i think this is an application of the flip() function:
//condition must be true to count events
cond1 = flip(Cross(C,MA(C,20)),Cross(MA(C,20),c));/* or
flip(Buy,Sell), for your trading system*/
//the event to count
event = cross(stochd( 7 ),ma(stochd( 7 ),5));// or whatever
//summation
countevents = iif(cond1==true,sum(event,barssince(cond1==true)),0);
I did not try it.
In case you want to use it ony with Buy/Sell events, you should also
have a look at the Exrem() function.
