I am new to USA. In India to trade in market one needs a Demat account and a trading account. but In USA, when I opened an account with a reputable brokerage there was no mention of an account similar to Demat. https://en.wikipedia.org/wiki/Demat_account
So my question is "what is USA equivalent of Demat account ?or it is not necessary in USA."
Or Indian stock market is unnecessary using DeMat Account.
