Being an Indian citizen, I would like to trade in US stock markets (i.e. in NASDAQ and NYSE)
Is that possible?
Quite a few stock broker in India offer to trade in US markets via tie-up brokers in US. As an Indian citizen, there are limits as to how much FX you can buy, generally very large, should be an issue. The profits will be taxed in US as well as India [you can claim relief under DTAA]
