In backtesting, the daily low will be used to see if the trailing stop is triggered. Looking this up, the trailing stop is based off the close, not the high. Here is the Metastock formula for calculating it.
SVE_Stop_Trail%
perc:=Input("Trailing Loss % :",0,100,14);
loss:=C*perc/100;
trail:=
If(C>PREV AND Ref(C,-1)>PREV,
Max(PREV,C-loss),
If(CMin(PREV,C+loss),
If(C>PREV,C-loss,C+loss)));
Trail

How does this do with weekly periodicity, understanding that drawdown and return would probably be compromised in favor of fewer trades?

Shouldn't I be able to sort on column 5 descending, and have either SSO or SDS pop to the top? I thought this would help in backtesting. Didn't seem to work.

By adding the line
ADD COLUMN SEPARATOR
before "add column go_long", the separator becomes column 5. Try sorting on column 6 descending.

Nice, Kevin. Thanks.
Anyone interested in backtesting manually can download (and modify) a stochastics spreadsheet from: http://stochastics.weebly.com/
**Update: Looks like this is not free but you may find the link useful.**

Looking at today's values from stockcharts.com, freestockcharts.com and here on SF, the system will signal a move to go long on SSO at the end of the day (assuming no massive drop that would keep the current SDS trade going).

Kevin,
Looks like SSO triggered long today.
But,,, it looks very oversold with Stochs above 75 and RSI(2) above 90
What do you think?

I will be buying SSO tomorrow at the open, unless there is a gap down that would get me in at a better price.
I have been skeptical of this rally for a while, looking at historical trends for this time of year and also relying on my RS systems, which have me in bonds. But this approach has consistently delivered YTD with a success rate of 75%, and is now up over 50%. We could argue about the meaning of RSI(2) over 90 or any other indicator all day, but you really can't argue with actual performance.
These trades typically last 3-6 days. Any indicator can stay overbought for that long, or longer.

Hello Kevin,
Thank you for sharing this filter.
I am pretty new at this, but I think that for SF Backtest to work, it needs to have in the Advance section "Maximum Entries Per Day" set to "2", so that you can see the two positions being switched on the same day at their respective open price, and "Maximum Open Positions" set to "1", so that you only end up long into one position. It is still not perfect, because sometimes both signals are long, or both signals are short, and SF misses the trade due to the fact that the exit crossover did not happen before or at the same time as the entry crossover. Nevertheless, very impressive results.

Sorry for the rookie question, but I haven't spent any time with stochastics. What are the three inputs represented by Stochastics %D(5,1,5)? Is that the K period, the D period, and the smoothing period?
