Dark pools could be about to become a little less so.
In the coming months, exchanges that operate outside public view likely at least will have to disclose trading volume, under a draft rule the Financial Industry Regulatory Authority will be submitting to the Securities and Exchange Commission in the next month or so.
The rule will call for a rundown of how much business dark pools are doing and would provide the first look into how much activity is directed to the exchanges, according to a Traders magazine report.
A draft is expected to be submitted in October or November, followed by a comment period. Adoption would come in early 2014.
