Enjoying trying out the tool. Very eye opening to backtest different systems. What are your recommended settings for volatility? Adjusting volatility can make or break profitability significantly. If I use the "calculate" button, which option's volatility should I use? Here's an example trade: http://option-risk.appspot.com/Opti...Q_TefExPXcJ_z9afpWalI8444zsoCaZgDCQzYbflpTw== The volatility for the 4 different positions are different. And trying each volatility number yields different results (profitable to unprofitable). Would appreciate your advice, thanks!
