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. We do this to dampen our expectations and ensure our risk weightings are correctly applied for live conditions. This is where the brutal reality of the frictional costs of trading need to take center stage….as we inevitably incur additional costs to that anticipated from our back-tests attributed to the realities of live trading.
