Lean Data Feed

I'm seeing a lot of signs that indicate that this platform is one that I can make great use of, however I'm not seeing a lot of documentation that will assist me in getting up and started and some of the questions I have are seemingly basic.

Can you detail exactly how to execute the toolbox project?  I'm looking to use data from Google but I can't figure out how to execute the toolbox project in order to pull down data and have it curated for the QC Lean local project.  I'm more comfortable with developing within Visual Studio because intellisense allows me to explore portions of the infrastructure within the confines of the immediate class file.  Given the lack of documentation beyond using some of the canned solutions this seems like the best way to go.

 

Any help you can provide will be greatly appreciated. I'm ultimately looking to scan a universe or data set and identify items above a certain volume rate of change.  I want to use this as a way of getting my feet wet before fully automating trades.

Hi Jim! Thanks for your feedback! Feel free to shoot questions through here and we'll answer then ASAP.

To execute a toolbox project right mouse button on the project in Visual Studio and click "Set as Startup Project". Then right mouse button on it again and click Properties. In the Build tab you'll see a "Start Up" class selected which sets which main method you'd like to use when starting the executable. You'll see all the options in a dropdown menu.

The program '[3400] QuantConnect.ToolBox.vshost.exe: Program Trace' has exited with code 0 (0x0).

Hi Jim, please post more detail error logs back here for more assistance. You can use Visual Studio debugging to step through the code and locate the line causing the error for you.

Jared,

 

I can't seem to generate a more detailed errors.  The code is stopping out on the following block of code which appears to be the very beginning.  I can't seem to get the program to prompt for this information.  Also I'm looking to cycle through every symbol on a particular exchange and grab the information in an automated way, but I can't seem to figure out how this is working.

 

 Console.WriteLine("Usage: GoogleDownloader SYMBOLS RESOLUTION FROMDATE TODATE");
                Console.WriteLine("SYMBOLS = eg SPY,AAPL");
                Console.WriteLine("RESOLUTION = Minute/Hour");
                Console.WriteLine("FROMDATE = yyyymmdd");
                Console.WriteLine("TODATE = yyyymmdd");
                Environment.Exit(1);

Yes, I'm suppose to get a command line to enter that correct?  If so the command line never comes up.

Ok, I found the exe file to initiate this.  Now is it possible to customize this to pull down data in bulk?  For example pull down data on all NASDAQ equities.

0

Ok, I've figured this part out as well.  I found a list of all stocks listed on the NASDAQ from http://eoddata.com/symbols.aspx.  I created a class that turns that list into a comma delimited list of all symbols and I was able to copy and paste that to the command line.  However, I was only able to grab 8 August up to 26 August for some odd reason.  I'm sure there's some limitation documented somewhere that explains the reason.

 

I'll begin testing my strategy and basically see if I can create a stock scanning function and then build from there.  Ultimately I'll need to figure out how to pipe live data into the system so I can act on that in real time.

Cool! Google limits how much minute data you can download. You'll have to set it up to run daily or weekly and capture the data over time. LEAN provides many mechanisms for piping live data into your algorithm (IQFeed) but Google does not offer this service.
