India guar futures opened up on Wednesday due to short-covering after a three percent fall in the last two sessions.
However, prices quickly turned negative due to weak demand in spot, analyst said.
Spot market traders postponed buys hoping that the tepid level of export demand would bring more price falls.
At 10:15 a.m., January futures NGUF9 on the National Commodity and Derivatives Exchange were down 0.38 percent at 1,575 rupees per 100 kg.
