The TradeGuider VSA methodology will work in any market it is not specific to any market or region. TradeGuider does not provide any of the data, our VSA add-ins work with other trading platforms to provide our VSA methodology.
The data is provided by the trading platform, or, data providers each of the different trading platforms support. You can see the list of trading platforms we currently support here: https://tradeguider.freshdesk.com/solution/articles/33000228767-what-trading-platforms-are-supported-with-vsa
We have found that NinjaTrader 8 with Truedata or eSignal can supply the NSE data for the Indian market. There may be other options and we recommend that you research each trading platform and their data providers to see which one would work best for your needs.
