The key to success in the divergent space is your ability to endure disappointment and continuously manage the downside risk. For most long term successful divergent strategies approximately 90% of trades or so are taken simply to keep the head above water…but the anomaly (say 10% of trades) were what led to the overall strong performance metrics of this solution.
Accepting that the market is efficient most of the time does two things to your trading psychology.

Part 3 which is the final installment of this series focuses on fine tuning the portfolio and adding realism to the backtest results. Before we can pluck the courage up to launch into our live trading following our exciting back-test results, now comes the time to remove any bullish euphoria and focus on the reality of live trading.

Part 2 of this installment article focuses on how we go about this blending exercise.
