Thanks for a quick response, Pipcop.
I'm not sure whether we're talking about quite the same thing though. I'm not talking about 2
currency 
pairs in a shadow
hedge 
configuration. I'm talking about trading with 3 or 4 pairs, each in a separate instance of GT-Shadow with different magic numbers.
It would be nice to be able to use the UseEquity option so that if one or two of the pairs were experiencing large drawdowns, the lot sizes on new trades for all the pairs could be adjusted accordingly minimising the chance of an account blowout.
