I think you have a couple of things going on here:

1) QuoteCenter's FX data pulls from fewer bank contributors than does XENITH's. This is the nature of FX quotes. Virtually every data vendor (or broker) will provide different quotes depending on who their contributors are. And of course, different underlying price values will result in different indicator values.

2. I believe your bands have been overlayed with different y-axis scaling. When you drop the bands, make sure you choose "Merge with scale on right".

Thanks John and Roy for your replies.
I can confirm that on both charts the indicators plotted were properly scaled. When I first saw the difference that was my first thought as well.
John's suggestion that the data is essentially different from Quotecentre and Xenith is surely not plausible. The difference in data values would have to be substantive to account for the way both bands are plotted. Indeed if it were the case then I would have no confidence in any indicators being plotted on Reuters data.
I'm going to post a close up with grid lines for both charts (leaving out the Macd) later today to see if I can more clearly identify what is going wrong with Metastock 12 and Xenith.

Thanks for suggestion Wabbit..I have two Excel files but.would seem that I do not have permission to attach files to reply.

I had a quick scan through the data and it's now pretty obvious to me what is happening especially when you look at the data records either side of record number 1427 on the Xenith data. I think this might be related to another issue I had with Xenith data which I already reported to Equis and not yet fixed. Anyway I'm interested to get your opinion. Remember data was collected from both charts set to 120min periodocity.

sorry about that, looks like it's more than Metstock v12 which is dysfunctional today. I'll check with my ISP.

Hi Koy,

It's hard to believe that all Equis staff are idiots who would do a prank like that. [:$]

Uninstall Xenith, reboot your PC.

Clean the registry, do scan disk, defragment hard drive. Reboot and re-install Xenith. [:)]

As John S mentioned, the contributors for Forex are different between QuoteCenter's FX data feed and Xenith's. This will cause some discrepancy in the data.

I think Investopedia has a good explanation for how FOREX is traded. See Page Here

"There is no central marketplace for currency exchange; trade is conducted over the counter. The forex market is open 24 hours a day, five days a week and currencies are traded worldwide among the major financial centers of London, New York, Tokyo, Zürich, Frankfurt, Hong Kong, Singapore, Paris and Sydney."

Since there is no central exchange for the FOREX each data provider will have a group of bank contributors that send data to them as trades are conducted through the bank. This means with thousands of banks trading FOREX world wide that prices can vary based on the bank contributors each company uses.

Now to the other issue you mentioned with the 2 hour charts. To find out if your issue is part of a known bug or due to something else, I would need to know more about the issue you see with the data in 12.

Do the bars change at a time you are not expecting?
~What do you expect to see?
Do you receive multiple 1 hour bars in a row followed by 2 hour bars?
~If Yes, at what time do you see these 1 hour bars?

What are your Start & End times for 12 & for QuoteCenter
In MetaStock 12, when you right click in your chart in a blank area, and go to Chart Window Properties, and then to Trading Sessions, what are the Trading Session times listed? In Which Time Zone are the times calculated?

In older versions of MetaStock you find this by going to File - Open, then typing the symbol in the Open Dialogue under the QuoteCenter tab and right clicking on the symbol in the list above the symbol box and selecting Properties. With the older versions of MetaStock all times are based off the timezone & system clock settings on your system.

If the trading sessions do not match this could also cause some difference in the calculations as the bars would change at different times, and give different calculations for the Bollinger Bands or other indicators.

Hopefully you find this information helpful, and it will help us track down the differences you see to the extent for which the differences in the bank contributors can accommodate.

Hi Koyasan

This is part of a bug that has been reported previously. I know that the engineering team is looking into this issue, but we have no ETA as to when a fix will be released. I apologize for any inconvenience this issue causes you.

I see the updated version has not addressed this bug so the matter (and this thread status) remains unresolved. Fix this and give me the same quantity of intraday data I had with Quotecenter and I'll gladly sing the praises for V12. Sad thing is you are already half way there with Eikon being such a great source of data info and more user friendly than Quotecenter but in the end I need to rely on the charts to trade.

Thanks John for the update. Personally I think the real issue here is transparency and trust. There are technical issues with Metastock V12 as there is with any charting software and that is acceptable. What is not acceptable is having to spend so much of my time searching through the Forum for answers or having to convince you guys to acknowledge there is even a problem. My suggestion, which I would kindly ask you to comment on, is to use the Product Alerts or devise a new category thread such as Known Issues & Bugs to inform the Metastock users about Known Issues & Bugs and how they are being managed. You already have the information so why not share it?

This model of working with customers is just normal industry standard and being transparent about issues will do no harm to the reputation or otherwise of Metastock. On the other hand lack of transparency just frustrates customers and in the long term undermines confidence in the product. Just my 2cents worth.
