How to tell if a stategy is good

Hey all, new zorro S user here. New to finance and looking to understand basic terminology. I've run a few interesting optimizations and tests, but I don't understand the results. (see image)

When I increase the Capital variable at the start of my script, the return drops. I don't get it! Also, with a high annual return I would expect the equity graph to be more blue, but it looks about 50 / 50. How can I interpret this?

Thank you!

Since return is profit per Capital, if you increase your capital by 100% and profit stays the same, your return will drop by 50%.

I appreciate the answer. I'm having trouble wrapping my head around it. Let's say I use a date range of 30 days for my backtest. I would like to know, if it starts out with 100$, how much will it end up with after the 30 days. Annual return is estimated I assume. What is the best way to look at this data to determine if it would be profitable? Forgive my ignorance I don't have much of a finance background.

If this it hard to understand.. if a strategy makes 10% per year, why does the starting capital affect the outcome? Shouldn't it return be 10% of whatever capital is put into it?

Has nothing to do with finance but with basic math.
Say you make $1,000 a year, then this would be 10% with a starting capital of 10,000 but with a starting capital of 100,000 this would only be 1%.

I dont know your strategy but when return drops by increasing capital, you're not investing your capital properly. Or not at all.
