+# Portfolio Balance Algorithm
+
+This document describes the portfolio auto-balance algorithm implementation for the TraderBot that uses Deep (associative data storage).
+
+## Overview
+
+The portfolio balance algorithm automatically rebalances a trading portfolio according to predefined asset allocation percentages. This feature allows traders to maintain their desired risk/return profile by automatically adjusting positions when allocations drift beyond specified thresholds.
+
+## Features
+
+### Core Functionality
+- **Automatic Portfolio Analysis**: Continuously monitors current asset allocations vs. target percentages
+- **Deep Storage Integration**: Uses associative data storage (Platform.Data.Doublets) to store portfolio state and decisions
+- **Configurable Thresholds**: Customizable rebalance triggers and check intervals
+- **Multi-Asset Support**: Handles various asset types (ETFs, Shares, Cash, etc.)
+- **Risk Management**: Only rebalances when deviations exceed specified thresholds
+
+### Deep Storage Benefits
+- **Associative Data Model**: Portfolio relationships stored as links between concepts
+- **Rational Number Precision**: Exact decimal calculations without floating-point errors
+- **Query Capabilities**: Efficient queries for portfolio analysis and historical tracking
+- **Data Persistence**: Portfolio state and rebalance history maintained across restarts
+
+## Configuration
+
+### Basic Setup
+Add portfolio balance configuration to your `appsettings.json`:
+
+```json
+{
+  "TradingSettings": {
+    "PortfolioBalance": {
+      "Enabled": true,
+      "RebalanceThresholdPercent": 5.0,
+      "RebalanceCheckInterval": "00:10:00",
+      "AssetAllocations": [
+        {
+          "AssetType": "Gold",
+          "Ticker": "TGLD",
+          "TargetPercent": 25.0,
+          "Instrument": "Etf"
+        },
+        {
+          "AssetType": "USD", 
+          "Ticker": "FXMM",
+          "TargetPercent": 25.0,
+          "Instrument": "Etf"
+        },
+        {
+          "AssetType": "TCS Group stocks",
+          "Ticker": "TCSG", 
+          "TargetPercent": 50.0,
+          "Instrument": "Shares"
+        }
+      ]
+    }
+  }
+}
+```
+
+### Configuration Parameters
+- **Enabled**: Whether portfolio balancing is active
+- **RebalanceThresholdPercent**: Minimum deviation (%) required to trigger rebalancing
+- **RebalanceCheckInterval**: How often to analyze portfolio (format: HH:MM:SS)
+- **AssetAllocations**: Array of target allocations for each asset
+
+## Algorithm Details
+
+### Portfolio Analysis Process
+1. **Portfolio Snapshot**: Retrieve current positions and values
+2. **Allocation Calculation**: Calculate current percentage allocations
+3. **Deviation Analysis**: Compare current vs. target allocations
+4. **Threshold Check**: Identify assets exceeding rebalance thresholds
+5. **Action Generation**: Create buy/sell actions to restore target allocations
+6. **Deep Storage**: Store analysis results in associative format
+
+### Rebalance Logic
+```
+For each asset:
+  current_percent = (current_value / total_portfolio_value) * 100
+  deviation = |current_percent - target_percent|
+  
+  if deviation > threshold_percent:
+    target_value = total_portfolio_value * (target_percent / 100)
+    amount_to_rebalance = target_value - current_value
+    
+    action = amount_to_rebalance > 0 ? BUY : SELL
+    store_in_deep_storage(asset, deviation, action, amount)
+```
+
+### Deep Storage Schema
+The algorithm stores portfolio data using these associative relationships:
+- **Asset → TargetAllocation**: Links assets to their target percentages
+- **Asset → CurrentAllocation**: Links assets to their current percentages  
+- **Asset → RebalanceAction**: Links assets to required rebalance amounts
+- **Portfolio → Type**: Categorizes different portfolio data types
+
+## Example Usage
+
+### Running the Algorithm
+The algorithm runs automatically as part of the TradingService when enabled. It:
+1. Checks portfolio balance at configured intervals
+2. Logs analysis results and required actions
+3. Executes rebalancing for instruments managed by current trading instance
+4. Stores all decisions and state in Deep storage
+
+### Sample Output
+```
+[10:00:00] Starting portfolio balance analysis
+[10:00:01] Asset TGLD: Current 15.2%, Target 25.0%, Deviation 9.8%
+[10:00:01] Asset FXMM: Current 28.5%, Target 25.0%, Deviation 3.5%
+[10:00:01] Asset TCSG: Current 56.3%, Target 50.0%, Deviation 6.3%
+[10:00:02] Rebalance needed for TGLD: Buy 9800.00 RUB
+[10:00:02] Rebalance needed for TCSG: Sell 6300.00 RUB
+[10:00:02] Portfolio analysis complete. 2 rebalance actions identified
+```
+
+## Testing
+
+### Unit Tests
+Run the included tests to verify algorithm functionality:
+
+```bash
+cd TraderBot
+dotnet run --test
+```
+
+### Test Coverage
+- **Portfolio Balance Calculations**: Validates percentage calculations and thresholds
+- **Rebalance Action Generation**: Tests buy/sell decision logic
+- **Deep Storage Integration**: Verifies associative data storage and retrieval
+
+## Integration Notes
+
+### Multi-Instance Coordination
+- Each TradingService instance handles its configured instrument
+- Portfolio-wide rebalancing requires coordination between instances
+- Deep storage provides shared state for cross-instance communication
+
+### Risk Considerations
+- Algorithm respects existing trading rules (time windows, minimum amounts)
+- Cash balance validation before executing buy orders
+- Position validation before executing sell orders
+- Gradual rebalancing to minimize market impact
+
+## Architecture
+
+### Key Components
+- **PortfolioBalanceAlgorithm**: Core analysis and decision engine
+- **PortfolioBalanceSettings**: Configuration model
+- **RebalanceAction**: Action representation with metadata
+- **FinancialStorage**: Deep storage interface for portfolio data
+
+### Deep Storage Benefits
+- **Exact Arithmetic**: Rational numbers prevent rounding errors
+- **Associative Queries**: Efficient relationship-based data access  
+- **State Persistence**: Portfolio history maintained across restarts
+- **Concurrent Access**: Thread-safe storage for multi-instance scenarios
+
+## Future Enhancements
+
+### Planned Features
+- **Historical Analysis**: Track rebalancing performance over time
+- **Advanced Strategies**: Support for momentum-based and volatility-adjusted allocations
+- **Risk Metrics**: Value-at-Risk and correlation analysis
+- **Automated Reporting**: Portfolio performance dashboards
+
+### Deep Storage Extensions
+- **Graph Queries**: Complex portfolio relationship analysis
+- **Machine Learning**: Pattern recognition for optimal rebalancing timing
+- **Distributed Storage**: Multi-node portfolio state synchronization
+
+## Troubleshooting
+
+### Common Issues
+1. **Configuration Errors**: Ensure asset allocations sum to 100%
+2. **API Access**: Verify Tinkoff InvestAPI credentials and permissions
+3. **Storage Issues**: Check Deep storage initialization and memory limits
+4. **Timing Conflicts**: Avoid overlapping rebalance intervals
+
+### Debug Information
+Enable detailed logging by setting log level to "Debug" in configuration:
+
+```json
+{
+  "Logging": {
+    "LogLevel": {
+      "TraderBot.PortfolioBalanceAlgorithm": "Debug"
+    }
+  }
+}
+```
