Write the file from the indicator dead number when collecting data from different characters. We've been through this. It didn't work....

First of all it is for the test. Secondly, I didn't check it, but according to the idea if the EA initialized an indicator, it starts to work in parallel, so it must also write data and if you have 100 symbols on 100 indicators, they all will be written, what's the problem?

Only if they are attached to the chart, and there is no such a thing... There is only an advisor that refers to the indicator at a certain time..... and no more...

And the indicator will not be able to write the multicurrency. Tested. I think I already said it, because we have moved from this scheme to the advisor... Checked it already....

So, when you call the indicator through the Handle from the EA, the file operations are cut, right? I have not checked it myself yet.

I need to spar such a tree into a working function in mql, how easy is it to do?

I can't help you here...

Get into the package and look at the tree)

Get in the bag and look at the tree)

Are you good at parsing in python? I did half of it, I had no time yet. All that's left is to put the brackets in.

Nah, parsing is always a pain for me) and I'm just learning python) and I have no time for it...
 
Valeriy Yastremskiy:
No, parsing is always a pain for me) and I'm learning python now) and time is tight...
Stanislav Korotky
He's definitely better than me and many others at parsing
 

Let's say I did, but there are not enough closing parentheses, highlighted in red what I need to add. What's the best way to calculate where the brackets are missing and add? Purely logically

double decision_tree(double &features[]) { 
    if ( 55 1 <= 0.000465 )  {
        if ( 45 1 <= -0.000285 )  {
            if ( 50 1 <= -0.00062 )  {
                return 1; }
            if ( 50 1 > -0.00062 )  {
                if ( 25 1 <= -0.00034 )  {
                    if ( 35 1 <= -0.000705 )  {
                        return 1; }
                    if ( 35 1 > -0.000705 )  {
                        return 0; } }
                if ( 25 1 > -0.00034 )  {
                    if ( 35 1 <= -0.000525 )  {
                        return 0; }
                    if ( 35 1 > -0.000525 )  {
                        if ( 55 1 <= -0.000145 )  {
                            if ( 25 1 <= -0.00021 )  {
                                if ( 50 1 <= -0.000375 )  {
                                    return 0; }
                                if ( 50 1 > -0.000375 )  {
                                    return 1; } }
                            if ( 25 1 > -0.00021 )  {
                                return 1; } }
                        if ( 55 1 > -0.000145 )  {
                            return 0; }

why not replace several if( condition_1 ) if( condition_2 )

to if( condition_1 && condition_2)

it's easier to search for closing parentheses, the code is faster to read, in general, more convenient, imho.
