NINJA free data only from yahoo and google i dont know much about it.
you can get paid data extraction from terminal or server based.
data extraction from terminal is better because uses less resources than server based.dont worry about legal or illegal no matter. terminal data you have right to use as you like but not sell outside.
dont go for broker terminal software, no broker in india has good software and they are not upto the standards.
dont go for big name brokers, they will charge more hidden charges to maintain their lavish offices in every city.
