🎯 Trade Visualization Settings

Automatic Trade Arrow System​

BananaEA v4.5.1+ automatically draws colored arrows on your chart showing every trade entry point with full signal classification. This visual feedback system helps you understand pattern distribution, validate signal detection, and review performance without analyzing logs.

🎨 ShowTradeArrows Parameter​

What It Does​

Controls whether BananaEA draws visual arrows on the chart at trade entry points. Each arrow is color-coded by signal type and labeled with the pattern name (Bu1, Be2, etc.).

Configuration​

ShowTradeArrows = true      // Enable automatic arrow visualization
ShowTradeArrows = false     // Disable arrows (cleaner chart)

Default Value​

  • Setting: true (arrows enabled)
  • Why: Visual feedback is valuable for learning and performance analysis
  • Recommendation: Enable during backtesting/demo, optionally disable for live trading

🔍 8 Arrow Types & Color Coding​

BananaEA displays these arrow types:

📏 TradeArrowSize Parameter​

What It Does​

Controls the visual size of arrows drawn on the chart.

Configuration​

TradeArrowSize = 1      // Small arrows (subtle, minimal chart clutter)
TradeArrowSize = 2      // Medium arrows (DEFAULT - balanced visibility)
TradeArrowSize = 3      // Large arrows (maximum visibility, chart analysis)

Default Value​

  • Setting: 2 (medium size)
  • Why: Provides clear visibility without overwhelming the chart
  • Recommendation: Use size 3 during learning phase, size 1 for live trading

🎨 CustomArrowColor Parameter​

What It Does​

Allows overriding the default color scheme with a single custom color for all arrows.

Configuration​

CustomArrowColor = clrNONE      // Use default color scheme (RECOMMENDED)
CustomArrowColor = clrBlue      // Override all arrows to blue
CustomArrowColor = clrGold      // Override all arrows to gold
CustomArrowColor = clrLime      // Override all arrows to lime

Default Value​

  • Setting: clrNONE (default color scheme)
  • Why: Color-coded arrows help distinguish signal types instantly
  • Recommendation: Keep default unless you have visual accessibility needs

📊 MaxBarsToPlot Parameter​

What It Does​

Controls how many historical bars are scanned for signals when EA is first attached to chart. Signals are plotted automatically on chart load.

Configuration​

MaxBarsToPlot = 0        // Real-time signals only (no historical plotting)
MaxBarsToPlot = 100      // Scan last 100 bars (RECOMMENDED)
MaxBarsToPlot = 500      // Scan last 500 bars (detailed analysis)
MaxBarsToPlot = 1000     // Scan last 1000 bars (comprehensive view)
MaxBarsToPlot = 5000     // Maximum - scan last 5000 bars (slow on attach)

Default Value​

  • Setting: 100 bars
  • Why: Provides sufficient historical context without slowing chart attach
  • Recommendation:
    • Learning/Analysis: 500-1000 bars
    • Live Trading: 100 bars
    • Backtesting: 0 bars (reduces processing overhead)

🎨 Visual Customization Tips​

Arrow Positioning​

Arrows are automatically positioned at:

  • Buy arrows: Below the signal bar low (with buffer)
  • Sell arrows: Above the signal bar high (with buffer)
  • Buffer: OffsetPips_B1 = 3 pips (adjustable in Parameters.mqh)

Arrow Labels​

Each arrow includes:

  • Signal Type: "Bu1", "Be2", "Ext", etc.
  • Entry Price: Hover over arrow to see exact price
  • Timestamp: Arrow appears at signal bar time

Arrow Persistence​

  • Backtesting: Arrows remain on chart after backtest completes
  • Live Trading: Arrows stay until EA is removed or chart closed
  • Historical Scan: Arrows load automatically when EA attaches

🔍 Troubleshooting​

Problem: No Arrows Appearing on Chart​

Possible Causes:

  1. ShowTradeArrows = false (disabled)
  2. MaxBarsToPlot = 0 (historical scan disabled)
  3. No signals detected in scan period
  4. EA not fully initialized

Solution:

  1. Verify ShowTradeArrows = true in EA inputs
  2. Set MaxBarsToPlot = 100 or higher
  3. Check EA logs for "Signal detected" messages
  4. Ensure EA shows "Initialized successfully" in Experts log

Problem: Too Many Arrows (Chart Cluttered)​

Possible Causes:

  1. MaxBarsToPlot set too high (e.g., 5000 bars)
  2. EA detecting many signals (working correctly)

Solution:

  1. Reduce MaxBarsToPlot to 100-200 bars
  2. Use TradeArrowSize = 1 for smaller arrows
  3. Zoom out on chart to see broader pattern distribution
  4. Consider ShowTradeArrows = false if not needed

Problem: Arrows Wrong Color​

Possible Causes:

  1. CustomArrowColor overriding default colors
  2. Theme system conflict (rare)

Solution:

  1. Set CustomArrowColor = clrNONE to restore defaults
  2. Restart EA after changing color settings
  3. Verify color in code: Blue=Buy, Red/Orange/Pink=Sell, Purple=External

Problem: Arrows Disappear After Chart Close​

Expected Behavior: Arrows are drawn by EA and don't persist after:

  • EA is removed from chart
  • Chart is closed
  • MT4 is restarted

Solution (if you want permanent markers):

  • Use Trade History Visualizer feature (separate setting)
  • Take screenshots for record-keeping
  • Use MT4 "Save Chart" feature to preserve visual state

📈 Performance Considerations​

Chart Attach Speed​

MaxBarsToPlotAttach TimeCPU ImpactUse Case
0InstantNoneLive trading, backtests
100< 1 secondMinimalRECOMMENDED
5002-3 secondsLowAnalysis, learning
10005-8 secondsMediumComprehensive review
500020-30 secHighHistorical research only

Recommendation: Use MaxBarsToPlot = 100 for optimal balance between performance and visibility.

Visual Rendering Impact​

  • Arrow Drawing: Minimal CPU impact (< 1% typical)
  • Label Rendering: Negligible impact
  • Memory Usage: ~10KB per 1000 arrows (negligible)
  • Chart Responsiveness: No noticeable degradation

Conclusion: Trade visualization has virtually no performance impact on modern systems.

🎓 Best Practices​

✅ DO:​

  • Enable during backtesting for visual validation
  • Use color-coded scheme (default) for pattern recognition
  • Scan reasonable history (100-500 bars) for context
  • Take screenshots of interesting signal clusters for learning
  • Compare with manual analysis to validate EA logic

❌ DON'T:​

  • Scan excessive history (5000 bars) unless researching
  • Override colors unnecessarily - default scheme is optimal
  • Leave enabled on all charts if running multiple EAs (visual clutter)
  • Rely solely on visuals - Always review EA logs for detailed info
  • Forget to adjust when switching demo → live (consider cleaner chart)
