Can someone just explain what the point of historical bid ask is, how much is given in comparison to a broker data feed and is the whole point that the bid ask is recorded after rollover. I am assuming bid ask that is recorded by platforms such as sierra from broker data feeds just records this as it comes.
Is there any use in using historical bid ask intraday or is it more just to gage level from previous months / weeks.
I see people on here being referred to gomrecorder. I am asking about historical bid / ask - yes dtniq feed supply it but I want to use it not from dtn iq because it is too expensive.
I am *** in not using historical bid / ask for cumulative delta, market profile or footprints ?
Or am I only *** if I can't get the data from the previous months?
Or does historical bid ask just sit as a superficial benchmark for saying that this datra feed is good in terms of bid ask data.
I am really confused. Do all broker feeds therefore not give accurate volume as well based on not giving historical bid ask ?
Can you help answer these questions from other members on NexusFi?
Historical bid/ask means the ability to download/store/access the inside bid/ask (L1) data aligned with price ('Last').
Without this, you don't know if a trade was executed at the bid, or at the ask, which is important for some types of analysis.
IQFeed offers historical bid/ask for download. It means if your platform supports it (Sierra Chart for example) then it can backfill your charts as it downloads "normal" data, so for the studies that require bid/ask info it is present (for example, cumulative delta). NT7 does not support this, which is the entire reason GomRecorder was created.
To populate GomRecorder data, you have to leave your computer on 24/7 or download the files uploaded in Elite section.

when you say iqfeed supports historical bid / ask for download, is that considered superior to a broker feed such as rithmic because the rithmic feed may only have a months backfill of bid/ask?
Is it also considered superior because broker data feeds to the tick are not as accurate as iqfeed or is bid / ask to the tick only recorded with iqfeed?
( or does it depend on platform )
Assuming that it becomes awkward to get previous months bid/ask data from a broker rithmic feed if you dont select the feed to continue over at the rollover I guess iqfeed also seems superior in that respect since you can download it. Is this correct to conclude?
Assuming I turn on a platform like multicharts or sierracharts everytrading day - can the data be just as good as iqfeed if the platforms server or my server ( computer ) just records that data and by 'just as good' I mean to the tick as accurate or less than a minute.
Unless something with Rithmic has changed drastically, they do not offer historical bid/ask backfill. They offer limited tick data, but that is not the same as bid/ask.
You can read all the existing threads on futures.io (formerly BMT) that discuss IQFeed vs other data feeds. IQFeed is superior as a data feed. Rithmic is not a data feed, it's an execution engine first and foremost.
Recording data on your computer is most certainly not just as good by any stretch of the imagination. Platform restarts, internet hiccups, any downtime will be a gap in data.
It's really pretty simple. If you are an average retail trader using average tools, then your broker supplied feed is probably sufficient. If you are trading for a living and want the best, then $100-150 a month in data fees is a no brainer and is close to 0% impact on your bottom line.
with market delta charts then. Why do they even have a rithmic, oec, infinity feed if all eveyone uses it the dtnma backfill - is that thing almost instant to check bid / ask in the footprint or do you request it everytime you check the chart.
I will get round to trialing dtn with the discount to see the difference by checking multichart footprint.
Is cumulative delta more accurate in checking the exact bid / ask historical feed than footprint.
