Thanks for your prompt response. There is only one thing better than this product and that is the enthusiastic involvement and sharing of ideas in this group.
Your solution has helped me understand another aspect of the stop function and I will certainly play with it.
What I am doing is trying to develope a system along the lines of V K Tharp in TYWTFF.
First step is to look at entries only, and see if one can create entries that give better than even chance of winning, across my chosen markets across all time frames.
Thereafter adding the stops and other exit conditions: this may reduces one's win ratio.
Interesting your simple formula varies win ratio from around 25% on the XAO with good returns using 20 period, to around 70% on my own index of stocks also using a 20 day "stopdays". This is on the last 200 periods.
The win ratio and profitability vary greatly with these simple parameters so I will continue to look for other entries: I am looking for low risk entries, low to moderate profits with smooth equity curve.
Thanks again

Chrisb,
I made some notes in your code below attempting to fix your problems.
Instead of all that, how about trying ApplyStop after N bars and optimize on
N bars? (bars = days on daily data) It won't display percentages exactly,
but it will tell you which number of days makes more money, has lower
drawdowns, etc. Check help on Optimize and ApplyStop for parameter usage.
stopdays = Optimize("Stopdays",5,5,20,5); //Test exits at 5, 10, 15, 20 days
ApplyStop(stopTypeNBar,stopModePoint,stopdays,0,False,5);
//Exit at above periods. Do not re-enter same stock for 5 days.
Put the code after your Buy/Sell conditions.

Sets variable Lastbar to True when the current day is equivalent to the last
day of data. This accomplishes nothing in Explore as it is only true on the
last day of data in your database.

Because Lastbar is only true for today, this is doing anything either

You need to use the Open here...(F1,O) instead of (F1,C)

I'm not sure ValueWhen is valid for AddColumn. You can compute gains in your
code and just display them here...or use my first suggestion.
