Treat each indicator buy signal as its own trade

[TonyR]

Hi I'm trying to find the 1 and 3-year returns in the 'SPY' following an event--in this case, my custom indicator crossing above a reading of 30. The issue is I'm not sure how to break out individual trades that happen inside the time frame. For example, the trades shown below has a trade on 8/16/2002 and then another one on 10/18/2002. So I'd like to see the 1-year and 3-year returns for both the signal on 8/16/2002 and on 10/18/2002 trade. Here's an example of what I mean:

Ideally, I'd like to get the rate of return over the time frames mentioned. Please help!

This is the code I have so far:

bbi=Foreign("~BBI","C");
Buysignal=Cross(bbi,30);
oneyearlater=Ref(buysignal,-252);
threeyearslater=Ref(Buysignal,-756);
fiveyearslater=Ref(buysignal,-1260);
Filter=buysignal;
AddColumn(buysignal,"Buy");
AddColumn(ValueWhen(BUYSIGNAL,C),"ValueWhen");
AddColumn(ValueWhen(oneyearlater,C),"OneYearLater");
AddColumn(ValueWhen(threeyearslater,C),"ThreeYearsLater");
AddColumn(ValueWhen(fiveyearslater,C),"FiveYearsLater");
//AddColumn( ValueWhen(oneyearlater,DateTime()), "Date / Time", formatDateTime ); 
Buy=buysignal;
Sell=Ref(buysignal,-252);

I managed to solve this, although I would love some constructive criticism. I ended up reading the user manual h/t Tomasz and I read about setbacktestmode( backtestRegularRaw2Multi). That allowed me to break out each individual trade. Then I was reading other threads and found @fxshrat 's solution to another issue that said just use the applystop function and set the number of bars to however many you need.
So h/t to both of you, and everyone on this forum that is very helpful to those of us that aren't as powerful programmers.
Thanks again,

The "Multi" mode is exactly for that purpose and yes reading manual helps
