I am a binaryoptions trader and mainly So if i go for subscribtion, i have to consider below. Do I get live and historical data without spread? Does paperbrokerage support binarypaper broker. Is there any way i can store my algorithmn processing calculations(not backtest) on some workspace? Documentation explaining email and mobile notifications. Is there a way I can use algirthmn to send me notifications(call/put) instead of holdings. I hope i get some answers.
