UPDATE 3-After trader outcry, CME pares back grain trading hours
* New grain cycle cut to 17.5 hours from 21 hours
* CME reacts to complaints from traders
* Country grain elevators disappointed with change

March 5 (Reuters) - CME Group Inc said on Tuesday that it plans to pare its nearly non-stop trading cycle for grains and oilseeds to 17-1/2 hours per session after traders complained a move to extend activity had hurt liquidity.
CME, owner of the Chicago Board of Trade, sought to shorten the trading day less than a year after adding hours in response to a challenge from arch-rival IntercontinentalExchange.
Many traders said the increase to 21 hours to 17 hours, implemented last May, had spread out volume, reducing liquidity and increasing volatility.
The longer cycle also kept futures and options markets for crops like corn, wheat and soybeans open for the first time during the release of key monthly reports from the U.S. Department of Agriculture, which often cause sharp swings in prices.
Traders formerly had two hours to analyze the reports before trading resumed, and some have called on CME to pause trading so they can digest such data.
Under CME's proposed hours, trading would still be open when USDA releases major crop reports at 11 a.m. CST.
As proposed, electronic trading will run from 7:00 p.m. CST to 7:45 a.m. CST Sunday to Friday. Trading will then pause for 45 minutes before resuming on the screen and in the historic Board of Trade open-outcry pits until 1:15 p.m CST.
Currently, electronic trading runs non-stop from 5 p.m. CST to 2 p.m. CST.
Traders applauded CME's decision to reinstate morning and afternoon pauses, which were features of the trading day before hours were extended last year.
The start of trading in the morning and close of trading in the early afternoon "have been historically very deep and liquid opportunities for trading volume, and customers are really looking for that," said Austin Damiani, broker for Frontier Futures.
CME, which surveyed customers about reducing trading hours last month, declined to say whether it expected the shorter cycle to boost volume or liquidity.
"We heard pretty clearly that there was an interest in reduced hours," Dave Lehman, CME's managing director of commodity research and product development, said in an interview. "The trick for us, if you will, was in balancing the needs of those who were happy with the existing hours with those who wanted shorter hours."
The new cycle will take effect April 8, pending approval from the Commodity Futures Trading Commission.
Managers of country grain elevators are among those who want to maintain longer hours.
The National Grain and Feed Association (NGFA), which represents thousands of elevators and processors, said a "significant segment" of its members prefer the current 5 p.m. CST start time for overnight electronic trading to the planned 7 p.m. start time.
The shorter cycle reduces the period of time that cash grain dealers can lay off price risks in the futures markets, according to NGFA.
Topflight Grain, a cooperative in central Illinois, may cut the hours it buys grain from farmers if the CFTC approves the reduced trading cycle, said Derrick Bruhn, merchandising manager. He worries he'll face more risk and plans to ask CFTC to reject CME's proposal.
Bruhn said U.S. grain dealers will suffer a disadvantage to European merchants because of the limited hours during the U.S. business day.
European traders had asked CME to shorten hours because the close of trading at 2 p.m. CST, which is 9 p.m. in Paris, hurt their quality of life, Lehman said.
AGAINST THE GRAIN
Most other major commodity exchanges, including the CME's New York Mercantile Exchange (NYMEX), have already shifted to near 24-hour trading cycles as China's rise has spurred demand for Asia-hours activity, while hedge funds and high-frequency traders have clamored for greater access.
CME's livestock markets trade electronically for 23 hours a day.
But denizens of CME's hallowed CBOT trading floor fought against nearly around-the-clock trading. More than 600 traders, analysts and grain handlers last year signed an online petition calling on the exchange to shorten the trading day.
Floor traders were largely pleased with CME's plan, long-time Chicago Board of Trade member Jerome Love said in a phone interview from the exchange's wheat-futures trading pit.
"Clearly it's an improvement," said Love. "But the floor population is generally dissatisfied with the 8:30 a.m. opening," preferring a day that begins an hour later.
The day trading session began at 9:30 a.m. CST before CME extended hours last year.
Love noted that he did not expect CME to reduce hours further.
