Usage

Here are some sample usages:

import yaml

from pyschwab.auth import Authorizer
from pyschwab.trading import TradingApi
from pyschwab.types import Symbol
from pyschwab.market import MarketApi

# Load configuration
with open("config/pyschwab.yaml", 'r') as file:
    app_config = yaml.safe_load(file)

# Authorization
# On the first run, this will open a browser for authorization.
# Follow the instructions. Subsequent runs will auto-refresh the access token.
# When refresh token expires, it will open browser for authorization again.
authorizer = Authorizer(app_config['auth'])

access_token = authorizer.get_access_token()
print(access_token)

# Example usage of trading APIs
trading_api = TradingApi(access_token, app_config['trading'])
trading_data = trading_api.fetch_trading_data()
# List positions
for position in trading_data.positions:
    print("position:", position)

# List transactions 
for transaction in trading_api.get_transactions():
    print("transaction:", transaction)

# Buy/Sell equity
trading_api.buy_equity("TSLA", quantity=10, price=100)
trading_api.sell_equity("TSLA", quantity=10, price=200)

# Buy/Sell option
symbol = Symbol("RDDT", expiration="260116", call_put=True, strike=50.00)
trading_api.buy_single_option(symbol, quantity=1, price=10)
# Or: trading_api.buy_option("RDDT  260116C00050000", quantity=1, price=10)

trading_api.sell_single_option(symbol, quantity=1, price=30)

# Buy Call Spread
trading_api.trade_spread("TSLA", 0.9,  "2024-05-31", buy_sell=True, call_put=True, strikes=[177.5, 180], quantity=1)

# List orders
for order in trading_api.get_orders():
    print("order:", order)

# Example usage of market APIs
market_api = MarketApi(access_token, app_config['market'])

# Get quotes
symbols = ['TSLA', 'NVDA']
quotes = market_api.get_quotes(symbols)
for symbol in symbols:
    print("quote for ", symbol, ":", quotes[symbol])

# Get option chains
option_chain = market_api.get_option_chains('TSLA')
print(option_chain)

# Get price history 
history = market_api.get_price_history('TSLA')
print(history)
