Citigroup Inc. (C) was fined $150,000 by the New York Stock Exchange's regulatory arm for trading violations and related supervisory deficiencies.

Its Citigroup Global Markets business consented to the findings without admitting or denying guilty.

NYSE Regulation alleged that on four days in 2007, the company canceled 365 market-on-close orders of various securities after the relevant cutoff times. It also found that on 18 days in December and January, the firm submitted 12,480 limit-on-close orders after the 3:40 p.m. EDT cutoff time.

Meanwhile, National Financial Services LLC was fined $75,000 for also failing to abide by rules regarding the same orders that got Citigroup into trouble.

Also, NYSE Regulation fined TradeStation Group Inc. (TRAD) $100,000 for improper conduct related to odd-lot orders inconsistent with NYSE rules and policies regarding such transactions.

Both National Financial, a unit of Fidelity Investments, and TradeStation also neither admitted or denied guilt.
