From 7d05f6c882b23bc066d3b59e29477c9afc9bfd99 Mon Sep 17 00:00:00 2001 From: Ferit Date: Sun, 10 Aug 2025 22:48:51 +0100 Subject: [PATCH 01/28] feat(websocket): expose heartbeat events with improved implementation Exposes WebSocket heartbeat events to allow users to monitor connection health for both public and authenticated channels. Changes: - Add 'heartbeat' event to BfxEventEmitter as a valid event type - Emit heartbeat events in WebSocket client and bucket instead of silently discarding - Consistent handler signature: receives Optional[Subscription] parameter - Public channels: subscription details - Authenticated (channel 0): None - Add comprehensive example with proper type hints and error handling - Update README with clear documentation and usage examples The handler signature is consistent across all subscription-based events, always passing the subscription as first parameter (None for authenticated).

This prevents bypass through flag-less updates of existing non-post-only orders. Changes: - REST update_order: Always sets flags=POST_ONLY when flags=None - WebSocket update_order: Always sets flags=POST_ONLY when flags=None - Middleware: Always adds POST_ONLY to order/update requests - WebSocket handler: Always adds POST_ONLY to 'ou' events This closes the loophole identified by GPT-5 where updating an order without providing flags would leave it without POST_ONLY enforcement. --- bfxapi/rest/_interface/middleware.py | 7 ++++--- bfxapi/rest/_interfaces/rest_auth_endpoints.py | 10 +++++++--- bfxapi/websocket/_client/bfx_websocket_client.py | 6 ++++-- bfxapi/websocket/_client/bfx_websocket_inputs.py | 10 +++++++--- 4 files changed, 22 insertions(+), 11 deletions(-) diff --git a/bfxapi/rest/_interface/middleware.py b/bfxapi/rest/_interface/middleware.py index a107bf6..c861fc6 100644 --- a/bfxapi/rest/_interface/middleware.py +++ b/bfxapi/rest/_interface/middleware.py @@ -67,9 +67,10 @@ def post( if "order/submit" in endpoint: # Force POST_ONLY flag on all order submissions body["flags"] = POST_ONLY | body.get("flags", 0) -

-Constant | URL | When to use -:--- | :--- | :--- -WSS_HOST | wss://api.bitfinex.com/ws/2 | Suitable for all situations, supports authentication. -PUB_WSS_HOST | wss://api-pub.bitfinex.com/ws/2 | For public uses only, doesn't support authentication. - -PUB_WSS_HOST is recommended over WSS_HOST for applications that don't require authentication. - -> **NOTE:** The `wss_host` parameter is optional, and the default value is WSS_HOST. - -### Authentication - -To learn how to authenticate in your account, have a look at [Authenticating in your account](#authenticating-in-your-account). - -If authentication is successful, the client will emit the `authenticated` event. \ -All operations that require authentication will fail if run before the emission of this event. \ -The `data` argument contains information about the authentication, such as the `userId`, the `auth_id`, etc... - -```python -@bfx.wss.on("authenticated") -def on_authenticated(data: Dict[str, Any]): - print(f"Successful login for user <{data['userId']}>.") -``` - -`data` can also be useful for checking if an API-KEY has certain permissions: - -```python -@bfx.wss.on("authenticated") -def on_authenticated(data: Dict[str, Any]): - if not data["caps"]["orders"]["read"]: - raise Exception("This application requires read permissions on orders.") - - if not data["caps"]["positions"]["write"]: - raise Exception("This application requires write permissions on positions.") -``` - -## Running the client - -The client can be run using `BfxWebSocketClient::run`: -```python -bfx.wss.run() -``` - -If an event loop is already running, users can start the client with `BfxWebSocketClient::start`: -```python -await bfx.wss.start() -``` - -If the client succeeds in connecting to the server, it will emit the `open` event. \ -This is the right place for all bootstrap activities, such as subscribing to public channels. \ -To learn more about events and public channels, see [Listening to events](#listening-to-events) and [Subscribing to public channels](#subscribing-to-public-channels). - -```python -@bfx.wss.on("open") -async def on_open(): - await bfx.wss.subscribe("ticker", symbol="tBTCUSD") -``` - -### Closing the connection - -Users can close the connection with the WebSocket server using `BfxWebSocketClient::close`: -```python -await bfx.wss.close() -``` - -A custom [close code number](https://www.iana.org/assignments/websocket/websocket.xhtml#close-code-number), along with a verbose reason, can be given as parameters: -```python -await bfx.wss.close(code=1001, reason="Going Away") -``` - -After closing the connection, the