zb has since been delisted

bybit has since been updated to v5

ftx has been delisted

``` ccxt.base.errors.ExchangeNotAvailable: gateio {"label":"INTERNAL","detail":"thread-sync"} ``` this error seems to be a gateway error specific to gateio - not much we can do about that on the client side

#15796

#15944

closing because we have moved the entire file to the v3 api

I think that the leak is coming from the orderbooks... will have to rewrite it probably

Looks like the heap is getting bigger - slowly. (after about 10 mins)...

can confirm
