When you perform a portfolio backtest, AmiBroker automatically loops
over each symbol in the watchlist, giving your AFL a chance to
generate buy/sell signals for each symbol. The Buy and Sell signals
always refer to the current symbol, Name(). You could place both
symbols in the same watchlist, or perform two separate backtests on
different watchlists.

Im running it on the first watchlist and then using the
setforeign(opposite ); function. But Im having a problem. There are
variables I declared early in the code. Then I say setforeign(opposite
); Then put in buy conditions based on those variables but I get no
buys or sells in this foreign ticker. Only buys and sells in the first
watchlist. How come?
