On February 27, 2010, DTN implemented new symbols containing 2 digit year codes. We have reproduced their email below to explain what they have done. It is very easy to load these new symbols into NeuroShell, however, because DTN software does that for you. After downloading the new symbols, you will have to use the new symbols in your charts before DTN expires the old ones in 30 days.

Before you download the new symbols, we think it might be best to make a backup copy of the old ones first. Just make a copy of the following folder:

C:\NeuroShell Trader 5\Servers\IQFeedforNST

To download the new symbols to NeuroShell, first close down NeuroShell. Then run the DTN program IQfeedNSTsetup.exe which is in

C:\Program Files\DTN\DTNforNST

by double clicking on it.

Here is the DTN email:

“We just wanted to remind you that 2 digit year codes are being rolled out tomorrow, Feb 27th 2010 to all IQFeed servers. This will affect all future, future options, and spread symbols. At this time, the symbols will change from using a single digit year code (example: @ESH0) to using a two digit year code (@ESH10). This change is being implemented because many contracts are starting to trade more than 10 years in the future.

Here are a few more examples of how symbols will change:

Old Symbol     New Symbol     Description
CH0            CH10           CORN MAR 2010
@ESH0          @ESH10         E-MINI S&P 500 MAR 2010
@ESH0C112500   @ESH10C112500  E-MINI S&P 500 MAR 2010
QGCJ0-QGCM0    QGCJ10-QGCM10  GOLD 100 OZ APR 10/JUN 10
NGF0           NGF10          NATURAL GAS FUTURE JAN 2010
NG1F0          NGF20          NATURAL GAS FUTURE JAN 2020

In order to ease the burden of customer support issues (needing to migrate symbol lists, workspaces, watchlists, etc), the old 1 digit year codes that are currently in use on Feb 27th will continue to work for 30days following Feb 27th, 2010.

It is VERY important that you make sure your software is compatible with the change before that time in order to make sure you and our mutual customers are unaffected by this change when the old symbols are discontinued.”
