Position Sizing code ?

[Synergy <Synergy@xxxxxxxxxxxxxxxx>]

Hello,

I am searching ela or els code or peace of code for calculate position 
sizing after each trade or when in a trade.
I would like to find code with several choices menu options in order to 
choose the position sizing strategy to be apply for testing.
To be integrated in a els system code
No matter what were the options coded, I shall put my own choices.
I just try not to rewrite the major part of a possibly existing working 
code who might do this or nearly similar.
Would someone on the list could help ?

Thank's
Philippe
