API 2.8.0 standalone. What is the significance of this message?

Do I need to configure a logging level? How to do that, please.

HyperScalper

We separate Ticks/Candles history on two parts:

1. latest history, for ticks its last hour.
2. earliest history - all other existing history.

Those two history parts are stored on two servers: latest history server and earliest history http file server.

First we look on http file server to load the history for the client.
If the history is the latest and if there is no such file on file server, but it theoretically should be there (in practice some time is needed to create file) we show mentioned WARN message.

As you can see this is exactly your case - it is now 2013-11-05 15:00:07.178, but you need file for /2013/10/05/14h_ticks.bi5.
Our file server had not created the file yet - only 7 seconds had passed.

You should not get too concerned about this warn message, because you'll get the file as soon as it gets created.
