Thai rubber futures ended mixed on Friday in thin trade as most investors were on the sidelines waiting for a clearer market direction, brokers said.
Overall volume dropped to 23 RSS3 contracts from 41 contracts traded on Thursday, brokers said.
The December, March and April contracts ended flat and the November contract rose 0.20 baht to 51.20 baht per kg, brokers said.
"Trade was sluggish. Some speculators sold contracts to take profits," said one broker. "Players are struggling for the market direction."
Brokers said prices could rise in the next week, in line with the physical market, with the next technical resistance at 51.50 baht and support at 50.80 baht.
