NEW YORK/LONDON, May 20 (Reuters) - Arabica coffee futures on ICE turned a shade higher after touching a six-week low on Tuesday, on heavy position rolling out of the spot contract as market participants awaited more clarity on the extent of crop damage in top grower Brazil.

Cocoa trading on ICE Futures U.S. and Liffe rose to three-week highs on chart-based buy signals while sugar prices were little changed.

July arabica coffee futures on ICE KCN4 rose 2.20 cents, or 1.2 percent, to settle at $1.8570 per lb, in heavy volume dominated by July/September spreads KC-1=R .

"The majority of the activity we're seeing is longs rolling forward so that puts a little bit of selling pressure into the market," said Julio Sera, senior risk-management consultant at INTL FCStone in Miami, referring to earlier weakness.

Benchmark coffee prices KCc1 are down around 15 percent from April's 26-month high of $2.19 a lb, supported by concerns over the outlook for the Brazilian crop following a drought earlier this year. The bulk of Brazil's arabica crop is expected to begin harvest in June, when a clearer picture of damage is expected.

"There has been quite a significant pullback from the April high, but I don't think it is due to anything fundamental," a London-based coffee broker said, adding that volatile speculative-driven price swings will likely continue while crop uncertainty persists.

Liffe July robusta coffee LRCc2 eased $1, or 0.05 percent, to end at $2,036 a tonne, quietly trading well within Monday's range.

In cocoa, the most-active July contract on Liffe LCCN4 closed up 18 pounds, or 1 percent, at 1,857 pounds per tonne and July futures on ICE CCN4 settled up $38, or 1.3 percent, at $2,968 a tonne. Both contracts rose to the highest levels since April 30 and closed above their 100-day moving averages for the third straight session.

The ICE contract marked an outside reversal on Monday, exceeding both ends of Friday's range and closing above it, which attracted chart-based buying today, dealers said.

"The smart money has been running short the market," said Eric Sivry, head of agri options brokerage at London-based Marex Spectron. "So? Why not cover? Why not lock in some profit, given that the Bali conference chatter (last week) was not that friendly?"

Talk of higher world production pervaded the market following the Bali cocoa conference, potentially shrinking an anticipated global deficit this season.

Raw sugar futures extended losses late in the session as the market corrected lower following last week's volatile swings. The ICE July raw sugar contract SBN4 closed down 0.19 cent, or 1.1 percent, at 17.58 cents a lb.

August white sugar on Liffe LSUc1 eased $4.70, or 1 percent, to finish at $477.70 a tonne.
