Hey Conrad,
All trading methods over all asset classes, managed by managers who know what they are doing.
That was roughly the synopsis, as i understood it.
About the average share cost, it is indeed trivial, but up till now i calculated it for each transaction via a calculation that took in account what i had, how much i bought or sold and calculated the new avg price.
This new calculation is much simpler and is equivalent, without any difficult calculations especially when you do some nonstandard stuff to your machine.(like taking part from the machine and combine it with another machine)
Kind Regards,K
