how do you think optimize a strategy not too much?

[cf0532]

when we optimize a strategy by parameters, we should comfirm this is not too much.
Take for an example, define a parameter 'a';
if 'a' > 0, we long; else we short;

Create a strategy with only this one parameter, I think we can't confirm this strategy optimized too much if we only test 10 trades; but if we test 100 trades, maybe we can confirm this strategy is ok;

Others we should consider many parameters and evaluate the strategy;
Is there a system method for evaluating like this?

English, that wonderful language...

I think you are after a way to measure your strategy's performance. You can look at metrics like:

Also if you take a look at trading journals you will see a report there that can shed some light.

THAT maybe ok, cf0532,100 trades of months, 120 months total, maybe ok. So it gets a bull + bear trend cycle, to be ok.
All the data;
+ 4,000+ years if available, with discretion, is even better
