%description
A module to collect ohlc candles from Kraken using WebSockets that is asyncio friendly! Looking for automated trading tools? [Botcrypto](https://botcrypto.io) may interest you.
## Key features
- Subscribe to kraken data using a single WebSocket.
- Trigger a callback that is coroutine on each new closed candles from kraken.
- Easy subscribe/unsubscribe to datasets, i.e. [(pair, Unit Time)] ex: [('XBT/EUR', 1)].
- Callback is regularly triggered at each end of the UT intervals, whatever is the number of data received by kraken.
## Getting started
#### Install
`pip install aio-kraken-ws`
#### Usage
```python
# check tests/learning/log_to_file.py for a complete example
async def callback(pair, interval, timestamp, o, h, l, c, v):
    """ A coroutine handling new candles.
    """
    with open("candles.txt", "a+") as file:
        file.write(f"[{pair}:{interval}]({timestamp},{o},{h},{l},{c},{v})\n")
kraken_ws = await KrakenWs.create(callback)
# subscribe to some datasets
kraken_ws.subscribe([("XBT/EUR", 1), ("ETH/EUR", 5)])
```
The `callback` function is called for each dataset at the end of each dataset's unit time interval.
E.g. if subscription start at 4h42.05 to the dataset `("XBT/EUR", 1)`, then callback is triggered at 4h43.00, at 4h44.00, at 4h45.00, etc... For `("XBT/EUR", 60)`, it would be at 5h00.00, at 6h00.00, etc... It's possible to get at most 10ms delay between the exact UT interval ending and the actual datetime of the call.
If **no** new data were received from Kraken during an interval, the callback is triggered with the latest known close price and v=0, as it's described in the following example.
E.g.
```python
kraken_ws.subscribe([("XBT/EUR", 1)])
# time.time() = 120
await callback("XBT/EUR", 1, 60, 42.0, 57.0, 19.0, 24.0, 150.0)
# time.time() = 180
await callback("XBT/EUR", 1, 120, 19.0, 24.0, 8.0, 10.0, 13.0)
# time.time() = 240 : no data received in 60s, i.e. no activity
await callback("XBT/EUR", 1, 180, 10.0, 10.0, 10.0, 10.0, 0.0)
```
### Error management
- An exception raised by the `callback` will be logged and it wont stop the streams
- If kraken send an error message, an `ERROR` log is emitted with the kraken payload
- If kraken send 'Subscription ohlc interval not supported', the related dataset is automatically unsubscribed
#### Warning
The `callback` should takes less than a minute to process. If the `callback` takes more than a minutes, a *warning* is emitted and you may lose market data.
Kraken WebSocket server manage **20 subscriptions maximum** per connection. Above 20 subscriptions, you may not receive all desired data.
**Hopfully, aio-kraken-ws manage this limitation for you!** A new websocket connection is open every 20 subscriptions.
Moreover, after 24h a subscriptions seem to expire and no more market data is receive. To ensure we do not lose the stream of market data, **aio-kraken-ws** automatically reconnect and re-subscribe to the datasets every 5 minutes.
## Tests
You can find a working example of KrakenWs in `tests/learning/log_to_file.py`.
### Run tests locally
Clone the repo and install requirements
```sh
pip install -e .[test]
```
Run the suite tests
```sh
# unit tests - no call to kraken - fast
pytest --cov=aio_kraken_ws --cov-report= -v tests/unit
# integration tests - actual kraken subscription - slow
pytest --cov=aio_kraken_ws --cov-append -v -n 8 tests/integration
```
