Hello,

From when the new syntax options will be available to the API?

MQF1017D15 -> MSFT1017D15

Thank you

As posted in the document linked in the following post:

OPRA will start consolidating these symbols in groups over the next few months (there is a tentative schedule at the end of the above document).

It looks like you can find a symbol mapping on which symbols will be converted on the following website:

http://www.theocc.com/initiatives/symbology/implementation.jsp where they make the following statement:
"The consolidation spreadsheet offers preliminary data and is subject to change. A finalized spreadsheet will be published the week of each scheduled consolidation event."

Thanks
