• src/analytics.ts:361-425 (handler)

  The primary handler function for the 'analyze_trends' tool. It processes different analysis types ('company_trend', 'sector_trend', 'market_trend', 'correlation_analysis') by fetching relevant data from the database, performing calculations, and optionally generating forecasts.

  async analyzeTrends(analysisType: string, target: string, period: number = 30, includeForecast: boolean = false): Promise<any> {
    try {
      const analysis = {
        analysis_type: analysisType,
        target: target,
        period_days: period,
        timestamp: new Date().toISOString(),
        trend_data: null,
        forecast: null,
        insights: []
      };
  
      switch (analysisType) {
        case 'company_trend':
          const company = await this.db.getCompanyBySymbol(target);
          if (!company) throw new Error(`Company ${target} not found`);
          
          const historical = await this.db.getHistoricalPrices(company.id, period);
          analysis.trend_data = this.analyzePriceTrend(historical);
          analysis.insights = this.generateTrendInsights(analysis.trend_data, company);
          
          if (includeForecast) {
            analysis.forecast = this.generateSimpleForecast(historical);
          }
          break;
  
        case 'sector_trend':
          const sectorCompanies = await this.db.getCompaniesBySector(target);
          const sectorPerformance = await this.analyzeCompanyPerformances(sectorCompanies, period);
          analysis.trend_data = {
            sector: target,
            companies_analyzed: sectorCompanies.length,
            average_performance: sectorPerformance.reduce((sum, p) => sum + (p.period_change || 0), 0) / sectorPerformance.length,
            best_performer: sectorPerformance[0],
            worst_performer: sectorPerformance[sectorPerformance.length - 1],
            volatility_measure: this.calculateSectorVolatility(sectorPerformance)
          };
          break;
  
        case 'market_trend':
          const allCompanies = await this.db.getAllCompanies();
          const marketPerformance = await this.analyzeCompanyPerformances(allCompanies.slice(0, 20), period); // Limit for performance
          analysis.trend_data = {
            market: 'IBEX 35',
            companies_analyzed: marketPerformance.length,
            market_direction: this.determineMarketDirection(marketPerformance),
            sector_performance: await this.getSectorCorrelationAnalysis(period),
            volatility_index: this.calculateMarketVolatility(marketPerformance)
          };
          break;
  
        case 'correlation_analysis':
          const correlationData = await this.getSectorCorrelationAnalysis(period);
          analysis.trend_data = {
            ...correlationData,
            correlation_insights: this.generateCorrelationInsights(correlationData)
          };
          break;
      }
  
      return analysis;
    } catch (error) {
      throw new Error(`Trend analysis failed: ${error}`);
    }
  }

• src/index.ts:406-433 (registration)

  Registration of the 'analyze_trends' tool in the MCP server's tool list, including its name, description, and input schema.

    name: 'analyze_trends',
    description: 'Analyze trends in stock prices, market performance, or sector movements over time',
    inputSchema: {
      type: 'object',
      properties: {
        analysis_type: {
          type: 'string',
          enum: ['company_trend', 'sector_trend', 'market_trend', 'correlation_analysis'],
          description: 'Type of trend analysis to perform',
        },
        target: {
          type: 'string',
          description: 'Company symbol, sector name, or "market" for overall analysis',
        },
        period: {
          type: 'number',
          description: 'Number of days to analyze',
          default: 30,
        },
        include_forecast: {
          type: 'boolean',
          description: 'Whether to include simple trend forecast',
          default: false,
        },
      },
      required: ['analysis_type', 'target'],
    },
  },

• src/index.ts:665-672 (handler)

  Dispatch handler in the main server that routes 'analyze_trends' tool calls to the AnalyticsManager's analyzeTrends method.

  case 'analyze_trends':
    result = await this.analytics.analyzeTrends(
      (args as any)?.analysis_type,
      (args as any)?.target,
      (args as any)?.period || 30,
      (args as any)?.include_forecast || false
    );
    break;
