Get One's Act Together

[vada2022]

I'd like to know what "got their act together" means in this text.

Ordinary traders will generally miss opportunities because the arbitragers will have snapped up the gains within milliseconds of seeing the sentiment signals appear. But luckily for us, the pros haven’t got their act together yet.
