[Sticky] - Important Update: "SC Data-All Services" Symbol Cleanup

[2020-05-08 12:40:53]
Sierra Chart Engineering - Posts: 90526 | Ending Date: 2021-04-05
We have worked with the data provider Barchart for a long time now and the symbology used for SC Data- All Services is based on Barchart symbols.

These symbols in many cases are absolutely terrible/horrible to say the least. In some cases they have no relation at all to the true symbol set by the exchange.

This creates confusion and a very poor impression for Sierra Chart especially for new users.

CQG also does not have good symbology but this is another subject and those will not be changed.

And there are also separate categories for searching for spreads and options. When this needs to be just integrated in with the primary listed symbol as we have done with the SC order routing service.

Gradually we will be cleaning this all up.

For example instead of DYU20 for the EUREX DAX we would use FDAXU20-EUREX.

We are making an announcement about this because it will require coordination with users. Once we start releasing these changes it is going to require users to update the Symbol Settings and translate the symbols (Edit >> Translate Symbols to Current Service).

We may not do any release of any changes for several months from now since we have other priorities.

Thanks for making an announcement about this. Just would like to confirm:
Please post *any* relevant information regarding this, before the changes are applied.
Me and the members of my private group are very heavily using custom symbol settings and chartbooks based on Barchart's symbology, with sometimes hundreds of symbols used/defined with custom settings.
Thanks in advance & regards, tt

Yes of course we will. This will be well coordinated.

We think the best way to approach this is that we will create the new symbols and keep the old and new for a period of time.

This will be the least disruptive. It allows us to begin anytime and just work on this gradually at our own available pace.

We are starting work on this now and the changes will not be disruptive to the existing symbols. The new symbols will exist for a period of time along with the older symbols.

And we will also be working on allowing searching for spreads and options directly using the primary listed symbols and not a separate category of spread and option symbols. How this will work is documented here:
https://www.sierrachart.com/index.php?page=doc/SierraChartOrderRoutingServiceWithData.php#Symbols

The older symbol listings for searching for spreads and options will then be removed when the new method is fully supported.

We should have all of this complete in about two weeks.

We have released the new symbol format for the SC Data-All Services Service in Sierra Chart for the following exchanges:
CME
CBOT
COMEX
NYMEX
EUREX (Finally very sensible symbols for EUREX instead of the absolute utter nonsense that Barchart has)

For these exchanges there is now this new method to search for spreads and options:
https://www.sierrachart.com/index.php?page=doc/RealTimeDataFeedsAvailableFromSierraChart.php#ExchangeTradedSpreads_NewMethod

So there is no longer a separate symbol listing for doing searches which was really disorganized.

To utilize the new symbols, use this Edit menu command to translate the symbols:
https://www.sierrachart.com/index.php?page=doc/EditMenu.html#TranslateSymbolsToCurrentService

The old symbols are still maintained and are listed in File >> Find Symbol under categories that contain the text (Old). We will be removing these within about 30 to 45 days.

This sounds great!

I have just used the 'Translate Symbols' function and seemingly - at this time - the new format is available for CBOT symbols only.
It is expressed by the new '-CBOT' addition to the symbol name and the availability of the category '...CBOT (Old)' but I do not see this available for the CME, COMEX, NYMEX, EUREX symbols yet.

Is there any other setting that I need to adjust? I'm currently using the 2177 version - do I need to update to the 2178 pre-release? Or the new symbols will automatically available?

One additional question: after the old symbol formats will be finally removed, will that break compatibility with old recorded market depth data that was saved using the previous symbol format?

Follow the instructions here to update the Symbol Settings:
https://www.sierrachart.com/index.php?page=doc/GlobalSymbolSettings.php#UpdateSettings

And then translate the symbols after.

You will need to rename the data files, to the new symbol format. This is all.

Release 2179

1) Please can you confirm that intraday data files (.scid files) got new naming style and historic daily data files (.DLY files) maintain old naming style? For Eur Fx future I got 6EZ20-CME.scid and E6Z20.DLY. Is this ok or naming will coincide and then this will be changed in the future?

2) Using "Translate Symbols To Current Service", SC download again intraday data, why do not rename existing .scid files? So now I have 2 files, old E6Z20.scid E6U20.scid etc... and new 6EZ20-CME.scid 6EU20-CME.scid etc...
Can i delete old naming .scid files, right?

TY

You cannot use the old symbol format and the new symbol format at the same time. Only one symbol format can be used.

Once all symbols are updated to either the old or the new symbol format, then reconnect to the data feed:

I don't know if this answer is for my question in post #9.
Anyway, to clarify, I understand that only one symbol format can be used, and it's ok.

The problem is that if I request a long term continuous historical daily data for example for New Zealand fx future 6NZ20-CME, SC populates data folder with one 6NZ20-CME.DLY file and a lot of N6xnn.DLY (old naming style).

The fact that there is a mix of new and old naming style is right or something is wrong and you need to tweak something?
Or maybe it happens only on my PC?

Information about new symbol format:
https://www.sierrachart.com/SupportBoard.php?PostID=237095#P237095

Yes this does make sense in the case of continuous futures contract charts:

The problem is that if I request a long term continuous historical daily data for example for New Zealand fx future 6NZ20-CME, SC populates data folder with one 6NZ20-CME.DLY file and a lot of N6xnn.DLY (old naming style).

It is important that when using the new futures symbol format, that all symbols for a particular futures contract are consistently that format including symbols you are using in sub instances.

After changing the symbols you need to reconnect to the data feed:
https://www.sierrachart.com/index.php?page=doc/FileMenu.html#ProcedureToReconnect

We made some improvements to the Edit >> Translate Symbols to Current Service function to ensure the translation is always to the new symbol format and avoiding mistaken translations, and to also translate the Intraday File Update List symbols. The only case of a mistaken translation that we are aware of involves the symbol GER30 where it would be translated to a Eurodollar (GE) futures symbol. This has been prevented and is in the latest prerelease 2181.
