Ticker channel differences

Advanced Trade API
1

Both Pro and Advanced Trade has ticker channel with identical description:

The ticker channel provides real-time price updates every time a match happens. It batches updates in case of cascading matches, greatly reducing bandwidth requirements.

It does not work like Pro channel. Same with ticker_batch channel! Why are these channels different from Pro while using same name and description?

There is market_trades channel, but this channels sends updates only every 250 ms. As API user I want to receive updates as soon as possible…

Just continue using the pro feed until they provide an acceptable substitute.

Whole Advanced Trade API is worse! Other channels require authentication and I am sure sooner rather than later Pro API keys will stop working…
