I would not overcomplicate the interface with too many options (config or class instance feels overkill).

Also. If possible, we should work with interfaces and not actual class implementation.

Great there's no TS casting!

Nice also we pass the orderbook API. I think is better than depend on the config.

On my last review, i was hinting that ideally we would depend on simpler interfaces instead of a full instance of a class.

This is a nit, but as you asked for feedback on this regard, I recommend to not depending on the poll method on the full Orderbook API (and less on an instance of an implementation).

You could depend on a simple interface: i.e. getOrder
Or even better, you can close even further the interface by passing a existsOrder(string: orderId): boolean

will this affect to anything in learn.cow.fi?

[mfw78]

There is no use of polling yet in any tutorials there.
