Hi,

I am looking to build up historical options dataset for backtesting.
I am using HIT (v6.1) to collect 5 min data on option symbols. But I don't think it provides Open Interest or Bid/Ask for non trades, is there something else I should be using for the task at hand instead of HIT?

Thanks,
Manish

Bid/Ask for non trades is not available on any symbol, option or equity.

If you are back testing on that kind of high frequency data, you probably don't really need a lot of history.

I simply run collections on bid/ask/trade info live during market hours. I store that each day. There is much info.

I can then back test as needed on the details collected.

On the other hand, I'll typically build models, then run them real time on paper trading. It provides a true real-time high-frequency experience. Or as close to true, as paper-trading can supply (some slipped and unmet orders).

We do not save historical Open Interest or bid/ask data for quotes. These can be captured live and saved in a database on your side however.

Thanks Stargrazer,

My Stock strategies trades once everyday at the market open and utilize the EOD data.

For my options I was collecting bid/ask at a 60 min interval from IBKR but it was too slow and trading 10-15 min before the market close. Can you please share the command that you use for "bid/ask/trade info", also is there a way to get that info all the symbols in one request like market summary??

Thanks

Not sure by what you mean by 'but it was too slow'. But that would typically be how you would get the bid/ask, is by 'watching' the bid/ask/trade stream.

Run the 'w' with a symbol in IQFeed to obtain the live stream. You can then extract the bid/ask/trade information from this live stream.

No I get that I would get the bid/ask by watching, but using the IBKR API I took me a long time to request the data for the entire option chains of 500 or so stocks.

I don't want to request or watch them "One Symbol" at a time, is there a way to watch the whole OPRA at any given instant?? That is I get the snapshot of the whole market and go to working figuring out what is of interest to me before I ask for anything else?

Actually nevermind "5MS" already has BID/ASK...I just wasn't seeing all the columns....classic rookie mistake.
