If I open the one of the other xml's (lastSettings.xml). This one has the correct MM selected.
I'm not sure which xml sqx uses as when it reads/rebacktests/exports the correct MM is found so must not be from strategy_Portfolio.xml.
This bug has been tested on two separate users/machines both running v135. So it might just be a v135 problem.
Status changed from New to Refused
Please ignore what is set in strategy file strategy_Portfolio.xml. MM fixedSize=1 is there because of compatibility with old system.
