Accumulation and Order Concurrency In Normal Strategy

[Jacob]

according to the docs - Strategy with Signals

This would lead to a continuous generation of orders that would produce 2 situations:

• Accumulation: even if already in the market, the signals would produce new orders which would increase the possition in the market

• Concurrency: new orders would be generated without waiting for the execution of other orders

While dealing with this behavior is applied to signals, I was wondering how can it be applied to a normal strategy?
not sure how it works in Signals, but what type of logic can one write to accomplish this idea on a strategy level?

Most basis examples include a sentinel in the code (an attribute in the strategy). If the attribute is not None you have a pending order. If the order is completed or cancelled, you set it to None
