Market order (taker) delay

[tuxitor]

Are there any reasons for this delay when using the --order_type=taker unless taking orderbook into consideration? As far as I can see it is no checking of the orderbook taking place.

I was wondering the same. Is there any specific reason?

At a guess, this is likely due to the same problems I discuss over in #868. In short, there are a number of bugs or otherwise reasonable-to-expect errors which can cause an order to fail to be opened within a single period, but in these cases the signal is being acknowledged via the acted_on_trend flag, anyway.
