Hello,
when I test my strategy for all 2025, I get for the SPY an APR of +40.3%. However, if I choose instead "most recent 42 weeks" - which is practically the same time range - I get for the SPY an APR pf +50.3%. For my strategy there is even a 40% difference when trying these two settings.
2025: SPY = +40.3% Strategy = +224.4%
Last 42 weeks: SPY = +50.3% Strategy = +184.5%
Is this normal behavior? Or an issue?

What if you run the Strategy again and again without changing any settings? Do the results change each run?
Hi Glitch,
thanks for your answer. The results do not change. They always stay the same.
One theory of mine: If I choose "last 42 weeks" the software would calculate the APR from this period. However, if I choose "year 2025" maybe the software calculates the APR from the full 12 months - with 0% profit for November and December, I don't know. This could explain the effect partly.
I would have another question: There is a Stop Loss order available. I can decide about the percent value which should trigger the stop loss. However, from which price is this percent value calculated? I assume from the last closing price, correct?
Best regards
Werner

It's not the same data. Just look at the first bar in the chart for each range. 2025 will be 1/2/20025. Today, a 43 week range starts 12/30/2025. That's 2 extra bars of data which is certainly enough to influence the first trade and indicators (especially the "unstable indicators").
