Pine Script Autocomplete String Index Error ✅ **Issue:** Autocomplete was crashing with "string index out of range" error **Location:** `tradingview_mcp/pine_script/autocomplete.py` **Fixes Applied:** - Added comprehensive bounds checking in `_extract_current_word()` - Added bounds checking in `_is_after_dot()` - Added bounds checking in `_get_namespace()` - Added bounds checking in `_find_function_context()` - All cursor position operations now safely handle edge cases **Impact:** Autocomplete now works reliably without crashes ### 2. DataType.SERIES Error ✅ **Issue:** `DataType.SERIES` doesn't exist, causing test failures **Location:** `tradingview_mcp/pine_script/signatures.py:978` **Fix:** Changed `return_type=DataType.SERIES` to `DataType.FLOAT` in request.quandl function **Impact:** All Pine Script validator tests now pass ### 3. Legacy Code Cleanup ✅ **Issue:** 1,695 lines of dead code in `server_old.py` **Fix:** Deleted `tradingview_mcp/server_old.py` **Impact:** Cleaner codebase, easier to navigate --- ## 🚀 New Features ### 1. RSI Indicator ✅ **Description:** Implemented Relative Strength Index (RSI) momentum indicator **Files Changed:** - `tradingview_mcp/indicators/momentum.py` - RSI calculation function (already existed!) - `tradingview_mcp/indicators/__init__.py` - Added RSI export - `tradingview_mcp/server.py` - Added `get_rsi()` MCP tool **Usage:** ```python get_rsi(symbol="AAPL", timeframe="1h", period=14) ``` **Returns:** - RSI value - Signal (OVERBOUGHT/OVERSOLD/NEUTRAL) - Interpretation ### 2. Input Validation System ✅ **Description:** Comprehensive validation utilities for all inputs **New File:** `tradingview_mcp/utils/validators.py` **Validators Added:** - `validate_timeframe()` - Validates timeframe strings - `validate_symbol()` - Validates trading symbols - `validate_period()` - Validates indicator periods - `validate_positive_number()` - Generic number validation - `validate_api_key()` - API key format validation - `ValidationError` - Custom exception class **Impact:** Better error messages, prevents invalid API calls ### 3. Environment Validation ✅ **Description:** Validates API key and environment on server startup **Location:** `tradingview_mcp/server.py` **Features:** - Checks if ALPHA_VANTAGE_API_KEY is set - Validates API key format - Logs warnings for invalid keys - Prevents silent failures --- ## 📚 Documentation Improvements ### 1.
