ticks has something to 
      dowith how the IQFeed historical data architecture is working: 
      dailydata is NOT generated from tick data (so it cannot include bad 
      ticks),but minute data is.> It implements bad data 
      filter which is based on ATR (average truerange).> The filter 
      is turned ON by default and uses 9-bar ATR of High-Low range.> If 
      next bar High-Low range exceeds X times ATR then this bar dataare 
      filtered> to eliminate spikes.> > You can control 
      both averaging (ATR) period and X (the detectionthreshold)> 
      from File->Database Settings->Configure.> > You can 
      also TURN OFF the filter already by going to> File->Database 
      Settings then clicking CONFIGURE button andUNCHECKING "Enable" flag in 
      > "CONFIGURE" dialog.> > Please note that filter by

      than I planned (I have planned towait for bad tick filter in 
      IQFeedyes, filtering on the plug-in level doesn't make much sense 
      as youneed all individual ticks instead of ticks in aggregated form 
      (=minute bars).Therefore instead of the ATR-filter, it would 
      be very helpful if theplug-in was simply working correctly when the 
      base-time interval is daily(see rationale above).Btw: 
      Maybe Jay Froscheiser from DTN Market access is following 
      thisthread.  This problem with the IQFeed plugin underscores why 
      Istrongly argued for making IQFeed's API publically available 
      (withoutthe $300 licencse fee).Even though I'm busy with a lot 
      of other things I have to work on, Icertainly would be interested in 
      developing an own IQFeed plug-in forAmibroker which could also be 
      released to the public.   (I would dothe plugin development 
      in Java, however, and TRY to do the integrationwith Amibroker via 
      Java's JNI interface, the latter would be thehardest part.)  
      What's more, the plug-in development could ideallyeven be an open 
      source project, hence allowing a peer review of thesourcecode and in 
      turn better elimination of bugs!).best
