- Add 'Strategy' tab to sidebar for backtesting simulations
- Create strategy-panel.js for Ping-Pong and Accumulation mode simulations
- Refactor all indicators (MA, HTS, RSI, MACD, BB, STOCH, Hurst) to use strict crossover-based signal calculation
- Update chart.js with setSimulationMarkers and clearSimulationMarkers support
- Implement single-entry rule in Ping-Pong simulation mode
- Create signal-markers.js module to calculate crossover markers for indicators
- Add marker configuration options to indicator config panel:
- Show/hide markers toggle
- Buy/sell shape selection (built-in or custom Unicode)
- Buy/sell color pickers
- Integrate markers with lightweight-charts using createSeriesMarkers API
- Markers recalculate when indicators change or historical data loads
The timeFormatter must be inside localization.timeScale to properly format
time axis labels. This ensures the x-axis time labels display UTC+1 time correctly.
Changes:
1. UTC+1 Time Display
- Updated formatDate() to add 1 hour offset for Central European Time (UTC+1)
- Added timeFormatter to chart timeScale for x-axis labels
- Both signal display and chart time axis now show UTC+1 time
2. Fix Indicator Redrawing
- Added missing getActiveIndicators() call in drawIndicatorsOnChart
- Fixed variable scope issue where activeIndicators wasn't defined
- Ensures indicators are properly removed and recreated when new candles close
Issue 1: Only update lastSignalDate when signal type changes (BUY→SELL or SELL→BUY)
- Modified clearIndicatorCaches() to accept clearSignalState parameter
- When new candle completes: only clear cachedResults/cachedMeta (not signal state)
- When timeframe changes: clear everything including signal tracking
- This preserves signal change history across multiple candles
Issue 2: Indicator lines not updating when new candles arrive
- Added updateIndicatorCandles() function to update existing series
- Instead of removing and recreating series, now uses .setData() to update
- Called when new candle is detected to update indicator lines
- Chart renders correctly with new data after each candle completion
Both issues now resolved:
1. Shows last crossover date only when signal actually changes
2. Indicator lines update in real-time when new candles complete
Changes:
- Added lastCandleTimestamp to track candle completion
- Detect new candle when timestamp increases
- Clear indicator caches when new candle detected
- Clear indicator caches when timeframe changes
- Recalculate indicators and signals in both cases
- Refresh chart when new candle is detected
This ensures indicators are always recalculated with fresh data when:
1. Timeframe is switched
2. A new candle completes
Both cases now force:
- Cache clearing
- Indicator recalculation
- Chart refresh
- Signal recalculation
- Changed date format to DD/MM/YY HH:mm format
- Removed 'Last: ' prefix from signal display
- Added formatDate() helper function for consistent formatting
- Fixed MA plot ID to match return structure (ma vs value)
- Moved Status and Last Signal display to main Indicator Analysis section
- Removed Signal Status section from expanded indicator config
- Simplified signal display to show only status icon/type and last signal date
- Removed strength and reasoning tooltips from signal display
- Add signals-calculator.js module for calculating buy/sell/hold signals for all indicators
- Integrate signals into Trend Analysis panel (renamed to Indicator Analysis)
- Display individual indicator signals with badges, values, strength bars, and detailed reasoning
- Add aggregate summary signal showing overall recommendation from all indicators
- Support signals for RSI, MACD, Stochastic, Bollinger Bands, SMA/EMA, ATR, and HTS
- Provide tooltips on hover showing indicator value, configuration, and reasoning
- Ensure indicators calculate on all available candles, not just recent ones
- Cache indicator calculations for performance while recalculating on historical data loads
- Style improvements: monospace font, consistent button widths, reduced margins
- Add AGENTS.md documentation file with project guidelines
- Remove window.renderIndicatorList() call from renderTA()
- This was triggering initIndicatorPanel during each TF switch
- Added logging to removeIndicatorById to track unexpected deletions
- Removed indicator configuration UI from TA panel (sidebar handles this now)
- Add two-tab navigation (Indicators, Strategies) in right sidebar
- Move all strategy-related content to Strategies tab
- Implement sidebar collapse/expand functionality
- Add indicator visibility toggle (eye button)
- Fix bug where wrong interval data was deleted on TF switch
- Add localStorage persistence for sidebar state and active tab
- Ensure indicators recalculate when TF changes
- Removed automatic TA reload when switching timeframes
- TA panel now only loads on initial page load and when manually refreshed
- User must click Refresh button to update TA after timeframe change
- Fixed TA panel loading state - now waits for initial data before loading technical analysis
- Changed initial loading message from 'Loading technical analysis...' to 'Waiting for candle data...'
- Made strategy simulation sidebar collapsed by default to maximize chart area
- Added refresh timestamp to TA panel when manually refreshed
- Improved error messages for when data isn't available in database
- FastAPI backend with PostgreSQL database connection
- Frontend dashboard with lightweight-charts
- Technical indicators (SMA, EMA, RSI, MACD, Bollinger Bands, etc.)
- Trading strategy simulation and backtesting
- Database connection to NAS at 20.20.20.20:5433
- Development server setup and documentation
