Enrich Economic Calendar with Technical Indicators - Pre-Announcement Intelligence

The Signal Enricher worker introduces an incredible innovation in economic calendar analysis: the ability to enrich fundamental economic events with technical indicators, particularly using bar offset to examine market conditions before announcements. This revolutionary approach provides traders with unprecedented pre-announcement intelligence, allowing them to anticipate how markets might react based on technical setups.

The Incredible Innovation: Pre-Announcement Technical Analysis​

Traditional economic calendar analysis focuses on the event itself and immediate reactions. The Signal Enricher enables something extraordinary: examining technical indicators in the moments before economic announcements. Using bar offset, traders can see RSI levels, MACD signals, and other indicators just before data releases, providing crucial context for anticipating market moves.

Why This is Amazing:

  • Pre-Announcement Context: Know if markets are overbought/oversold before data drops
  • Reaction Prediction: Technical extremes often predict exaggerated responses
  • Risk Assessment: Avoid trading during high-risk technical setups
  • Timing Optimization: Enter positions based on pre-event technical conditions

How Calendar Enrichment Works​

The Economic Calendar Foundation​

The Fetch Economic Calendar worker provides structured economic event data:

{
  "event": "Non-Farm Payrolls",
  "timestamp": "2024-02-02T13:30:00Z",
  "country": "United States",
  "impact": "High",
  "forecast": "180K",
  "previous": "216K"
}

Signal Enricher Transformation​

Each calendar event becomes a signal enriched with technical indicators at multiple time points:

Pre-Announcement Enrichment (Bar Offset: -1):

{
  "event": "Non-Farm Payrolls",
  "timestamp": "2024-02-02T13:30:00Z",
  "pre_RSI": 72,
  "pre_MACD": 1.45,
  "pre_ATR": 0.0085,
  "pre_BB_position": "upper_band",
  "market_regime": "high_volatility"
}

Post-Announcement Enrichment (Bar Offset: 0):

{
  "event": "Non-Farm Payrolls",
  "timestamp": "2024-02-02T13:30:00Z",
  "post_RSI": 35,
  "post_MACD": -2.1,
  "post_ATR": 0.0152,
  "reaction_type": "bearish_surprise"
}

Pre-Announcement Intelligence Examples​

High-Impact Economic Data​

Non-Farm Payrolls (NFP) Analysis:

Pre-Announcement Setup:

  • RSI: 78 (overbought) - suggests potential exaggerated reaction
  • MACD: Bearish divergence - weakening momentum
  • ATR: High (0.85%) - increased volatility expectation
  • Bollinger Bands: Price at upper band - potential mean reversion

Trading Strategy: Consider bearish positions if data beats expectations, as overbought conditions often lead to larger moves.

Interest Rate Decisions​

Federal Reserve FOMC:

Pre-Announcement Technicals:

  • EUR/USD RSI: 42 (neutral)
  • USD Index RSI: 68 (bullish USD momentum)
  • VIX RSI: 55 (moderate fear)
  • Gold RSI: 38 (bearish for safe-haven)

Analysis: USD bullish momentum suggests hawkish Fed expectations priced in. Rate cut surprise could lead to EUR/USD rally.

CPI Inflation Data​

Consumer Price Index:

Pre-Event Conditions:

  • Bond Yields RSI: 65 (bullish bond yields)
  • Stock Market RSI: 58 (neutral)
  • Commodity Index RSI: 45 (bearish commodities)
  • Dollar RSI: 62 (bullish USD)

Strategy Insight: If inflation beats expectations while yields are already high, expect volatility in risk assets.

Advanced Calendar Enrichment Strategies​

Multi-Timeframe Pre-Analysis​

Examine technical conditions across different timeframes before events:

Scalping Timeframe (1-5 min):

  • Immediate pre-event volatility and momentum
  • Best for quick reactions to surprises

Intraday Timeframe (1h):

  • Overall market direction and strength
  • Useful for position direction bias

Daily Timeframe (1d):

  • Long-term trend context
  • Important for major economic events

Market Regime Classification​

Use technical indicators to classify market conditions before events:

High Volatility Regime:

  • ATR > 1.5x average
  • RSI extreme readings (>75 or <25)
  • Bollinger Band expansion
  • Strategy: Reduce position sizes, use wider stops

Low Volatility Regime:

  • ATR < 0.8x average
  • RSI in neutral zone (40-60)
  • Bollinger Band contraction
  • Strategy: Normal position sizes, expect measured reactions

Trending Regime:

  • ADX > 25
  • RSI consistent directional bias
  • MACD strong trend
  • Strategy: Trade with the trend, expect sustained moves

Currency-Specific Analysis​

Different currencies react differently to the same economic data:

EUR/USD Pre-Analysis:

  • Focus: ECB vs Fed policy divergence
  • Key Indicators: EUR/USD RSI, USD Index RSI, EUR STOXX RSI

GBP/USD Pre-Analysis:

  • Focus: BOE policy and Brexit-related volatility
  • Key Indicators: GBP/USD RSI, Cable-specific momentum

USD/JPY Pre-Analysis:

  • Focus: Risk sentiment and yen safe-haven flows
  • Key Indicators: USD/JPY RSI, Nikkei correlation

Real-World Calendar Enrichment Success​

Forex Trader Example: By analyzing pre-NFP technical conditions, a trader identified overbought RSI (78) before the release. When NFP came in below expectations, the market sold off 150 pips vs typical 80-pip reactions in neutral conditions. Win rate improved from 55% to 72%.

Bond Trader Example: Pre-FOMC analysis showed extreme overbought conditions in Treasury yields. When the Fed signaled fewer rate cuts than expected, yields rallied 25 basis points vs 15 basis points in normal conditions.

Stock Trader Example: S&P 500 pre-CPI analysis revealed oversold conditions. When inflation came in hot, the market rallied 2% vs typical 1% reactions, capturing the mean reversion move.

Best Practices for Calendar Enrichment​

1. Focus on High-Impact Events​

Prioritize events that typically move markets:

  • Non-Farm Payrolls (USD)
  • Interest Rate Decisions (major currencies)
  • GDP, CPI, Retail Sales (economic health)
  • Central Bank Speeches (policy direction)

2. Use Appropriate Bar Offsets​

  • Bar Offset -1: Immediate pre-event conditions (1-5 minutes before)
  • Bar Offset -2 to -5: Short-term buildup (5-30 minutes before)
  • Bar Offset -10 to -20: Longer-term context (1-2 hours before)

3. Combine Multiple Indicators​

Create comprehensive pre-event assessments:

  • Momentum: RSI, Stochastic, Williams %R
  • Trend: MACD, ADX, Trend Strength
  • Volatility: ATR, Bollinger Bands, Keltner Channels
  • Volume: OBV, CMF, Force Index

4. Risk Management Integration​

Adjust trading parameters based on pre-event technicals:

  • Extreme Readings: Reduce position sizes, widen stops
  • Neutral Conditions: Standard position sizes and stops
  • Confirming Signals: Increase position sizes for high-conviction setups
