We already did a comparison for missing tick and we found out esignal too does not provide tick by tick datafeed.
I am currently using Neotrade and I am observing many high lows which are incorrect where I have proof that the trades have taken place.
Nobody that I know of has subscribed to tick by tick data feed of NSE.
All have subscribed to L1 datafeed becuase it is cheper. Trading terminals use L2 datafeed.
L2 datafeed are perfectly fine for Trading terminal but again should not be used for charting.
All L1,L2 and L3 datafeed are not datafeed at all they are never accurate should not be used for charting. They should not be marketed by NSE and the data vendors to begin with.
It is a big fraud by NSE and all the data vendors.
Unfortunately in india sab kuch chalta hai.
Please remember you are using a approximate datafeed which is not a correct term to begin with.
