Show notes: http://optionalpha.com/show92 I've said it for years, position sizing matters in a high probability system. Much more so that you would believe and today's show is the first in a new mini-series we are doing leading up to the launch of our new backtesting software. Inside we'll cover a case study using and iron condor backtest we ran on TLT including the impact on returns that altering the position size had on the portfolio.
