## Installation
Install ssc2ce with:
```bash
$ pip install ssc2ce
```

You can run some examples with
## Bitfinex
### Description
API description look at [Websocket API v2](https://docs.bitfinex.com/v2/docs/ws-general)
### Basic example
```python
import asyncio

from ssc2ce import Bitfinex

conn = Bitfinex()

def handle_subscription(data, connector: Bitfinex):
print(data, f"received:{connector.receipt_time}")

async def subscribe():
await conn.subscribe({
"channel": "ticker",
"symbol": "tBTCUSD"
}, handler=handle_subscription)

conn.on_connect_ws = subscribe

loop = asyncio.get_event_loop()

try:
loop.run_until_complete(conn.run_receiver())
except KeyboardInterrupt:
print("Application closed by KeyboardInterrupt.")

```

## Deribit
### Description

API description look at [Deribit API v2 websocket](https://docs.deribit.com/v2/?python#json-rpc)

### Basic example
```python
import asyncio
from ssc2ce import Deribit

conn = Deribit()

async def subscribe():
await conn.send_public(request={
"method": "public/subscribe",
"params": {
"channels": ["deribit_price_index.btc_usd"]
}
})

def handle_subscription(data):
method = data.get("method")
if method and method == "subscription":
if data["params"]["channel"].startswith("deribit_price_index"):
index_name = data["params"]["data"]["index_name"]
price = data["params"]["data"]["price"]
print(f" Deribit Price Index {index_name.upper()}: {price}")

conn.on_connect_ws = subscribe
conn.method_routes += [("subscription", handle_subscription)]

loop = asyncio.get_event_loop()

try:
loop.run_until_complete(conn.run_receiver())
except KeyboardInterrupt:
print("Application closed by KeyboardInterrupt.")

```
