Check out Sharekhan's Trade Tiger. It has multiple chart windows, (8 is max I think) though I open 4 at a time. You can use intraday 1/3/5/10/15/30/60 or any intraday TF of your choice, with upto 30 days back intraday data. E.g you can have on chart of 5day 10 minutes, and another chart (on the same screen, so no need to toggle) of daily, weekly, or monthly (3 years data) in other charts. There is a minimum brokerage commitment, which varies from one franchisee to another, so you will have to bargain for it. (Also, you can have ready made templates of different tools - BB, MA, MACD, RSI, Supretrend etc running on the same charts)
