Expert Advisor optimization

New comment
 
I would like to use the optimization feature in the backtesting, but I don't know how to do it.

What code do I need in my Expert Advisor to turn that feature ON?

Let's say for example, that I want to test for the best EMA:
double emastuff = iMA(NULL,Period(),xxxxx,0,MODE_EMA,PRICE_CLOSE,0);
where 'xxxxx' is the part I want to optimize
 
optimization let You change input parameters. set appropriate start step and stop values in the expert properties and turn on optimization button
 
How do I "set appropriate start step and stop values in the expert properties"?

By using an extern variable in my script?

of course. set external int xxxxx=13; (or so on) and set in the properties it's start step and stop
 
OK Great!

I got it working now.

Thanks!

why dos some values dont work on the strategy tester for example on the macd sample
 
Jannik,

What does your macd code look like?

Slawa,

On the optimizer, I have:

extern int optimize;
start
{
...
TakeProfit = optimize;
...
}

and I set optimize to start=10, step=10, stop=100

it loops through 10 times and it shows 2 results and discards 8.
The 2 that is shows, in the Pass column, it shows 1 and 2, which makes me think 10 and 20 are the best TakeProfit values to use.

Yet, when I set TakeProfit to 50 manually, I get a better net profit with that than when I have it set to 10 manually.
 
ahhhh...

If I rest my mouse on the profit line of the "Optimization Graph", it'll tell me what the value of optimize is.

:)
 
I can also rest my mouse on the grey dot of the "Optimization Results" tab to get my best optimize value.
