News Bias Engine — Real-Time Economic Calendar with Post-News Directional Bias
Most news indicators show you WHEN events happen.
News Bias Engine tells you WHAT TO DO after they happen.
═══════════════════════════════════════════════════════════════
THE PROBLEM WITH STANDARD NEWS INDICATORS
Every economic calendar tool on the market does the same thing:
displays upcoming events with countdown timers. That's useful, but
it's only half the job. The real question after NFP, CPI, or an
FOMC release is always the same:
"Did the data come out better or worse than expected, and what
does that mean for the pair I'm trading right now?"
Standard indicators leave you alone with that question. You have to
mentally compute the surprise, remember which currency reacts which
way, and translate it to your symbol — all while the market is
already moving.
News Bias Engine does this for you, automatically, in real time.
═══════════════════════════════════════════════════════════════
CORE FEATURES
▸ NATIVE MT5 CALENDAR — Zero external APIs, zero WebRequest, zero
DLLs. Uses MetaTrader's built-in economic calendar. Works on any
broker that provides calendar data.
▸ POST-NEWS BIAS ENGINE — After each release, computes a directional
bias on your current symbol based on:
• Surprise magnitude (actual vs forecast, normalized %)
• Event importance weighting (HIGH × 2.0, MEDIUM × 1.0, LOW × 0.5)
• Time decay with configurable half-life (default 120 min)
• 95+ built-in currency reaction rules for top economic events
▸ ENGLISH EVENT NAMES — All events are translated to standardized
English labels automatically, regardless of your MT5 terminal
language. A trader using an Italian terminal and a trader using
an English terminal see the same clean labels: "Industrial
Production", "Non-Farm Payrolls", "Empire State Mfg Index",
"Corporate Goods Price Index", etc. Toggleable.
▸ AUTO-SYMBOL FILTERING — Open EURUSD: see only EUR and USD events.
Open XAUUSD: see only USD events. Open GBPJPY: see only GBP and JPY
events. No manual configuration needed.
▸ THREE-STAGE STATUS SYSTEM
• CLEAR — Safe to trade
• CAUTION — High-impact event approaching (configurable window)
• BLACKOUT — Active event window, avoid new trades
• WARN — Calendar unavailable (broker issue, with details)
▸ ON-CHART VERTICAL LINES — Visual markers on the chart at every
high-impact event timestamp. Tooltip shows event details on hover.
▸ PERSISTENT ALERTS — Sound, popup, and push notifications X minutes
before high-impact events. Alert state survives terminal restarts:
you never get duplicate alerts for the same event.
▸ CONFIDENCE SCORING — Each bias comes with LOW/MEDIUM/HIGH
confidence based on event count and cumulative strength.
▸ ROBUST ERROR HANDLING — Validates all inputs at startup. Detects
empty/unavailable calendar feeds and displays a clear warning
instead of failing silently.

HOW THE BIAS ENGINE WORKS — CONCRETE EXAMPLE
Scenario: You are trading XAUUSD. US Empire State Manufacturing
Index is released:
Actual: +19.60
Forecast: -3.40
Surprise: Strong positive beat
News Bias Engine computes:
• Surprise direction: positive
• Magnitude bucket: 3x (>25% surprise)
• Event importance: MEDIUM (×1.0)
• Empire State rule weight: 1.0
• Time decay (5 min after release, half-life 120 min): ×0.97
• USD polarity for positive surprise: +1 (bullish)
• Combined USD score: +2.9
For XAUUSD this translates to:
• Strong USD = bearish for gold (metal/USD inverse correlation)
• Symbol bias: SHORT XAUUSD
• Strength: 2.9
• Confidence: LOW (single MEDIUM-impact event)
You see this on screen within seconds of the release.

FREQUENTLY ASKED QUESTIONS
Q: Does it work on demo accounts?
A: Yes. Works on demo and live accounts identically.
Q: Does my broker need to provide an economic calendar?
A: Yes. MT5's calendar is broker-dependent. Most major brokers
provide it. If your broker does not, the indicator will display
a WARN status in the panel. Test on a demo account first if
unsure.
Q: Will the bias work for every event?
A: The bias is computed only for events that have BOTH actual and
forecast values, AND that match one of the 95+ rules. Minor
reports without forecast consensus (e.g. CFTC positions, Baker
Hughes rig count) are tracked for awareness but do not contribute
to bias. This is intentional — you cannot compute a surprise
without a forecast.
Q: My terminal is not in English. Will event names display correctly?
A: Yes. By default, News Bias Engine translates event names to
standardized English labels using a built-in dictionary covering
200+ event patterns. You can disable this in settings if you
prefer your terminal's native language.
Q: Can I use it for scalping?
A: Yes. Set "event weight halves every N minutes" to 30 or 60 for
faster decay. Set "consider releases up to N hours back" to 2 or 3.
Q: Can I use it for swing trading?
A: Yes. Set half-life to 240+ minutes and lookback to 24h.
Q: Does it work on all timeframes?
A: Yes. Panel and calendar logic are timeframe-independent.
Q: Does it auto-trade?
A: No. This is an analytical indicator, not an Expert Advisor. It
gives you the bias; you decide whether and how to trade it.
Q: What if the calendar is empty in MT5?
A: The panel shows a WARN status with the reason. Check Tools →
Options → Server that your broker provides the calendar feed.
