Maybe this will help?

Or compile.
Thenon the Error tab, double click on the first error.
Cursor will go where there is no closing bracket.
And so for every bracket, double clickon error, put the bracket, compile.

The task - to generate in python a working mql code, why tinker with it?

almost done

I think I've figured out that you can't do it off-line....

the portfolio is really something....

voila

would have been exhausted in debugger :D

that's not the biggest tree you can get

double decision_tree(double &features[]) {

Checking that the tree works the same way.

On mql:

2020.07.11 23:17:15.120 code check (EURUSD,M5)  Result 2.0
2020.07.11 23:17:15.121 code check (EURUSD,M5)   0.00000  0.00030  0.00031  0.00019  0.00005 -0.00009 -0.00014 -0.00014 -0.00008 -0.00025 -0.00014 -0.00038

In python:

lll = [0.00000,  0.00030,  0.00031,  0.00019,  0.00005, -0.00009, -0.00014, -0.00014, -0.00008, -0.00025, -0.00014, -0.00038]
lll = np.array(lll).reshape(1,-1)
clf.predict(lll)

>>> clf.predict(lll)
array([2])

I think I figured out that you can't do it off-line....

the briefcase is a real piece of work....

It's doing great off-line. I've tested it.

It makes my fur coat turn.

There was an error.

Roman, look for an error in yourself, it should work fine on the story

;)

i found it, i found the flaw in the strategy!!!

Pre-testing up to 10x per day

what happens now........

CatFx50 I get an error Questions from Beginners MQL5

@Maxim Dmitrievsky Is the parser still needed?

off-line lives just fine, I tested it

It makes my fur coat curl.

There was a stupid error.

Pre-testing up to 10x per day

what's going to happen now........

So I did not say that it does not work on history :)))
I said that I have not finished for history, and postponed the development.
And so, the preparation of historical data, this is one of the important stages.
And all models are built, tested, taking into account history.
That's statistics ))
Good for you that everything is working out.

Maxim Dmitrievsky 2020.07.12 04:52 #18618

Nanix:
@Maxim Dmitrievsky do you still need a parser?

Thanks, brackets are still missing, for example here

if(L_55_1  >  0.00047) {
    if(L_30_1  <= 0.00044)
        { return 2;}
    if(L_30_1  >  0.00044) {
        if(L_25_1  <= 0.00047) {
            if(L_5_1  <= 0.00012)
                { return 0;}
            if(L_5_1  >  0.00012)
                { return 2;} }
        if(L_25_1  >  0.00047) return 2; } }

the red ones are as they should be.

Mine does it all. Otherwise, the conditions will not work correctly and the tree will count the wrong

From your codes I roughly began to understand how trees work. Weak algorithm compared to polynomial, in my opinion so....
