Hi,
I'm thinking of implementing a simple execution model that splits an order up into smaller pieces and executes one piece every [x] seconds until all piece have been filled.
Is there a way to implement such a delay/sleep that doesn't block the rest of the algo?

I wouldn't advise using delay/sleep.
Why do you not place new orders when one is filled?
In OnData, for example, you place the first order, say buy 100 shares of SPY of a total of 1000.
When an order status changes you are notified at OnOrderEvent, so when that order #1 is filled, you place order #2 (and reduce the total target quantity to 900). When order #2 is filled, you place order #3 (and reduce the total target quantity to 800) and so on.
Alternatively, you can use second-resolution data, create a consolidator for x seconds with an event handler that places the orders.

Hi Alex,
Thanks for the suggestions. I think creating a second-resolution consolidator and bind the order placing function to it is the best approach. I will have to think carefully about how to implement this, as having a second-resolution consolidator would probably add additional computational loads to the system.

If you want to backtest an algorithm that "executes one piece every [x] seconds", there is no way around of having second-resolution data, but you can do it without consolidators.
