PRT price inconsistency with market prices

  I’m having a similar problem. Data from indices does not match actual market data. For example, daily opening and closing data on from the following sources for the NIKKEI on 23 July, 2019 is not the same (it’s every date not just that one). In some cases the gas are quite large. Anyone any ideas why?

  Yahoo

  Open: 21425

  Close: 21620

  PRT

  Open: 21422

  Close: 21697

  More than likely it’s the broker spread that is giving the difference?

  Where is the PRT price from …  Spread Bet?

  Yes, it’s coming from spread bet.

  The spread may account for the gap on the opening price but the difference on the closing is way too high.

  I wonder if Yahoo and PRT use different closing times? Let me look into that.

  IG / brokers often widen the spread overnight / market closed to something ridiculous so if anybody trades then the broker makes tons!

  Yes please, report back what you find out about closing times etc

  What is the broker please? Are you comparing the share price from Yahoo with a CFD instrument?

  Hi Nicolas

  I’m comparing the price from Yahoo (link) with the Spread bet Index ‘Japan 225 (DFB)’. But it’s the same for any index. Sometimes the prices get pretty close but sometimes they are a long way off. The close for Japan 225 (DFB) on 23rd July is a good example where Yahoo has it closing at 21620 and PRT has the close at 21697 (which is different to the close on IG, which was 21705???).

  Regards

  James

  Check if you have the rollover applied or not in the platform settings and if you have applied custom trading hours to that stocks list.

  Hi Nicolas

  Not sure about the rollover, where do I apply that? I doubt that is the issue to be honest. I have worked with both custom and non custom trading hours but still have the same issue.

  If you take a look at one of those historic sources and prices I quoted before and then try and match that up with your PRT graph data do you get a close match? (a close match in my book being less than 5 points).

  FX does seem to have the same issue but I haven’t looked in detail at any discrepancies there yet.

  regards

  James
