SC Team - As you currently don't store bid/ask information as part of scid and during replay though T&S data can be extracted, it doesn't include true bid ask information. This is making it a bit difficult to build a tool and to fine-tune as It can't be replayed back (exactly in the same way - which includes - true level2, depth updated, bid/ask information).

In case of Ninja - there are replay files - which pretty much includes everything for this purpose and can be used in replay mode.

Probably this is the only thing that I miss in SC compared to Ninja and is making it a bit difficult to fine tune tools in SC that depend on depth updates/ level 2 information.

Is it possible for you to provide - FULL replay information ( bid/ask / level 2 / depth updates ) for a single instrument and that too for one single day - that can be used with SC ( Symbol ES ). Potentially you can think of using DTC client/server for this I would imagine.

Would you please review and consider this replay for a single day/single instrument that can be used to replay repeatedly as needed?

Hope you consider this as a genuine request.

Thanks

Not sure why you say this. We would expect you would have seen the new feature which stores bid and ask data with every tick. Refer to:

SC team - I am referring to BidSize / AskSize ( not type of trade ) which are not stored in scid.

All I need is full market information for a single instrument and for a single day ( or even for an hour ) - that I can replay multiple times to fine-tune piece of code. Though it's not really a show stopper - in it's current state ( where I can't replay the full information ) is certainly not ideal.

Appreciate if you can think of a way to replay - a single hour of data - for a single instrument - which should include BidSize/AskSize/Depth Updates records/Level 2 information.

Thanks

- T&S data during live
http://screencast.com/t/DZrXYCywjUh ( notice all real numbers for BidSize & AskSize )

- Same data during replay
http://screencast.com/t/g40wTqSO3RRJ ( notice all 1's for BidSize & AskSize )

- Also during replay - there are no Depth Update records ( Type -- SC_TS_BIDASKVALUES )

- Also during replay - level 2 information is not available

Certainly understandable - due to the complexity of this and I would find my way around it.

However - being a developer yourself - imagine - lack of "repeatable" data (however small it is) and it's impact on building quality tools.

- thought of building my own scid file(using live T&S data) - which can be used for this purpose(would have solved part of the issue) but you don't want to add the fields bidsize/asksize to scid file(whether you populate or not). So there is absolutely no way for me to replay WITH true bidsize/Asksize information.

upcoming feature: Bid/Ask Price & AskSize/BidSize Data | Post: 37653

Thanks
