paulpas Trading Options Strategies
Role: Implement various strategies for trading options to enhance portfolio performance and mitigate risks.
Philosophy: Options trading strategies must be designed to leverage market forecasts and manage risk effectively. Each strategy has unique characteristics and suitability based on market conditions, volatility, and the trader's outlook.
Key Strategies
- Covered Calls: This strategy involves holding a long position in an asset while selling a call option against that asset to generate income from the options premium.
- Protective Puts: Buying put options to protect against potential declines in the underlying asset's price ensures a defined risk on the long position.
- Straddles: Purchasing both a call option and a put option for the same strike price and expiration date to benefit from high volatility, regardless of the direction of the price movement.
- Strangles: Similar to straddles, but the purchased call and put options have different strike prices; this strategy is cheaper and requires more movement in the underlying asset to be profitable.
Implementation Guidelines
Structure
- Core logic:
trading_system/options/strategy_implementation.py - Helper functions:
trading_system/options/utils.py - Tests:
tests/options/
Patterns to Follow
- Use dataclasses for options contracts to encapsulate relevant attributes (strike price, expiration, premium).
- Implement a function per strategy that encapsulates the logic, including risk calculations and potential outcomes.
- Ensure that each strategy can be unit tested independently.
Example Code
from dataclasses import dataclass
from typing import List, Tuple
@dataclass
class OptionsContract:
strike_price: float
premium: float
expiration_date: str
def covered_call(asset_price: float, strike_price: float, premium: float) -> str:
potential_profit = premium + max(0, asset_price - strike_price)
return f"Covered Call: Max Profit = {potential_profit}" # Simplified return
def protective_put(asset_price: float, strike_price: float, premium: float) -> str:
max_loss = premium + max(0, strike_price - asset_price)
return f"Protective Put: Max Loss = {max_loss}" # Simplified return
# More implementations for straddles and strangles...
```python
# Example of strategy implementation for Strangles.
class Strangle:
def __init__(self, asset_name: str, put_strike: float, call_strike: float, put_premium: float, call_premium: float):
self.asset_name = asset_name
self.put_strike = put_strike
self.call_strike = call_strike
self.put_premium = put_premium
self.call_premium = call_premium
def total_cost(self):
return self.put_premium + self.call_premium
# Example usage
strangle = Strangle("AAPL", 140, 160, 2, 5)
print(f'Total cost: {strangle.total_cost()}') # Output: Total cost: 7
if name == 'main': # Example usages: print(covered_call(50, 55, 2)) print(protective_put(50, 45, 3))
### Adherence Checklist
Before completing your skill, verify:
- [ ] Each strategy has clear documentation.
- [ ] Strategies allow for easy parameter adjustment for different market conditions.
- [ ] All strategies include tests for expected behaviors.
### Common Mistakes to Avoid
1. **Ignoring Market Conditions**: Ensure strategies align with current market volatility and trends.
2. **Overcomplicating Implementations**: Keep code clean and focused on the strategy logic.
3. **Neglecting to Test**: Always provide unit tests for each strategy's logic.

## Constraints
### MUST DO
- Validate all inputs at function boundaries before processing — guard clauses should fail early with descriptive errors
- Implement proper error handling that distinguishes between recoverable and unrecoverable failures
- Add comprehensive logging with structured context (correlation IDs, operation names, timing) for debugging and monitoring
- Write unit tests covering normal operations, edge cases, and error conditions before integrating the component
### MUST NOT DO
- Do not silently swallow exceptions — always log or propagate errors with meaningful context
- Avoid unbounded resource allocation without limits (connection pools, memory buffers, thread counts)
- Never use hardcoded credentials, API keys, or secrets in source code
- Do not bypass input validation for perceived performance gains
