MT5 Multi-Symbol Price Action Market Filter (Alerts Only, No Auto-Trading)

1. Trading Idea & Project Goal

This is a Market Filter Scanner, not a trading robot. Its sole purpose is to automate the identification of high-probability price action setups across multiple symbols.

The tool must scan markets, apply a strict set of objective rules to closed candles only, and alert me with a sound when a setup is found. This MVP (Minimal Viable Product) version is deliberately simplified to focus budget on the core logic. Future upgrades (dashboard, push notifications) may be considered separately.

❌ ABSOLUTELY NO TRADE EXECUTION. This is a scanner/alert tool only.

2. Definitions (Mathematical Rules)

All logic uses closed candles only. The currently forming candle is never evaluated.

• Swing High/Low: A bar where its High/Low is greater/lower than the  LeftBars  bars before and  RightBars  bars after it. A swing is confirmed only after  RightBars  subsequent bars have closed.

• H1 Trend:

  • Uptrend: Last confirmed Swing High > Previous one AND Last confirmed Swing Low > Previous one.

  • Downtrend: Last confirmed Swing High < Previous one AND Last confirmed Swing Low < Previous one.

  • Range: Any other condition. This results in immediate rejection.

• 35% Location Zone (H1):

  • Range = Confirmed_H1_SwingHigh − Confirmed_H1_SwingLow

  • Premium Zone:  Price > (SwingHigh − (Range × 0.35))

  • Discount Zone:  Price < (SwingLow + (Range × 0.35))

• Candle Body %:  (MathAbs(Close − Open) / (High − Low)) × 100

• Body Overlap > 50%: For two consecutive candles, the formula is:  Overlap = MathMax(0, MathMin(Open1, Close1, Open2, Close2) - MathMax(Open1, Close1, Open2, Close2)) . Condition is true if  (Overlap / MathMin(BodySize1, BodySize2)) > 0.50 .

3. Core Signal Logic (Sequential - Fail Fast)

The system evaluates each symbol in a watchlist on every closed M15 candle. Rules are checked in order. If any fail, evaluation stops (Tier C/Reject).

1. Rule 1 - H1 Trend: Must be Uptrend or Downtrend. If Range → Reject.

2. Rule 2 - M15 Alignment: The most recent confirmed M15 swing must align with the H1 trend direction (e.g., Higher Low in an uptrend). If counter-trend → Reject.

3. Rule 3 - Location: Price must be in the correct extreme zone (Discount for long in uptrend, Premium for short in downtrend). If mid-range → Reject.

4. Rule 4 - Momentum (M15):

   • Two consecutive M15 candles close in the trend direction.

   • The second candle closes beyond a recent M15 swing level.

   • Tier A: Both candles have  Body % ≥ 65 .

   • Tier B: At least one candle has  Body % ≥ 50 .

   • If not met → Reject.

5. Rule 5 - Chop Filter: Analyze last 10 M15 candles. If 5+ consecutive pairs have  Body Overlap > 50%  → Reject.

4. OUTPUT REQUIREMENTS (SIMPLIFIED - MVP CORE)

This section is strict. Proposals adding the excluded features below will not be considered.

• Primary Alert: A clear, distinct audible alert (play a sound file) when any scanned symbol meets Tier A or Tier B criteria.

• Primary Log: Print a message to the MT5 "Experts" tab with this format:
  [Timestamp] ALERT: [SYMBOL] - Tier [A/B] - H1 Trend [Up/Down]

• Classification: The internal logic must correctly classify each symbol as Tier A, B, or C (Reject).

✅ WHAT IS INCLUDED (MVP Scope):

• The core 5-rule scanning logic applied to a user-defined symbol list.

• Audible alert on Tier A/B.

• Expert tab log.

❌ WHAT IS EXPLICITLY EXCLUDED (To Reduce Cost/Complexity):

• Push notifications to mobile.

• Graphical dashboard or table.

• On-chart drawing (shading, lines).

• Automatic session time filters.

• Any form of trade execution.

5. Input Parameters (Configurable)

• SymbolList : Comma-separated symbols (e.g.,  EURUSD,GBPUSD,XAUUSD ).

• Swing_LeftBars ,  Swing_RightBars : For swing detection.

• LocationZonePercent : Default 35.

• TierA_BodyPercent ,  TierB_BodyPercent : Default 65 and 50.

6. Deliverables

• Compiled  *.EX5  file.

• Full, well-commented  *.MQ5  source code.

• A distinct sound file (e.g.,  alert.wav ) configured in the code.

7. Budget & Timeline

• Budget: $200 - $400 (Fixed price or negotiable within this range).

• Timeline: 7-14 days for delivery and basic testing.

We are looking for a developer who specializes in custom MQL5 logic and respects a clear, fixed scope. Please bid only if you understand the mathematical definitions and the "No Trading/No Dashboard" constraint.
