The rupee stayed on the upward track for the third day in a row, appreciating by 4 paise to 83.14 against the US dollar in early trade on Thursday amid easing crude oil prices and a weak American currency.

Subdued sentiments in the domestic equity markets and concerns over foreign funds withdrawal capped a sharp gain in the Indian currency, forex analysts said.

At the interbank foreign exchange, the rupee opened at 83.17 and then traded between the range of 83.13 to 83.17 against the greenback. The Indian unit later traded at 83.14 against dollar, registering a gain of 4 paise from its previous close.

On Wednesday, the rupee settled 7 paise higher at 83.18 against the US dollar. On Tuesday, the domestic unit had gained 3 paise against the American currency.
