I have found some mismatches on decimal placement for the current last quoted for various Grains as well as E7 between your/CME's website's charts and quotes and the OEC Trader Demo.

"your" website means:
- http://www.openecry.com/trading/trading-hours.cfm
and other OEC pages like
- http://www.openecry.com/trading/specifications.cfm
that point to the supported symbols and their hyperlink.

I go from there to the documentation for a given symbol, say, Corn (ZC). This is of course actually the CMEGroup's documentation:
http://www.cmegroup.com/trading/agricultural/grain-and-oilseed/corn_contract_specifications.html

From there I go to CME's web page for the symbol's quotes:
http://www.cmegroup.com/trading/agricultural/grain-and-oilseed/corn_quotes_globex.html

or to the symbol's CME web site chart (link to chart is embedded in CME quotes web page).

Whether or not I select the OpenOutcry quotes or Globex quotes, CME quotes Corn Mar 13's last as: 701'6.

However, in OEC Trader demo, the quote and chart for Corn Mar 13 give its last as: 7.0175. Note: the last quotes are different because they are from yesterday (CME web site) and today (OEC Trader Demo). This doesn't matter, I'm just looking at decimal placement.

So the decimal placement is different between the CME-provided quotes and charts and the OEC Trader Demo's quotes and charts by two digits.

This decimal placement mismatch occurs for these symbols, all Grains except E7:
- ZC Corn
- XC Corn, mini
- ZO Oats
- ZL Soybean Oil
- ZS Soybeans
- XB Soybeans, mini
- ZW Wheat
- MWE Wheat, Hard Red Spring
- KE Wheat, Hard Red Winter
- XW Wheat, mini
- E7 Euro FX, mini

The CME's decimal placement matches that of quotes for the same symbol in various other sites and trading platforms, such as:
- thinkorswim
- http://www.barchart.com/commodityfutures/Grains
- http://www.admis.com/QuotesChartsNews.aspx?page=default
Note: the OEC Trader Demo's placement of the decimal seems to be unique from all other quotes for the same symbol (and same exchange of course).

Would it be possible for OEC to adjust the decimal placement for these symbols' current Bid/Ask/Last, aligning them to what the symbol's exchange is quoting?

For example:
- Corn quote in OEC Trader Demo is: 7.0175
- Corn quote in CME web page is: 701'6
- Adjusted/new quote for Corn in OEC Trader Demo would be: 701.75
Note: again, the lasts are not the same because they are from yesterday (CME web site) and today (OEC Trader Demo), but what's important is the decimal placement.

The reason why I request this is because OEC Trader Demo is showing the same quotes we receive from the OEC api. Thus, we show to our users a quote with a different decimal placement than what the exchange is giving, as well as and other platforms and web sites. This can cause confusion for our users.

Thanks very much,
Chris

The data formatting presented in OEC trader is how we receive the raw data. You may convert the price format with the Custom Price Format feature:

If you are using a custom application, you may handle fomatting in your expected format.
