$ conda install \

  roq-ftx

$ cp $CONDA_PREFIX/share/roq-ftx/config.toml $CONFIG_FILE_PATH

# Then modify $CONFIG_FILE_PATH to match your specific configuration

$ roq-ftx \
      --name "ftx" \
      --config_file "$CONFIG_FILE_PATH" \
      --client_listen_address "$UNIX_SOCKET_PATH" \
      --metrics_listen_address "$TCP_LISTEN_PORT" \

Config#

Flags#

$ roq-ftx --help

--rest_download_freq

Download frequency for positions and funds, e.g. 30s

--rest_funding_rates_poll_freq

Download frequency for funding rates, e.g. 5s

--ws_order_book_checksum_every

Number of updates between validating order-book checksum (0 means never validate).

--cancel_on_disconnect

The Logon FIX message can be used to instruct the exchange to automatically cancel all orders if a disconnect has been detected.

--fix_oms_strict_validation

Can be used to enable more strict validation of order parameters, e.g. not allowing market orders if using FIX for order entry. Default is to send all order parameters to the exchange for validation. However, this could potentially have an adverse effect on the rate-limiter.

Streams#

Type

Comments

FIX

Primary purpose

  • support order management

Each connection

  • supports a single account

Type

Comments

REST

Primary purpose

  • live account updates, including orders and fills

Each connection

  • supports a single account

The master account is used to

  • discover the full list of symbols (by downloading exchange info)

  • request depth snapshots

Type

Comments

WebSocket

Primary purpose

  • live market data

  • reference data and markets (from the markets channel)

Each connection

  • supports a slice of the symbols

The first stream is used to

  • subscribe the markets channel

Constraints#

  • The gateway requires a master account definition to be functional. This is currently needed by the market data connection.

  • Rate-limit usage is not communicated by the exchange

  • Order book

    • Max depth is 100

  • Order download doesn’t reveal how many execution reports should arrive

    • The solution is to make the connection ready some time after the last downloaded execution report has been received

Comments#

  • Order book

    • Top-100 checksum is not being verified for latency reasons

    • Instructions to clear levels appear outside top 100

  • Order Management

    • TimeInForce is automatically converted to IOC if order size too small. (More details here.)

    • Have seen FIX execution reports with pending-cancel arrive after cancel. For this reason, all pending-cancel are dropped.

    • REST/WS is unreliable at this point. Ordering is a real issue. Also, the automatic conversion to IOC is causing issues because the WS orders channel reports the order to be closed oftentimes followed by a REST response with order details indicating the order is working (new).
