The tool you need for storing past values is the RollingWindow, another alternative is using History
To get today’s open you can use a Schelude the first minute before the market opens and store in a field.
Here is an example:
public class BasicTemplateDailyAlgorithm : QCAlgorithm
{
private RollingWindow<TradeBar> _dailyBars = new RollingWindow<TradeBar>(3);
private TradeBar _todayFirstMinuteBar;
public override void Initialize()
{
SetStartDate(2013, 10, 07); //Set Start Date
SetEndDate(2013, 10, 18); //Set End Date
SetCash(100000); //Set Strategy Cash
AddEquity("SPY", Resolution.Daily);
Schedule.On(DateRules.EveryDay(), TimeRules.AfterMarketOpen("SPY", 1), () =>
{
_todayFirstMinuteBar = History<TradeBar>("SPY", TimeSpan.FromMinutes(5), Resolution.Minute).Last();
});
}
public override void OnData(Slice slice)
{
_dailyBars.Add(slice.Bars["SPY"]);
if (_dailyBars.IsReady)
{
var todaysOpen = _todayFirstMinuteBar.Open;
// Implement your logic here.
}
}
}
Thanks JayJayD,
I have used the code you provided, but it gives data till previous date only. I will set the start date to "2017-10-23" and end date to "2017-10-26". The code should provide minute data starting from 2017-10-23 09:30:00 to 2017-10-26 03:23:00, if the datetime.now is 2017-10-26 03:24:00.
For minute-data of the past 2 days, please use:
Start New Discussion 
Back
Reward Discussion 
3
var lastTwoDayData = History("SPY", TimeSpan.FromDays(2), Resolution.Minute);Please note that it fetches the last two days, not the last two trading days, so you need to addapt the code to handle Mondays, Tuesdays and days after holidays.
