Para integrar a funcionalidade de aprendizado de máquina (deep learning neural network) no código de scalping fornecido, manteremos a estratégia original sem alterações e adicionaremos uma rede neural como suporte para aumentar sua assertividade. A rede neural será baseada na estrutura definida no primeiro segmento de código, e será implementada de modo que ela forneça sinais adicionais (de compra e venda) para serem considerados junto às regras originais.

Segue o código modificado para incluir os elementos de rede neural:

### Modificações:
1. **Rede Neural Integrada**: Inclui a configuração da estrutura de rede neural (tensores de pesos e biases), treinamento e previsões.
2. **Treinamento Antes de Começar**: A função `TrainNeuralNetwork` coleta dados históricos de candles e treina a rede neural antes de avaliar novos sinais.
3. **Previsão NN nos Trades**: Os sinais de compra e venda passam pela derivação de alta/baixa (funções `findHigh` e `findLow`) e são analisados também pela rede neural via `SingleForwardPass`.
4. **Compatibilidade**: A rede neural opera dinamicamente e calcula sinais baseados nos candles mais recentes, sem alterar as decisões tradicionais.

Este código usa a previsão da rede neural como mais um sinal na lógica já existente, melhorando a assertividade do robô de scalping. Vale observar que maiores ajustes poderão ser feitos para alinhar a rede às condições específicas do mercado em questão.

Traduis en anglais "Cela fait rêver, puisqu'en Occident c'est tout le contraire : tu connais la chanson, travailler plus pour gagner moins."

"It’s dreamy, because in the West it’s the complete opposite: you know the song, work more to earn less."

Vois-tu une ou des erreurs "Cela fait rêver, puisqu'en Occident c'est tout le contraire : tu connais la chanson, travailler plus pour gagner moins." ?

La phrase en français est globalement correcte et compréhensible, mais on pourrait apporter quelques nuances pour améliorer la clarté ou la fluidité. Voici des commentaires :

1. **Style** : L'expression "Cela fait rêver" est correcte, mais elle pourrait être remplacée par "C'est rêver" ou "Cela paraît idyllique" pour varier le style, selon le contexte.
   
2. **Ponctuation** : Il n’y a pas d’erreurs de ponctuation, mais on pourrait envisager d'utiliser un point-virgule au lieu d'un deux-points pour séparer les deux idées, car elles sont suffisamment liées.

3. **Référence culturelle** : La phrase "tu connais la chanson" est une expression informelle qui fait référence à une idée ou à un concept largement répandu. Assurez-vous que le public comprenne à quoi cela fait allusion.

Voici une version légèrement améliorée en termes de style :

"Cela paraît idyllique, puisque, en Occident, c'est tout le contraire : tu connais la chanson, travailler plus pour gagner moins." 

Cependant, la formulation originale est tout à fait acceptable.

En france on utilise "tu connais la chanson" pour évoquer quelque chose que l'état promet, mais qu'elle ne tient plus compte plus tard, en d'autre terme, la population se fait berner. Existe-il quelque chose de similaire en anglais ?

Oui, en anglais, il existe plusieurs expressions qui peuvent évoquer une situation similaire, où une promesse n'est pas respectée et où la population se sent trompée. Voici quelques-unes :

1. **"We've heard it all before."** - Cela exprime que les promesses ont été faites auparavant sans résultats concrèts.
   
2. **"Promises, promises."** - Cette phrase est souvent utilisée pour indiquer que quelqu'un fait des promesses sans intention sérieuse de les tenir.

3. **"Smoke and mirrors."** - Cela se réfère à des tactiques utilisées pour tromper ou créer une illusion, souvent associées à des promesses non tenues.

4. **"You can't trust politicians."** - Bien que ce soit plus une déclaration qu'une expression idiomatique, elle capture le sentiment que les promesses politiques sont souvent peu fiables.

Ces expressions capturent l'idée que les promesses faites par ceux qui sont au pouvoir ne sont pas toujours tenues, ce qui reflète le sentiment de méfiance ou de désillusion de la population.

Cette phrase exprime aussi le faite, "d'être habitué être trompé par les gouvernants"

Pour exprimer l'idée d'être habitué à être trompé par les gouvernants, on pourrait utiliser des phrases ou expressions qui soulignent la désillusion ou le cynisme face aux promesses politiques. Voici quelques suggestions en anglais :

1. **"It's the same old story."** - Cette expression suggère que l’on s’attend à ce que les mêmes choses se reproduisent, souvent de manière décevante.

2. **"We're used to being lied to."** - Cela exprime directement l'idée d'être habitué à la tromperie.

3. **"Fool me once, shame on you; fool me twice, shame on me."** - Cette proverbiale expression indique qu'après avoir été trompé une fois, une personne devrait être plus méfiante, soulignant une certaine résignation face à la tromperie répétée.

4. **"Once bitten, twice shy."** - Cela signifie qu'après avoir été déçu ou trompé, on est plus prudent à l'avenir.

5. **"Cynicism towards politicians has become the norm."** - Cette phrase peut également évoquer cette idée d'habitude face à la tromperie.

Ces expressions et phrases reflètent un sentiment de méfiance et peuvent transmettre l'idée que les citoyens se sentent habitués à être trompés par leurs gouvernants.

Traduis en anglais "Cela paraît idyllique, puisque, en Occident, c'est tout le contraire : travailler plus pour gagner moins."

"It seems idyllic, because in the West it’s the complete opposite: work more to earn less."

Этот JSON пример включает в себя все основные типы данных JSON и демонстрирует различные возможности:

- **Строки**: значения текста, заключённые в двойные кавычки.
- **Числа**: целые и числа с плавающей точкой.
- **Булевы значения**: `true` или `false`.
- **Null**: специальное значение `null`, обозначающее отсутствие значения.
- **Массивы**: упорядоченные списки значений любого типа, заключённые в квадратные скобки `[]`.
- **Объекты**: коллекции пар "ключ-значение", заключённые в фигурные скобки `{}`.
- **Вложенные объекты и массивы**: объекты и массивы могут быть вложены друг в друга на любую глубину.
- **Специальные символы** и **Юникод**: строки могут содержать специальные символы и символы из разных языков.

Используя этот пример, вы можете увидеть, как различные типы данных и структуры используются в JSON для представления сложных данных.

### Key Notes:
1. `candles` is assumed to be a list of dictionaries containing `imoex2_open` and `gazp_open` values for each data point.
2. SMA (Simple Moving Average) is calculated using NumPy's `convolve` method for fast computation.
3. The behavior and structure of the logic remain close to the Lua code. All initialization and main loop logic is carefully translated to Python.
4. No specific plotting or visual representation is included. You will have to handle signals or graphs within your preferred Python visualization library like `matplotlib`.
