Hi Guys,
I am finding it very difficult to reliably pull historical data.
I am using my own integration, however the exact same behaviour is exhibited in your sample apps also.
If I request 500 (or less) ticks of data, it works 100% of the time.
If I request 0 tick of data (all), it almost never works (worked for about a 2 hour period - twice)
If I request 1000 ticks, it is the same as requesting 0 (all) ticks. In behaviour that is.
I am changing the default sort order of the data.
I am using the symbol as the RequestID
So an example request would be:
HTX,QCLG18,0,1,QCLG18
I have also tried days (10)
HTD,QCLG18,10,,,,1,QCLG18
Right at the start I was almost always receiving some data, often very delayed between chunks (30 seconds to several minutes)
Now, I don't even get a response from the servers. No data - as if the request was never sent/processed.
When it works (it has not for 2 days now) the data screams down say (1-3 MB per second)
Over the last few days I have mainly tried to pull tick data for QCLG18 so you should be able to see the request hopefully :)
Cheers
