[EquisMetaStock Group] Re: HELP - customizing Historical Volatility

Hi MG Ferreira:
  It does not matter whether the structure is MSFL or not. Any 
suggestion for the formula will be great.  

On the other hands, I am facing with the issue of normalizing 
volatility, such as historical volatility, bollinger band, ADX, 
Average true range ..., since there is no clear relationship between 
volatility and the close price, so I cannot set the weight by 
comparing the closing price with the previous one. Do you have any 
suggestion on how to set the weights for the volatility?
Thank you very much
Eric :>
