but my question is
being a small trader, do we really need very very accurate data.
are we so expert
I personally value it immensely ...will pay more for accurate data.
The amount of money we are putting at risk with each trade nothing compared to 2k per month for datafeed...

well bro
will you please explain a bit or in detail, what difference it will make, if there is slight difference in price in data
or
to say that data is not very very accurate

may be I am missing something big

For positional or swing trades, NSE Bhavcopy is more than one needs, but for trading on any time frame less than a day, without a spot of doubt, YES - it is of paramount importance irrespective of being a small or an expert trader. While day trading on 5-15 minute charts; patterns, indicator calculations (for e.g. VWAP) with wrong data goes for a toss which in turn might affect trading signals. Because a shorter timeframe trader is always on the lookout to capture a bounce from a critical price level for entry/exits. Hence, correct data makes the difference.

To give you a perspective, below is a GIF from NEST for MCX symbols - have observed the same phenomenon with multiple brokers in NEST. Even when you download the DataTable for historical backfill, you will see the same inconsistency in AmiBroker. Also it is needless to mention the platforms provided by our leading discount brokers. Day trading is worse than going to a Casino in our country because of our tech giants.

Have tested and worked on NEST/NOW backfill RTD every single day for 7 months now but after trying out GDFL, somehow my charts appeared prettier. Infact I never noticed a Maribozu while using NEST/NOW RTD but with GDFL they are so evident with other common price action patterns. So it is forcing me to let go "jugaad" and vouch for a "pro" datafeed. If you can ignore this and still be consistently profitable in short term trading, then you are an expert ;)
If you go through the thread we have already made conclusion on this ...
Short answer we cannot compare datafeed as everyone gets a subset of all the ticks..
And nobody provides TBT feed becuase it is very costly.
Thanks, I get that but a bit confused among so many data providers in today's market. Should I go for TrueData or GDFL or with anyone else hiding in the hood? No need for TBT, only good accurate real-time data is what I am after. Please guide.

Thank you

sorry bro
you are comparing chart of wrong data, this is wrong data and not accurate data.
while I have asked to show me difference with accurate data and very very accurate data.

further
let you post GDFL data for a day for BNF or RIL 1 min or 5 min for a comparison.

When you ask for a comparison between "accurate" data and "very very accurate" data, the ideal comparison should be done between DOTEX data and TBT data. As we know that TBT is not available for retail participants, so we have to go for a comparison between what's available! So, what do we have? Honestly in simple words, free (missing ticks inaccurate) data or paid (somewhat accurate) data, because IMO "accurate" data should be TBT and "very very accurate" data should be TBT without any Tick loss - like our foreign counterparts use, pretty much hypothetically speaking for us.

If you compare all available free sources for data, then NEST/NOW Historical 1 minute is best. But if you are saying NEST or NOW Backfill is accurate, and think it can be compared to GFDL data, then I have nothing to say.

Trying to show a simple comparison, instead of getting into too many facts on how your indicator signals might get affected because of missing Ticks resulting erroneous data. Hope it helps !

Last week I used to think the same way that NEST DataTable's Historical 1 minute is accurate and can ignore little whipsaws but I was terribly wrong, there is more to it and even more which we still do not have. As further we move in time, as our markets become more liquid and efficient due to increased participation even DOTEX will become erroneous in due course of time and TBT will become a necessity.

What a circus our exchanges make out of thin air? There is a lot of discrimination. According to these institutions, Retailers should not participate and leave the Big Boys do their own job. All the odds are deliberately stacked against us, my friend !

Coming back to my initial query, which Data vendor should I choose for AmiBroker as of today? I am really confused between these authorized vendors.

@CougarTrader only choice is gdfl or truedata I think they contain less errors than broker feed ...based on my experience ...
we badly need a true tbt data provider in india ..till then nothing we can do
Thanks.... Also data cost is very high compared to what US or European based trader would pay for data feed.

ha ha
But
You posted data for BN (and not BNF, that I asked for, as BN data I am using is not from NEST) for NEST and GDFL
Even if I say that both data (that you posted) are same, then either you wont believe it or will say that I am desperately trying to prove my point.

So, let you post your NEST and GDFL 1 min data for BNF (BankNiftyFut) for 1-2 days
