Hi,
you can customize position size in the backtesting interface.
same for multiple entry etc, I think there is some sample code i the
help or on the amibroker website under custum backtester.
Regarding margin you have to set the general margin as the lowest
possible and then stock by stock or trade by trade implement your
position sizing strategy.
