how to load historical data in strategy?

Hello toughgetsgoing,

That I know of, there are no sources of unlimited free tick or minute data from the market.

Hi Chelsea,

I am able to backtest my strategy properly now. I have some technical question.

On start of every new day, I do an asynchronous bars request for past 100 days (daily data). By the time I receive the data, all the intraday updates (OnBarUpdate) are already processed.

Is it possible to request the data synchronously instead? (without using C# constructs like WaitHandles). On start of every new day: I would like to request past 100 days daily data, process the data and then start processing OnBarUpdate updates.

Hello toughgetsgoing,

I am not aware of any safe ways to perform this sequentially.

I think a thread sleep would be necessary but this not supported by (and is always advised against by) NinjaTrader Support to do.

Thanks Chelsea. I am using Thread.Sleep function as of now and the functionality in backtest is working as i expect. I don't expect this to cause any issue in live trading as this will be called only once at the start of the strategy.
