Connecting to API (IQ Feed) to retrieve historical/live data VS loading data from QCollector?

[zwangerz]

Okay. I would need to look into how I can do that. Can IQ Feed store their data in *.csv format? As of now, my application only loads *.csv files, I think. Might be that I do it like this for now, but consider other solutions for a future upgrade.

Still, the same question arises:

Connect directly to API and load/rip off data directly or get the data from a file I download locally to my computer and skip the API Connection?

You're right about what you're thinking: My application does have to wait for QCollector to update the file. However, that happens very fast and is not a problem at all for me. I've tried doing the same kind of update after-hours/manually and it's the same.

Best regards,

You have to check if your data arrives in you application fast. Doesn't matter if qcollector updates its files quickly, this could happen repeatedly and your app infrequently gets the chance to read the data because it is being updated and thus locked by qcollector.

If you can get your hands on the API documentation it should be fairly straight forward to replace the file with a direct connection from your app to iqfeed
