My trading strategy requires backtesting and is based on historical tick data information. Most of my backtests run for 30 days or longer duration. We would be calling DTN IQ feed through API calls. However, when I look at your FAQ document, I see that tick data cannot be downloaded for more than 8 days during market hours.

1) What would be our options if we have to overcome this limitation?

We are thinking, if we could download the data and store it in our database that way we don't have 8-day limitation. Does this sound like a viable approach?

Thanks for your assitance.

Jbem,

Yes, you can download the data outside of market hours and store it locally.

Another option is to use minute data instead of tick data, if that would suit your needs. Only tick data is limited to 8 days historic during trading hours.
