Release 0.8.5¶
2022-06-06
Gateways¶
OKX¶
TopOfBook
is now sourced from the bbo-tbt
channel.
Warning
It is no longer possible to use ws_books_depth=1
!!!
API Changes¶
roq::cache::Manager
no longer a template class.
The only downstream change should be the removal of template arguments.
Reference Data¶
Gateways can now (optionally) capture all reference data from the exchange, regardless what
symbols
regex-matching has been chosen.
A new flag --cache_all_reference_data
has been added to support this.
“Idle” Streams¶
Sometimes it can happen that a connection remains open yet no “important” data seems to arrive.
A new general flag has been introduced which may be used to force disconnect of a stream after
a timeout has expired: --net_disconnect_on_idle_timeout
.
Warning
This flag is not always used. The reason is that not all messages of a communication protocol can be considered “important”. For example, ping/pong messages should not be considered “important”. Streams dedicated to order entry / drop copy are other examples of “tricky” connections due to very little activity expected on these connections.
Note
This change was specifically implemented to support the Huobi gateway (#227).
Tools¶
A new query tool has been added: roq-query. This tool is useful to quickly create pivot tables like this
$ roq-query ftx.roq --type count --event_type top_of_book --period 5m --stream_id 6 --symbols "BTC.*,ETH.*"
receive_time_utc,"BTC-0624","BTC-0930","BTC-PERP","BTC/USD","BTC/USDT","ETH-0624","ETH-0930","ETH-PERP","ETH/USD","ETH/USDT"
