Not really sure why I have to use a consolidator to access minute data? I'm a day trader. ALL of my strategies involve intraday trading. But okay....
I'm looking at your "How to use Consolidators" algorithm in QU. Trying to convince myself of exactly what data this is returning. What line of code would I need to add to see the value of SPY, minute by minute?
//Traditional 1 minute events here:
public void OnData(TradeBars data)
{
Debug("The value of SPY is " + ???????????);
Order("SPY", 100);
}

Or even better
Debug("The value of SPY is " + ????? + " and the date and time are " + ??????);

If you click "Create New Project" then select C# the "Basic Template C#" template that is loaded does exactly what you are asking for. Note: That for backtesting it is against the terms of service to log price data. However for live your exact debug statement would be
Debug("The value of SPY on " +data["SPY"].Close.ToString("#.##")+ " and the date and time are " + Time.ToShortDateString());

Its also advisable to check the data array first to make sure it contains the key you are looking for. so...
if (data.ContainsKey("SPY"))
{
// Do stuff
}

Most excellent! Thank you! I was missing the ToString("#.##") part.
Have a great w/e!

Sure thing. Also about the consolidators: Equity data is pre-consolidated for you at resolutions of Tick, Sec, Min, Hour, Daily. See "Data Library" at https://www.quantconnect.com/docs
So when you use AddSecurity you can pass it the resolution you would like. Consolidators are handy when you want other resolutions (say 10 minutes) etc
As an example:
AddSecurity(SecurityType.Equity, "SPY", Resolution.Minute);
AddSecurity(SecurityType.Equity, "SPY", Resolution.Hour);
AddSecurity(SecurityType.Equity, "SPY", Resolution.Tick); // Note this comes in its own OnData event .See https://www.quantconnect.com/docs#Handling-Data
