- src/services/ig-service.js:372-396 (handler)Core implementation of historical prices fetching via IG API endpoint /prices/{epic} with query parameters for resolution, max, pageSize, from, to.
async getHistoricalPrices(epic, resolution, options = {}) { const { max = 10, pageSize = 20, from, to } = options; const params = new URLSearchParams({ resolution, max: max.toString(), pageSize: pageSize.toString() }); if (from) params.append('from', from); if (to) params.append('to', to); try { const response = await this.apiClient.get(`/prices/${epic}?${params}`, 3); return response.data; } catch (error) { logger.error('Failed to get historical prices:', error.message); throw error; } } - src/services/mcp-service.js:702-719 (handler)MCP tool execution handler that extracts arguments and delegates to igService.getHistoricalPrices, formats response as JSON text.
