I am sorry, but I could not understand your question.
Are you referring to the data product from True Data India, which makes use of esignal "data manager software" for delivering the data into multiple trading software at the same time ? If yes, then that is just an Emulator which True Data guys are using and that is in no way related with esignal. All the data that they provide through it, comes from the data servers of True Data themselves and not from esignal servers.
Although, since both of them are Authorized Data Vendors of NSE, so both of them are receiving the same data from NSE. How exactly do they process it and provide it to the customers in real time, is totally dependent on themselves.
Regarding, whether the tick data is of same quality or not, we can ourselves do the testing by comparing esignal tick data with TrueData tick data, for any stocks. And that would clarify in this regards.
Thanks
