Error 5002 and 5004

[Sarah Vera]

Hello, I have problems when I run my code in the expert tab it gives me errors 5002 and 5004 2024.08.03 13:06:14.710 LunariaRNNPest (Step Index,H1) Verifying the directory: Common\Files\2 2024.08.03 13:06:14.711 LunariaRNNPrueba (Step Index,H1) Directory verified/created successfully: Common\Files\2 2024.08.03 13:06:14.711 LunariaRNNPreba (Step Index,H1) Trying to create the flag file in: Common\Files\2\Step Index_run_flag.txt 2024.08.03 13:06:14.713 LunariaRNNPrail (Step Index,H1) Error creating flag file for: Step Index. Error: 5004

I am creating this neural network for various symbols. I appreciate your support please

You don't need to specify the Common\Files.

You don't need to specify the Common\Files.

Thank you very much for your correction and helping me.  I did what you told me and created the flag file. But now it tells me trying to open the predictions file. 

But it doesn't open it, I don't understand why it doesn't run it.

It opens it otherwise you would get an error. But it certainly read a prediction=0.

        int prediction_handle = FileOpen(predictions_file_path_corrected, FILE_READ|FILE_CSV|FILE_COMMON|FILE_WRITE|FILE_TXT);

It must be CSV or TXT but not both.

I have deleted text and it still keeps telling me that it is trying to open the predictions file

Of course it is trying to open the predictions files, and it opens it. It's what your code is "saying" to do.

Your problem is unclear.

I made some changes to my code with the suggestion you made for the flag file and everything was perfect. But now it shows me error 5004 when trying to run the predictions file, with the previous code it says that my predictions are 0 which I don't understand because it would be equal to 0 if the predictions file has all its values ​​correct

You are now missing the "\\" in the file path.

I have no idea what is the content of your prediction file, so I can't say if getting a value of 0 is normal or not.

This is the document I am trying to open to run predictions for this asset. It is not normal for the prediction to be 0. The expert advisor should execute the purchases and sales of the asset

Hi, it's me again. I modified the code but in the expert tab it tells me the following: 2024.08.06 18:50:55.354 LunariaRNNPrueba (Step Index,H1) Trying to open the predictions file: 1\Step Index_predictions.csv, I put in the code so that it does not read the header of the first row, but it does not make the prediction. If you can guide me on what I am doing wrong, it is my first neural network. I appreciate your support
