As far as I heard, Tradier.com offers paper trading but Etrade.com does NOT. Paper trading is probably, with no money (with funny money), and most is same as real account such as API program, etc Which other brokerage offer this kind of paper trading? Hopefully, there might be many brokerages WITH API, together with paper trading experience. In partucular, the API developers like to see on-line documentation to study the APIs, even without opening account. He does NOT like to spend real money for testing API for me.
