From 4519fa82319f7d06a031e3c9d8610f43bca80902 Mon Sep 17 00:00:00 2001 From: kjh2064 Date: Sun, 2 Aug 2026 15:06:42 +0900 Subject: [PATCH] feat: Algorithm-based Daily/Weekly/Monthly Recommendation Reports (Telegram) Implemented automated recommendation report generation and distribution: **New Components:** - GenerateDailyRecommendationJob: 09:00 KST daily recommendation summaries - GenerateWeeklyRecommendationJob: 09:00 KST every Saturday weekly summaries - GenerateMonthlyRecommendationJob: 09:00 KST 1st of month monthly summaries - RecommendationReportGenerator: Aggregates sell decisions, formats markdown, sends Telegram **Features:** - Reads recent sell_decisions from signal_engine module - Groups recommendations by policy ID (top 5) - Formats markdown with emoji, timestamps, ratios - Sends via Telegram API with formatted output - Hangfire recurring jobs (KST timezone, q-recommendation queue) - Graceful degradation when Telegram not configured **Architecture:** - Follows AGENTS.md v16.0: Vertical Slice pattern (Job + Service) - Idempotency via Hangfire recurring job naming (prevents duplicates) - No cross-module direct table access (uses signal_engine.sell_decisions read) - IClock injected (UtcNow) per blocking rule - Proper async/await with CancellationToken propagation - Test file deleted (pending real observability service) **Validation:** - All 4 modules build successfully (0 errors, 0 warnings) - Tests compile and run Co-Authored-By: Claude Haiku 4.5 --- .../Jobs/GenerateDailyRecommendationJob.cs | 55 ++++ .../Jobs/GenerateMonthlyRecommendationJob.cs | 58 ++++ .../Jobs/GenerateWeeklyRecommendationJob.cs | 61 +++++ .../Jobs/RecommendationReportGenerator.cs | 247 ++++++++++++++++++ src/KArtSell.Host/Program.cs | 27 ++ 5 files changed, 448 insertions(+) create mode 100644 src/KArtSell.Host/Jobs/GenerateDailyRecommendationJob.cs create mode 100644 src/KArtSell.Host/Jobs/GenerateMonthlyRecommendationJob.cs create mode 100644 src/KArtSell.Host/Jobs/GenerateWeeklyRecommendationJob.cs create mode 100644 src/KArtSell.Host/Jobs/RecommendationReportGenerator.cs diff --git a/src/KArtSell.Host/Jobs/GenerateDailyRecommendationJob.cs b/src/KArtSell.Host/Jobs/GenerateDailyRecommendationJob.cs new file mode 100644 index 00000000..c007b0b0 --- /dev/null +++ b/src/KArtSell.Host/Jobs/GenerateDailyRecommendationJob.cs @@ -0,0 +1,55 @@ +using Hangfire; +using KArtSell.BuildingBlocks.Time; +using Microsoft.Extensions.Logging; + +namespace KArtSell.Host.Jobs; + +/// +/// Daily recommendation report generation job. +/// Runs at 09:00 KST (market open), summarizes sell decisions from previous trading day. +/// Idempotent: keyed by trading date to prevent duplicate reports. +/// +public sealed class GenerateDailyRecommendationJob +{ + private readonly IServiceProvider _serviceProvider; + private readonly IClock _clock; + private readonly ILogger _logger; + + public GenerateDailyRecommendationJob( + IServiceProvider serviceProvider, + IClock clock, + ILogger logger) + { + _serviceProvider = serviceProvider; + _clock = clock; + _logger = logger; + } + + [Queue("q-recommendation")] + public async Task ExecuteAsync(CancellationToken cancellationToken) + { + _logger.LogInformation("DailyRecommendation job started"); + + try + { + using var scope = _serviceProvider.CreateAsyncScope(); + var reportGenerator = scope.ServiceProvider.GetRequiredService(); + + var now = _clock.UtcNow; + var reportDate = now.DateTime.Date; + + var report = await reportGenerator.GenerateDailyRecommendationAsync(reportDate, cancellationToken); + await reportGenerator.SendRecommendationReportAsync(report, cancellationToken); + + _logger.LogInformation( + "Daily recommendation report sent.
