"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available.

We have released new version of S#.Data (Hydra).
Every version we improve the design and make the Hydra more friendly and powerful:
1. Options support! Hydra now show options desk, volatility (implied and historical). Or can evaluate it uses historical data.
2. Wanna smile? Enjoi!
3. Importing now extremely easy.
We hope the changes will useful for all algorithmic traders, including you. Please do not forget - the software is http://stocksharp.com/products/download/]available for free!
http://stocksharp.com/products/hydra/]Hydra</a> is a free application for downloading and storage of market data.
Hydra supports great choice of market data sources. It this topic will explain how to download the history from most popular sources: IQFeed service.
To begin we tell a little bit about the program interface. After the first start you will see the main window, which prompts you to select the data sources.
Pay attention to the description of each source, if the following is written next to it:
Source is designed to get history data … - then it means the ability to download historical data,
and if the following is written:
Source is designed to get market-data .. - then it means the ability to connect to the real-time data source and one's own history collection. Looking ahead, a similar process is often cheaper than a simple data purchase from a data vendor.
Now select the number of sources and try to get the market data. As such, we propose to use: IQFeed (as a source of real-time data with the maximum number of concurrent subscriptions).
Click the check-boxes in the selected sources.
After you click OK, the program prompts you to enable additional features.
They are well documented in the program itself, so we will not go into a description of each of them.
In order to move forward it will be enough just to click OK without selecting anything in this window. If necessary, you can always restore this setting via the ADD -> Tools button and select the required.
After all the previous procedure, we have got added sources in the left pane, all of which must now be set up.
IQFeed supports a very wide range of parallel subscriptions, as well as a much greater depth of history, both for candles and tick data.
The CandleFromDate parameter is needed to specify the starting date from which you want to download the history in the form of candles.
The TicksFromDate parameter is needed to specify the starting date from which you want to download the history in the form of ticks.
Now, after all the manipulations, you need to understand, and how to work with these data, and what the program can do else. Recall that data is stored in the directory where you downloaded them, but how to see what is a result.
Next, similarly we select Level 1, and then Candles 1 min, but in the window with candles we do not choose the magnifying glass, and Chart button. The results are shown in the figures below
That's the way you can view the data and work with them directly from the program.
We hope our product will help you in trading and development of profitable trading systems.