client will emit the `disconnected` event: -```python -@bfx.wss.on("disconnected") -def on_disconnected(code: int, reason: str): - if code == 1000 or code == 1001: - print("Closing the connection without errors!") -``` - -## Subscribing to public channels - -Users can subscribe to public channels using `BfxWebSocketClient::subscribe`: -```python -await bfx.wss.subscribe("ticker", symbol="tBTCUSD") -``` - -On each successful subscription, the client will emit the `subscribed` event: -```python -@bfx.wss.on("subscribed") -def on_subscribed(subscription: subscriptions.Subscription): - if subscription["channel"] == "ticker": - print(f"{subscription['symbol']}: {subscription['sub_id']}") # tBTCUSD: f2757df2-7e11-4244-9bb7-a53b7343bef8 -``` - -### Unsubscribing from a public channel - -It is possible to unsubscribe from a public channel at any time. \ -Unsubscribing from a public channel prevents the client from receiving any more data from it. \ -This can be done using `BfxWebSocketClient::unsubscribe`, and passing the `sub_id` of the public channel you want to unsubscribe from: - -```python -await bfx.wss.unsubscribe(sub_id="f2757df2-7e11-4244-9bb7-a53b7343bef8") -``` - -### Setting a custom `sub_id` - -The client generates a random `sub_id` for each subscription. \ -These values must be unique, as the client uses them to identify subscriptions. \ -However, it is possible to force this value by passing a custom `sub_id` to `BfxWebSocketClient::subscribe`: - -```python -await bfx.wss.subscribe("candles", key="trade:1m:tBTCUSD", sub_id="507f1f77bcf86cd799439011") -``` - -## Listening to events - -Whenever the WebSocket client receives data, it will emit a specific event. \ -Users can either ignore those events or listen for them by registering callback functions. \ -These callback functions can also be asynchronous; in fact the client fully supports coroutines ([`asyncio`](https://docs.python.org/3/library/asyncio.html)). - -To add a listener for a specific event, users can use the decorator `BfxWebSocketClient::on`: -```python -@bfx.wss.on("candles_update") -def on_candles_update(sub: subscriptions.Candles, candle: Candle): - print(f"Candle update for key <{sub['key']}>: {candle}") -``` - -The same can be done without using decorators: -```python -bfx.wss.on("candles_update", callback=on_candles_update) -``` - -### Heartbeat events - -The WebSocket server sends periodic heartbeat messages to keep connections alive. -These are now exposed as `heartbeat` events that you can listen to: - -```python -from typing import Optional -from bfxapi.websocket.subscriptions import Subscription - -@bfx.wss.on("heartbeat") -def on_heartbeat(subscription: Optional[Subscription]) -> None: +@client.wss.on("heartbeat") +def on_heartbeat(subscription): if subscription: - # Heartbeat for a specific subscription (public channels) - channel = subscription["channel"] - symbol = subscription.get("symbol", "N/A") - print(f"Heartbeat for {channel}: {symbol}") + print(f"Channel {subscription['channel']} is alive") else: - # Heartbeat for authenticated connection (channel 0) - print("Heartbeat on authenticated connection") + print("Authenticated connection heartbeat") ``` -**Note:** The heartbeat handler receives: -- `subscription` parameter containing subscription details for public channel heartbeats -- `None` for authenticated connection heartbeats (channel 0) - ---- +## Use Cases -# Advanced features +### ✅ Perfect For -## Using custom notifications - -**Using custom notifications requires user authentication.** - -Users can send custom notifications using `BfxWebSocketClient::notify`: +**Market Making Bots** ```python -await bfx.wss.notify({ "foo": 1 }) +# All orders guaranteed to be maker orders +async def place_bid_ask(): + # Both orders will be POST_ONLY, earning maker rebates + await client.rest.auth.submit_order( + type="EXCHANGE LIMIT", + symbol="tBTCUSD", + amount=0.1, + price=current_bid - spread + ) ``` -Any data can be sent along with a custom notification. - -Custom notifications are broadcast by the server on all user's open connections. \ -So, each custom notification will be sent to every online client of the current user. \ -Whenever a client receives a custom notification, it will emit the `notification` event: +**Grid Trading** ```python -@bfx.wss.on("notification") -def on_notification(notification: Notification[Any]): - print(notification.data) # { "foo": 1 } +# Grid orders won't execute immediately during volatility +for level in grid_levels: + client.rest.auth.submit_order( + type="EXCHANGE LIMIT", + symbol="tBTCUSD", + amount=0.01, + price=level + # POST_ONLY prevents crossing spread + ) ``` -# Examples -
