If by aggregate result you mean that you want to see what would happen to total equity, win/loss ratios, etc. when taking all signals together, then I think that you have answered your own question.
Given that gains and losses in the other stocks have a direct impact on what is available to apply to the current signal, I believe that you must employ some form of portfolio allocation. Taking it to the extreme, you need to know that you are bankrupt before considering the next signal. Similarly, even at $1 position size, if you generate more signals than you have cash, something has to give. If you just want to see how each symbol individually would perform, you can select "Individual Backtest" from the drop list of the Backtest button in the AA window.
