Share New Research 
Last September someone wanted to import custom data, and because of security restrictions, QuantConnect does not allow System.IO. I would like to revisit that restriction please.
I am writing an Alorithm for Abhi Goal, a fellow member, and he wants to read in some custom data upon which to base his trades. Call it a custom indicator. QC allows me to get data from an http:// call using WebClient and I would like to process the return data as a Stream. I would like to use StreamReader on the return from the call, but I could live with putting the returned csv data into a String and reading it into a MemoryStream and pass the MemoryStream to my parsing class. Streams are nice because I can grab a line at a time with one call.
I suppose could rewrite the parser to get the lines from the string variable, but that is painful what with having to parse for newlines and substring the result.
Thanks,

AddData("MyIndicator", Resolution.Daily); It doesn't need to be market data, we have examples that import weather data! The defaults for AddData< T > set fill forward=false, so you'll receive data in your OnData(MyIndicator data) only when there's new data on the irregular spacing. When that method fires, place your trade. It should be pretty simple. If you'd like more help, share the csv format. I wouldn't try to lift that data into a QC indicator type or try and merge it with the trade bar information. I think that may be unneeded complexity.Nicholas Stein
AddData("ABHIGOAL", Resolution.Daily); It looks like the only place I can add the Security is in the Initialize function. In the OnData handler tried adding the Security usingAddSecurity(SecurityType.Equity, symbol, Resolution.Daily);but it did not add it. Is there any way to add a Security after Initializing the algo and it is running? When I read the whole list in during Initialize, I was able to loop through and add all the symbols. Of course I do not know the symbols until I get the data. Thanks, NickMichael Handschuh
