Here is an example to calculate the difference between the last two Buys, replace Buy with your event. The plotting is just to show it works.

// My secret system to give some signals (Do NOT trade!)
SetOption("Allowsamebarexit",False);
Buy = BuyPrice = Cover = CoverPrice = L;
Sell = Short = SellPrice = ShortPrice = H;
Equity(1);
// Difference between the last two Buy events
B1 = ValueWhen( Buy, BuyPrice, 1 );
B2 = ValueWhen( Buy, BuyPrice, 2 );
B = B1 - B2;
Plot(C,"Close",colorBlack,styleBar);
PlotShapes( IIf(Buy, shapeSmallCircle, shapeNone),colorGreen, 0, BuyPrice, 0 );
PlotShapes( IIf( Sell, shapeSmallCircle, shapeNone),colorRed, 0 ,SellPrice, 0 );
Plot(SelectedValue(B1),"B1",colorYellow);
Plot(SelectedValue(B2),"B1",colorBlue);
Title = "Difference between the last two buys: "+NumToStr(B,1.2);
