How can I find the most effective parameters for a specific currency pair?

This function is called parameter optimization, but I am also more skeptical. If you have experienced a historical retracement of 12 years or more with a specific parameter of EA, it must mean that he can be qualified for the next 5 years or longer. ?

All of this is probability.

Let's talk about how to find these parameters today.

1 you have to download the history data from tickstory.
2 open your mt4 terminal press ctrl + R
3 find the optimization check it.

4 click the EA profit property and change the paras like this pic.

5 click the run button ,and wait for the optimization results. the program will take very long time .

It is very difficult to find a set of parameters suitable for a certain currency, so it has not been optimized recently.
And some adjustments have been made in terms of visualization, such as comments to increase the symbol name and serial number.

I am thinking about a problem recently.
Adapting to it, I am struggling to find a 12-year parameter that matches a currency,
Or is my optimization itself deceiving itself, or is it probable that this optimization can continue to run for the next 12 years without dangerous behavior?

It was found that the filtering of M15 was very serious, and the number of orders was too little, with an average of 8 times per month.

So, now downloading M5 data, it is estimated that it takes some time.

It is now downloaded, can be completed later, and then further tested.

THIS EA IS GRID AND MARTINGALE STRATEGY SO THE SLpercent PARAMETER IS MUST TO SET, IN OTHER WORDS ,HOW MUCH MONEY DO YOU LIKE TO LOSE.
