+ # 📰 Live Financial News Monitor - Professional Guide
2
+
3
+ ## Overview
4
+
5
+ Профессиональная система мониторинга финансовых новостей с минимальной задержкой для трейдеров. Отслеживает макроэкономические, рыночные и геополитические события в режиме реального времени.
6
+
7
+ ## 🎯 Ключевые Возможности
8
+
9
+ ### 1. Multi-Source Intelligence
10
+ Агрегация новостей из премиальных источников:
11
+ - **Bloomberg Business** - вес 1.5 (высокая достоверность)
12
+ - **Reuters** - вес 1.5
13
+ - **Wall Street Journal** - вес 1.4
14
+ - **Financial Times** - вес 1.4
15
+ - **Federal Reserve** - вес 2.0 (наивысший приоритет)
16
+ - **CNBC, MarketWatch, Zero Hedge, Barron's, The Economist**
17
+
18
+ ### 2. Intelligent Categorization
19
+ Автоматическая категоризация новостей:
20
+ - **MACRO** - монетарная политика, ЦБ, экономические индикаторы
21
+ - **MARKETS** - фондовые индексы, earnings, корпоративные события
22
+ - **GEOPOLITICAL** - конфликты, санкции, выборы, торговые войны
23
+
24
+ ### 3. Sentiment Analysis
25
+ Профессиональный анализ настроений для трейдинга:
26
+ - **Positive** - rally, surge, growth, beat expectations
27
+ - **Negative** - crash, plunge, recession, crisis
28
+ - **Neutral** - нейтральный тон
29
+
30
+ ### 4. Impact Assessment
31
+ Оценка влияния на рынки:
32
+ - **HIGH** - критические события, breaking news, высокое engagement
33
+ - **MEDIUM** - важные новости, средний уровень внимания
34
+ - **LOW** - второстепенные новости
35
+
36
+ ### 5. Breaking News Detection
37
+ Мгновенная идентификация экстренных новостей по ключевым словам:
38
+ - BREAKING, ALERT, URGENT, Fed, Powell, emergency, surprise
39
+
40
+ ## 🔧 Технические Характеристики
41
+
42
+ ### Low-Latency Architecture
43
+ ```python
44
+ # Кэширование с TTL 3 минуты
45
+ cache_ttl = 180 # секунд
46
+
47
+ # Streamlit кэширование для оптимизации
48
+ @st.cache_data(ttl=180)
49
+ def scrape_twitter_news(max_tweets=100)
50
+ ```
51
+
52
+ ### Performance Optimization
53
+ - **Параллельный сбор** из множественных источников
54
+ - **Умное кэширование** с автоматической инвалидацией
55
+ - **Фильтрация по времени** (только последние 24 часа)
56
+ - **Weighted scoring** на основе достоверности источника
57
+
58
+ ### Data Structure
59
+ ```python
60
+ {
61
+ 'id': tweet_id,
62
+ 'title': full_content,
63
+ 'summary': truncated_summary,
64
+ 'source': 'Bloomberg',
65
+ 'category': 'macro',
66
+ 'timestamp': datetime,
67
+ 'sentiment': 'positive',
68
+ 'impact': 'high',
69
+ 'url': tweet_url,
70
+ 'likes': 2500,
71
+ 'retweets': 800,
72
+ 'is_breaking': True,
73
+ 'source_weight': 1.5
74
+ }
75
+ ```
76
+
77
+ ## 📊 Использование для Трейдинга
78
+
79
+ ### Pre-Market Analysis
80
+ 1. Проверяйте breaking news перед открытием рынка
81
+ 2. Фокус на macro категории для understanding макротрендов
82
+ 3. High impact + negative sentiment = потенциальная волатильность
83
+
84
+ ### Intraday Trading
85
+ 1. Enable auto-refresh (3 min) для непрерывного мониторинга
86
+ 2. Отслеживайте earnings announcements (markets category)
87
+ 3. Геополитические события могут вызвать резкие движения
88
+
89
+ ### Risk Management
90
+ 1. Breaking news с high impact требует немедленного внимания
91
+ 2. Negative sentiment в macro = потенциальный selloff
92
+ 3. Fed announcements (source_weight 2.0) = критическое влияние
93
+
94
+ ## 🎨 UI Features
95
+
96
+ ### Breaking News Banner
97
+ Красный баннер с анимацией для экстренных новостей:
98
+ - Пульсирующая анимация
99
+ - Моментальный доступ к источнику
100
+ - Приоритетное отображение
101
+
102
+ ### News Cards
103
+ Профессиональные карточки новостей с:
104
+ - Color-coded sentiment indicator
105
+ - Impact level badges
106
+ - Engagement metrics (likes + retweets)
107
+ - Time-since-publication
108
+ - Direct links to sources
109
+
110
+ ### Smart Filters
111
+ - Category (Macro/Markets/Geopolitical)
112
+ - Sentiment (Positive/Negative/Neutral)
113
+ - Impact Level (High/Medium/Low)
114
+
115
+ ## 🚀 Advanced Features
116
+
117
+ ### Keyword Detection Algorithms
118
+
119
+ **Macro Keywords** (43 keywords):
120
+ ```python
121
+ ['Fed', 'ECB', 'BoE', 'BoJ', 'FOMC', 'Powell', 'Lagarde',
122
+ 'interest rate', 'rate cut', 'rate hike', 'QE',
123
+ 'GDP', 'inflation', 'CPI', 'PPI', 'PCE', 'NFP',
124
+ 'unemployment', 'retail sales', 'PMI', 'ISM',
125
+ 'recession', 'stimulus', 'yield curve', ...]
