Hi Raj,
I haven't worked on Ninja Trader but can do it.
I have a solution for implementing custom strategies, technical charts and generates signals based on realtime datafeed. I have developed api to capture market price from NSE terminals and send these prices on messaging framework to do furthur actions like db storing, generates realtime signals etc.
I am pretty sure, if I go through Ninja trade documentation then I can implement as per your requirement so I downloaded trial version of Ninja Trader to take its feel.
Please let me know if we can be associated to get mutual benefits.
