Risk averse fractional trading using the current drawdown
  In this paper the fractional trading ansatz of money management is reconsidered with special attention to chance and risk parts in the goal function of the related optimization problem. By changing the goal function with due regards to other risk measures like current drawdowns, the optimal fraction solutions reflect the needs of risk averse investors better than the original optimal f solution of Ralph Vince.   Keywords: fractional trading, optimal f, current drawdown, terminal wealth relative, risk aversion
