Algo data frequency...

Hello,
Two-part question:

Is it possible to create entry logic that is based on end-of-day/closing stock data?
Then once the entry is triggered on closing data, I trade it intraday, say on 15 minute bars?

Can you provide an example?

Thanks so much.
Preston

Sure, take a look at schedule_function to arrange a time when to enter/exit positions: https://www.quantopian.com/help#ide-schedulefunction

Hi Preston,

I just wrote up this simple example of what I think you are trying to do. This code prints the current price of each stock in our universe (just AAPL and MSFT for this example) every 15 minutes, every day, as long as their close price from the previous day was greater than $100.

Let me know if this helps!

Hello Jamie!
Thanks for creating this example. I was thinking about triggering the system on daily data. For instance say AAPL last close crossed above one standard deviation above its 50 day SMA. I would like to short on the open. Also, say I have a generic profit rule of 2%, and stop loss of 5% based off the fill. After the fill, I would like to trade on 15 min bars, to see if I reach the profit or stop loss targets.

So basically triggered on daily data, but traded on 15min bars.

Does that make sense? Let me know if not, I'll try and clarify.

Thanks again!

Hi Adam,

Were you able to implement your idea by using my example as a reference? I'm not really sure what you're asking me! If you're asking my opinion on the strategy, I would recommend first running a few backtests to see how your algorithm performs on historical data, and then post you backtest here.
