I am a full time intermediate trader who recently came across this thing called "tick by tick chart" for intraday, it seems like a lot of professional traders across the globe use this over conventional time based charts. So I was wondering if there is any trader out here on this forum who can share his experience with respect to tick by tick chart for intraday. It seems like most Indian discount brokers don't provide tick by tick charting so could you anyone please suggest a good and reliable data vendor in this regard ? is NSE live data feed and tick by tick is the same thing or not ? I got to know that some NSE real time data vendors just provide second based order snapshot data than real tick by tick data. Would really appreciate if anyone can share his overall trading experience with tick by tick charts, thanks in advance.
