# Enhanced Trading Bot - Issue #103 Implementation
2+
3+
This implementation provides a complete solution for issue #103, creating the "Simpliest possible trading bot, that uses associative data storage (Deep or Doublets)."
4+
5+
## 🎯 Features Implemented
6+
7+
### ✅ Core Requirements Met
8+
9+
1. **Real Trading API Support** - Tinkoff Invest API integration
10+
2. **Simulation API Support** - Built-in simulation with realistic price movements
11+
3. **TRUR ETF Trading** - Direct support for the target ETF
12+
4. **Performance Goal** - 1% annual outperformance tracking and validation
13+
5. **Replaceable APIs** - Pluggable architecture for different brokers
14+
6. **Replaceable Strategies** - Interface-based strategy system
15+
7. **Links Notation Configuration** - Support for Links Platform config format
16+
8. **Doublets Associative Storage** - Full integration with Platform.Data.Doublets
17+
18+
### 🧠 Advanced Trading Strategy
19+
20+
Implemented the **Optimal Bid Strategy** from issue comments:
21+
- Each day maintains half ETF, half cash for optimal performance
22+
- N buy orders (movable) and N sell orders (non-movable)
23+
- Buy orders automatically move up when empty slots appear
24+
- Designed for non-volatile ETFs like TRUR
25+
- Self-balancing portfolio management
26+
27+
## 📁 Architecture
28+
29+
### Core Components
30+
31+
1. **ITradeApiProvider** - Abstraction for trading APIs
32+
- `SimulationTradeApiProvider` - Local simulation
33+
- `TinkoffTradeApiProvider` - Real Tinkoff API
34+
35+
2. **ITradingStrategy** - Strategy interface
36+
- `OptimalBidTradingStrategy` - Main strategy implementation
37+
38+
3. **FinancialStorage** - Doublets-based data storage
39+
- Trading operations storage
40+
- Portfolio balance tracking
41+
- Performance metrics persistence
42+
43+
4. **PerformanceTracker** - Performance monitoring
44+
- Real-time portfolio tracking
45+
- ETF benchmark comparison
46+
- 1% annual outperformance validation
47+
48+
5. **LinksNotationConfigurationProvider** - Configuration system
49+
- Links Notation format support
50+
- Fallback to traditional JSON config
51+
52+
## 🚀 Usage
53+
54+
### Quick Start (Simulation Mode)
55+
```bash
56+
cd /tmp/gh-issue-solver-1757745128855/csharp/TraderBot
57+
dotnet run --configuration Enhanced
58+
```
59+
60+
### Real Trading Mode
61+
1. Get Tinkoff Invest API token
62+
2. Update `appsettings.Enhanced.json`:
63+
```json
64+
{
65+
"UseSimulation": false,
66+
"InvestApiSettings": {
67+
"AccessToken": "your-token-here"
68+
}
69+
}
70+
```
71+
72+
## 📊 Performance Tracking
73+
74+
The bot automatically tracks:
75+
- Portfolio value over time
76+
- ETF buy-and-hold benchmark
77+
- Outperformance metrics
78+
- Achievement of 1% annual goal
79+
80+
Reports are generated showing:
81+
- Total returns vs ETF performance
82+
- Annualized returns and outperformance
83+
- Trading activity statistics
84+
- Goal achievement status
85+
86+
## ⚙️ Configuration
87+
88+
### Links Notation (config.lino)
89+
```
90+
(etf_ticker "TRUR")
91+
(cash_currency "rub")
92+
(strategy_name "OptimalBid")
93+
(number_of_bids 5)
94+
(use_simulation true)
95+
```
96+
97+
### JSON (appsettings.Enhanced.json)
98+
Traditional configuration format with full settings for trading parameters, API credentials, and strategy options.
99+
100+
## 📈 Trading Strategy Details
101+
102+
The **Optimal Bid Strategy** implements the exact approach described in issue #103:
103+
104+
1. **Portfolio Balance**: Maintains 50% ETF, 50% cash
105+
2. **Bid Management**: Places N buy and N sell orders around current price
106+
3. **Dynamic Adjustment**: Buy orders move up automatically when gaps appear
107+
4. **Risk Management**: Sell orders remain fixed to secure profits
108+
5. **Market Following**: Adapts to price movements while maintaining structure
109+
110+
## 🗃️ Data Storage
111+
112+
Uses **Doublets associative database** for:
113+
- **Operations**: All buy/sell transactions with timestamps
114+
- **Balances**: Portfolio states over time
115+
- **Performance**: Snapshots for tracking and analysis
116+
- **Configuration**: Trading parameters and strategy settings
117+
118+
This provides:
119+
- Fast associative queries
120+
- Efficient storage
121+
- Complex relationship modeling
122+
- Integration with Links Platform ecosystem
123+
124+
## 🎁 Bonus Features
125+
126+
- **Multiple strategies support** - Easy to add new trading strategies
127+
- **Comprehensive logging** - Debug and production logging levels
128+
- **Error recovery** - Robust error handling and recovery mechanisms
129+
- **Extensible architecture** - Clean interfaces for future enhancements
130+
- **Performance reports** - Automated reporting on trading effectiveness
131+
132+
