Evaluating Risk Management
Since trading is inherently risky, comprehensive risk management is crucial:
- Constrain Position Sizes – Limit maximum size for open positions and total portfolio based on volatility.
- Use Stop Losses – Automatically exit losing positions after predefined thresholds to control downside.
- Balance Portfolios – Maintain diverse uncorrelated instruments and strategies to mitigate risk.
- Limit Leverage – Establish sensible limits for borrowed capital to avoid margin calls.
- Follow Regulatory Requirements – Ensure capital, collateral, and other regulatory needs are satisfied.
- Conduct Stress Testing – Quantify potential losses under extreme hypothetical market conditions.
- Monitor Execution Slippage – Measure deviation between expected fills and actual execution prices.
Without prudent risk analysis and mitigation, even the best AI models can lead to disastrous losses.
Backtesting and Optimizing Strategies
No trading algorithm or model should be deployed live until rigorously backtested:
- Use Historical Data – Train models and simulations on past data to estimate future performance.
- Optimize Parameters – Tweak inputs like technical indicators and profit taking thresholds to maximize returns within risk limits.
- Verify Statistical Significance – Ensure simulated performance metrics like Sharpe ratio exceed thresholds demonstrated over sufficiently long time periods.
- Apply Robust Validation – Validate models using techniques like walk-forward analysis, k-fold cross-validation.
- Evaluate Across Market Conditions – Test performance in both historical bear and bull markets.
- Check for Overfitting – Detect and correct overfit models that show fantastic results on past data but fail out-of-sample.
- Assess Fees Impact – Factor in realistic trade commissions, exchange fees, and other transaction costs.
Without rigorous backtesting, strategies likely won’t hold up in the brutally competitive live markets.
Deploying and Monitoring Bots
Once algorithms are thoroughly vetted, it’s time to deploy them live:
- Start Small – Initially trade small position sizes live to confirm models work as expected.
- Monitor Markets Closely – Watch for major new developments that could require halting algorithms.
- Check Outputs – Verify automated trades match expected strategy behavior.
- Duplicate Systems – Maintain identical mirrored trading environments across multiple cloud regions to enable failover.
