• How luck impacts trading strategy results and the impact of selecting the 'best' trading system,
• Why trades in an out of sample dataset are NOT representative of future trades,
• 3 ways to use Monte Carlo Permutation tests in trading strategy development to avoid overfitting, evaluate strategy robustness and assess the quality of your strategy development process,
• The danger of using out of sample trades to compute the probability of drawdowns,
• Entropy and information of indicators and why it's important to strategy development,
• How stationarity really impacts trading strategies and what strategy developers can do about it,
• Using Walk Forward to determine how robust a strategy is in the market,
