At the National Commodity and Derivatives Exchange (NCDEX), sugar for delivery in July month edged up by Rs 4, or 0.19 per cent to Rs 2,159 per quintal with an open interest of 29,800 lots.
Likewise, the sweetener for delivery in October contracts traded higher by Rs 2, or 0.09 per cent to Rs 2,207 per quintal in 38,380 lots.
Analysts said fresh positions built up by speculators after pick-up in from bulk consumers and retailers mainly helped sugar prices to trade marginally higher but adequate stocks position on higher supplies from mills restricted the rise.
