formula for an indicator to display no. of whipsaws

[Adam Hardy <adam.ts@xxxxxxxxxxxxxxxxxx>]

I'm currently looking at break-out systems where there is a huge propensity for 
whipsaws, by which in my little world I mean the number of times my break-out 
stops above and below the market both get hit on the same day.
To make it obvious on the screen, I want to have an indicator showing the 
cumulative number of days with whipsaws.
I got so far but am stuck since TS won't let me put system info formulae into a 
study:
vars: count(0);
if EntryDate(Date) = EntryDate(Date[1]) then
	count = count + 1;
Plot1(count, "whipsaws");


Is this the end of the road for my plans to conquer the markets, or is there a 
way of doing it properly?
Just in case the code looks dumb to you, I just want to point out I'm on TS4 :)
