SINGAPORE, Sept 15 (Reuters) - Oil prices steadied early on Tuesday as traders closed short positions and took on new longs after markets tumbled in the previous session.

A broker said Tuesday's gains were mainly driven by market participants with short positions locking in profit following Monday's falls, while other traders took the price fall as an opportunity to place new orders.
Front-month U.S. crude futures CLc1 were trading at $44.30 per barrel at 0029 GMT on Tuesday, up 30 cents from their last settlement. Internationally traded Brent futures LCOc1 were up 32 cents at $46.69 a barrel.
"This morning's trading is not representative of fundamentals, but instead a digestion of yesterday's moves," said the broker.
Venezuela's president Nicolas Maduro late on Monday repeated his call for the Organization of the Petroleum Exporting Countries (OPEC) to convene a heads of state meeting and that he would present the country's proposals to shore up oil prices to the group.
Yet Middle East producers from OPEC - who effectively control the export club - have so far pledged to maintain high output in a fight to defend market share against rising competition.

Instead, there has even been growing competition amongst the lowest cost producers in the Middle East, such as Kuwait and Saudi Arabia, to undercut each other with discounts for supplies to their core markets in Asia. ID:nL4N11K241
On the demand side, Japanese manufacturers' confidence slumped the most in a year in September to an eight-month low and is forecast to worsen further as fears of a China-led global economic slowdown grow, a Reuters poll showed. ID:nT9N10I02C
