i have a large database of stocks, futures, rates, fx. if there is interest i could set up something.

 

I'd be interested. What source is the forex data from?

Thanks,

thats really cool.. on the downside they dont have forex or futures data

 

The name is Tickdata, actualy they don't have any tick data

 

I'm using IQFeed / DTN.IQ. They have good API. But they limit the amount of days you can go back.

 

?? Actually, tick data is exactly what they do have if we are talking about www.tickdata.com. I have purchased a lot of data from them - they are very good & provide high quality product but are also quite expensive

 

Tickdata don't have quote data, they have traded price for tickdata only. I mean like this

I have two emails from tickdata.com confirming that they don't have it.
