The rupee appreciated by 10 paise to 82.93 against the US dollar in early trade on Tuesday, tracking a positive trend in domestic equities and foreign fund inflows.

Forex traders said the rupee is trading in a narrow range as the soft US dollar and positive domestic markets provided support, while concerns over global economic slowdown and rising expectations of a rate hike by FOMC amid strong economic data from the US may cap sharp gains for the local unit.

At the interbank foreign exchange, the domestic unit opened at 82.93, registering a rise of 10 paise over its last close.

On Monday, the rupee closed on a flat note at 83.03 against the American currency.

In initial trade, the rupee also touched a low of 83 against the greenback.

Somaiya further said "we expect the USDINR (spot) to trade sideways and quote in the range of 82.80 and 83.20".
