Quick question. I just changed the config.json to MovingAverageCrossAlgorithm. It keeps telling me data not found. Do I have to change anything else? I was assuming it would work like the online one where it would just get the sources automatically.
public override void Initialize() { // set up our analysis span SetStartDate(2013, 10, 07); SetEndDate(2013, 10, 11);
// AddData<Yahoo>(Symbol, Resolution.Minute); // request SPY data with minute resolution AddSecurity(SecurityType.Equity, Symbol, Resolution.Minute);
// create a 15 day exponential moving average fast = EMA(Symbol, 15, Resolution.Daily);
// create a 30 day exponential moving average slow = EMA(Symbol, 30, Resolution.Daily);
int ribbonCount = 8; int ribbonInterval = 15; ribbon = Enumerable.Range(0, ribbonCount).Select(x => SMA(Symbol, (x + 1)*ribbonInterval, Resolution.Daily)).ToArray(); }

Hi Frank! Because of data provider restrictions we can't offer a service like that yet -- but we're working on it :) For now you need to purchase your own data and install it in LEAN.

Hi Jared. I have an IQFeed subscription. I see that there is a IQFeedDataQueueHandler. Can you tell me what settings to change in config.json in this section?
I have already changed the iqfeed section. So, what do I change
"backtesting": {
"backtesting-desktop": {

Based on my extremely new understanding, the iqfeed thing is for live data streaming and trading - which while dope is not the backtesting thing you’re looking for.
I have not figured out how to backtest with iqfeed yet.. I think the backtester is mostly intended for processing filesystem data, someone smarter please correct me if I’m wrong

You should just need to change a few config settings.
// iqfeed configuration "iqfeed-username": "", "iqfeed-password": "", "iqfeed-productName": "", "iqfeed-version": "1.0", ... "data-feed-handler": "QuantConnect.ToolBox.IQFeed.IQFeedDataQueueHandler",And that is all -- it assumes IQFeed is already started in the background. You will need to be a registered developer in the IQFeed platform to use that data feed. It will only work for live trading. Backtesting via IQFeed is not supported.
