Murray,

I found the following:

"Optimal f with volatility. Murray Ruggiero proposed to adapt the position size calculated using the optimal f to the current market volatility.. This is founded on the hypothesis that when the market volatility is low, the chance of having a large loss is larger than when the volatility is high. We normalize the volatility from 1 to 0, where 0 is maximal volatility, and 1 – minimal:

Volatility_norm = (Max_Volatility – Current_Volatility / (Max_Volatility – Min_Volatility)

Then

Num_Lots = f_opt * Volatility_norm * Capital /

( -Max_Loss_Estimate)

Here the, f_opt is calculated also using the maximal loss evaluation."

Was wondering if you still believed in this methodology.  I'm also curious, naturally, how you'd set this up and calculate it in TS.  Any thoughts appreciated.

I actually found this article a few weeks ago and have not had a chance to code it up in TradersStudio yet. When I do , I will post the results.
