gidielle Posted April 7, 2014 Report Share Posted April 7, 2014 Why are they so different? in particular the Bollinger Bands? maybe QT fix few points of MT? Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 7, 2014 Report Share Posted April 7, 2014 you are assuming you have exact same data in both - bad assumption when dealing with TICK Charts. If you want to compare, try some symbol that you backfill with the same data source, then set it to time based charts with same settings.

kui Posted April 8, 2014 Report Share Posted April 8, 2014 gidielle, what data provider are you using for futures? thx! Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 the QT chart is IB. I assume MT is the same Quote Link to comment Share on other sites More sharing options...
gidielle Posted April 8, 2014 Author Report Share Posted April 8, 2014 IB real time for QT and MT, no backfill 1 Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 @gidielle, as far as your original question, you can compare the raw data for both. That is where the difference will be. Shouldn't be in the chart. Quote Link to comment Share on other sites More sharing options...
gidielle Posted April 8, 2014 Author Report Share Posted April 8, 2014 I have seen disappear a candle in real time three time, in the points A, B and C of the image; when MT creted a new candle deleted the previous the raw data seem the same, but with a difference of 10 seconds Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 can't tell from just the top 10 tics considering that every bar is 33 ticks. If any ticks in the past are different, it would impact all ticks after them too. The bars before D look different as well, so the change would be earlier. Also, QT and MT CME GLOBEX timeframe I think is configured slightly differently, so the tick candle would start/end slightly on different tick, and thus would look different. That is why I say that you really cannot compare 2 sets of tick charts like that unless you KNOW that the data is identical and you are looking at identical settings. for example, to test, I did a TICK backfill with IQFeed on NQ in both QT and MT. Initially the ticks looked different (timeframe definition difference). I then deleted all ticks prior to midnight for today (the timeframe differences are around the start of the overnight session). This way, the data being displayed should line up. And it did - the two then looked identical - candle for candle. Here is the picture comparing (I didn't bother setting all the preferences the same but you can tell that the candles are the same) Quote Link to comment Share on other sites More sharing options...
gidielle Posted April 8, 2014 Author Report Share Posted April 8, 2014 I have explained myself badly. Forget QT. I have seen three times a candle disappear from the chart; MT has designed a candle, then has canceled it when it began the next. In the positions A, B and C there were three candles.

Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 the last candle continues to be updated as new volume comes in. It could be that new volume came in that changed the candle and caused a new candle to be started but not sure what you mean by candle disappearing. With tick charts, you cannot have an empty spot for a candle simply by the definition of how tick charts work. So if a new candle is started, whatever the previous candle is is the one that was built. It might have been changed with incoming data as it was closed, but that is the candle. You can confirm it by looking at the raw data window and matching the data. Quote Link to comment Share on other sites More sharing options...
gidielle Posted April 8, 2014 Author Report Share Posted April 8, 2014 as you can see the raw data on the right, between 3508 and 3512 there isn't the gap that is in the chart "point B". MT has create the relative candle, but then has deleted it when has started the next candle ( first candle after point B ) Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 I'm having Mike check. Question - if you just close the chart and re-open it, or open a 2nd chart with same settings, is it then showing correctly? Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted April 8, 2014 Report Share Posted April 8, 2014 if closing/re-opening the chart does not fix it, could you send us the data files/settings? to do that: go to FILE / Export Settings. Leave the checkboxes already checked, and also check QUOTE DATA Export, then email me the exported file please. NOTE: if the result file is over 10 meg, can you upload it somewhere I can get it, like http://www.zippyshare.com and give me the URL Quote Link to comment Share on other sites More sharing options...
