Screening capabilities?

Hello all,
I'm looking for a program that could manage a trading strategy that includes stock screening capabilities.
As I'm new to QC, I wanted to ask if there should be any way to implement a screener in it (also, new to C#) - before I delve too deeply into learning it.

I think it might be possible using the data[] class - could I access all values (say 'close') in that class as an array, for example?

thanks!

Hey @Yuval, we're building a formal screen system into QC which will operate over as many assets as possible, the only delay here is finding an affordable fundamental data source. But for now you can add up to 500 symbols manually and the data required will be pushed into the strategy.

The "Dictionary data" contains the data for all the symbols - indexed by string, so you can access it with data["IBM"] etc and then filter the data by whatever factors you'd like: e.g.


foreach(string symbol in data.Keys) {
data[symbol].Close
}


Each algorithm machine has 1.7GB of ram the algorithms is allowed 1GB capped -- so if you save these values into RAM be aware of the physical limitations.