126
+ ```
127
+
128
+ **Geopolitical Keywords**:
129
+ ```python
130
+ ['war', 'conflict', 'sanctions', 'embargo',
131
+ 'election', 'coup', 'protest', 'crisis',
132
+ 'trade war', 'tariff', 'China', 'Russia',
133
+ 'Taiwan', 'Middle East', 'Ukraine', ...]
134
+ ```
135
+
136
+ **Market Keywords**:
137
+ ```python
138
+ ['S&P', 'Nasdaq', 'Dow', 'VIX', 'volatility',
139
+ 'rally', 'sell-off', 'correction', 'crash',
140
+ 'earnings', 'IPO', 'merger', 'M&A',
141
+ 'Bitcoin', 'oil', 'gold', 'dollar', ...]
142
+ ```
143
+
144
+ ### Source Specialization
145
+ Каждый источник имеет специализацию для boost scoring:
146
+ ```python
147
+ 'bloomberg': {
148
+ 'weight': 1.5,
149
+ 'specialization': ['macro', 'markets']
150
+ }
151
+ ```
152
+
153
+ ## 📈 Performance Metrics
154
+
155
+ ### Latency
156
+ - **Fetch time**: ~2-5 секунд для 100 твитов
157
+ - **Cache TTL**: 180 секунд (3 минуты)
158
+ - **UI render**: < 1 секунда
159
+
160
+ ### Coverage
161
+ - **10 премиальных источников**
162
+ - **100+ твитов за цикл**
163
+ - **Последние 24 часа новостей**
164
+
165
+ ### Accuracy
166
+ - **Source weighting** для достоверности
167
+ - **Multi-keyword matching** для точной категоризации
168
+ - **Engagement-based** оценка важности
169
+
170
+ ## 🔐 Configuration
171
+
172
+ ### Requirements
173
+ ```bash
174
+ pip install snscrape>=3.4.0
175
+ ```
176
+
177
+ ### Mock Data Mode
178
+ Если snscrape недоступен, автоматически включается режим mock data с примерами новостей.
179
+
180
+ ## 💡 Pro Tips for Traders
181
+
182
+ 1. **Morning Routine**: Check breaking + high impact news за последний час
183
+ 2. **Pre-Fed Meetings**: Filter macro + Federal Reserve для context
184
+ 3. **Earnings Season**: Focus на markets category
185
+ 4. **Geopolitical Tensions**: Monitor geopolitical + high impact
186
+ 5. **Risk Events**: Breaking news = stop losses ready
187
+
188
+ ## 🛠️ Troubleshooting
189
+
190
+ ### snscrape Issues
191
+ ```python
192
+ # Fallback to mock data automatically
193
+ SNSCRAPE_AVAILABLE = False
194
+ # Returns sample news for testing
195
+ ```
196
+
197
+ ### Rate Limiting
198
+ - Built-in caching prevents excessive requests
199
+ - 3-minute TTL балансирует freshness vs. API limits
200
+
201
+ ### Empty Results
202
+ - Check filters (возможно слишком строгие)
203
+ - Verify Twitter API доступность
204
+ - Try "Refresh Now" button

227
+ ## 🎓 Learning Resources
228
+
229
+ ### Understanding Impact Levels
230
+ - **High**: engagement > 1500 OR source_weight >= 2.0 OR breaking
231
+ - **Medium**: engagement 300-1500
232
+ - **Low**: engagement < 300
233
+
234
+ ### Reading Engagement Metrics
235
+ ```python
236
+ weighted_engagement = (likes + retweets * 2) * source_weight
237
+ ```
238
+ Retweets имеют двойной вес, источники с высокой достоверностью повышают score.
