Ton,
By default, AddToComposite is only evaluated during a scan. If you want to have it executed during an exploration, backtest, portfolio backtest or within an indicator, you must pass the appropriate flag value.
If you want your composite to reflect ~~~Equity, then the example I gave earlier is the way to do it (i.e. calculate your composite at the same time that AmiBroker calculates ~~~Equity during portfolio backtest).
