This commit finalizes the migration of the MultiTimeframeZone Expert Advisor from MQL5 to MQL4.
- Moved all source code, documentation, and expert files from the MQL5 directory to the MQL4 directory.
- Deleted the now obsolete MQL5 directory and its contents.
- Updated the IMPLEMENTATION_SUMMARY.md to reflect the current MQL4-focused implementation.
- Add mql4-syntax-critical.instructions.md: Complete syntax rules for MQL4
- Add mql4-experts.instructions.md: Expert Advisor development guidelines
- Add mql4-indicators.instructions.md: Custom indicator development guidelines
- Add mql4-scripts.instructions.md: Script development guidelines
- Update copilot-instructions.md: Add language-specific instruction routing
- Include MQL4 vs MQL5 comparison table and workflow guidance
- Based on real-world experience from MultiTimeframeZone EA development
PART 1 - Demo Period Protection:
================================
Added expiry check in OnInit() function:
- Expiry date: December 31, 2025 23:59:59
- Compares current date with expiry date
- If expired:
* Returns INIT_FAILED (EA stops loading)
* Prints detailed expiry message to Journal
* Shows Alert popup with developer contact
* Displays message on chart via Comment()
- If valid:
* Logs days remaining in demo period
* EA continues normal operation
Developer Contact: rahuldhangar@gmail.com
PART 2 - M15 Zone Deletion (FIXED):
====================================
Problem: M15 zones never deleted after order closes
Solution: Enhanced ManageOpenPositions() to:
- Check all M15 zones with placed orders
- Detect when orders move to history (closed)
- Identify close reason:
* TP Hit (with profit amount)
* SL Hit (with loss amount)
* Break-even close
* Order cancelled/rejected
- Automatically delete M15 zone when order closes
- Log detailed close reason
PART 3 - H4 Zone Deletion (FIXED):
===================================
Problem: H4 zones not deleted after SECOND break
Strategy: Create Break Reverse Break Delete
Fixed CheckH4Breaks() function:
- First break: Reverse zone (BuyReversalSell, SellReversalBuy)
- Second break: Delete zone permanently
- Added check for h4_ZoneReversed flag
- Updated ReverseH4Zone() to:
* Use proper reversal type names (ReversalBuy/ReversalSell)
* Stop M30 monitoring on reversal
* Log old and new zone types
PART 4 - M30 Zone Deletion (VERIFIED):
=======================================
Confirmed: M30 zones already delete correctly on first break
- No reversal logic (as per strategy)
- DeleteM30Zone() called immediately on break
- Implementation matches Strategy.md requirements
Summary of Zone Lifecycles:
============================
H4: Create Break Reverse Break Delete (FIXED)
M30: Create Break Delete (Already correct)
M15: Create Order placed Order closes Delete (FIXED)
All zone deletion logic now fully compliant with Strategy.md
PART 1 - New Input Parameters:
- Added ENUM_LINE_STYLE_SELECT with 5 style options:
* Solid, Dash, Dot, Dash-Dot, Dash-Dot-Dot
- Added InpH4LineStyle (default: Dashed)
- Added InpM30LineStyle (default: Dotted)
- Added InpM15LineStyle (default: Solid)
- Updated all Draw*Zone() functions to use user-selected styles
- H4 reversed zones still force STYLE_SOLID for visibility
PART 2 - CRITICAL STRATEGY FIXES:
Issue #1: WRONG ORDER TYPE (CRITICAL)
---------------------------------------
Problem: Code used OP_BUYSTOP and OP_SELLSTOP
Strategy: Requires OP_BUYLIMIT and OP_SELLLIMIT
This is a PULLBACK/REVERSAL strategy, NOT a breakout strategy!
- Buy Limit = wait for price to pull back DOWN to zone high
- Sell Limit = wait for price to pull back UP to zone low
Fixed Lines 1135-1153:
- Buy orders: OP_BUYLIMIT at M15 zone HIGH
- Sell orders: OP_SELLLIMIT at M15 zone LOW
Issue #2: WRONG STOP LOSS PLACEMENT
------------------------------------
Problem: SL calculated using arbitrary InpStopLossPips
Strategy: SL must be at M15 ZONE BOUNDARY
Fixed:
- Buy orders: SL = m15_ZoneLows[zoneIndex] (zone low)
- Sell orders: SL = m15_ZoneHighs[zoneIndex] (zone high)
- SL now represents technical level, not arbitrary distance
Issue #3: LIMIT Order Distance Validation
------------------------------------------
Problem: Validation logic was for STOP orders
Fixed Lines 1155-1185:
- Buy Limit: entry must be BELOW Bid - minDistance
- Sell Limit: entry must be ABOVE Ask + minDistance
- Opposite direction from STOP orders
VERIFICATION OF CORRECT IMPLEMENTATIONS:
H4 zones: Pattern detection, breakreversedelete lifecycle
H4 zones: NO order placement (bias only)
M30 zones: Start monitoring when price enters H4 zone
M30 zones: Patterns match H4 direction only
M30 zones: Break once and delete (no reversal)
M30 zones: NO order placement (confirmation only)
M15 zones: Start monitoring when price enters M30 zone
M15 zones: Patterns match M30 direction only
M15 zones: ONE order per zone
M15 zones: Order placement ONLY at M15 level
Strategy implementation now FULLY COMPLIANT with Strategy.md
Changes:
1. Rectangle Styling:
- Changed OBJPROP_BACK from true to false for all zones (H4, M30, M15)
- Removed filled rectangles, now draws dashed/dotted/solid outlines only
- Zones render as border-only rectangles with no fill color
2. OrderSend Error 130 Fix (Invalid Stops):
- Added pending order distance validation from current market price
- Buy Stop orders now require entry >= Ask + (StopLevel * 1.5)
- Sell Stop orders now require entry <= Bid - (StopLevel * 1.5)
- Auto-adjusts entry prices if too close to market
- Added TP distance validation (was missing)
- Enhanced error messages with actual vs required distances
Root Cause: Pending orders must be minimum distance from BOTH:
- Current market price (for order placement)
- SL/TP levels (from entry price)
The 1.5x buffer prevents broker rejections on stop level boundaries.
Fixed 8 errors + 2 warnings:
ERRORS FIXED:
1. Added missing 'h4_ZoneBroken' array declaration
2. Added missing 'h4_ZoneReversed' array declaration
3. Removed incorrect 'h4_ZoneIsReversed' array
4. Added initialization for both new arrays in InitializeArrays()
Issue: The code was referencing h4_ZoneBroken and h4_ZoneReversed arrays
that were never declared in the global variables section. The old code
had h4_ZoneIsReversed which was never actually used.
Solution: Declared both arrays as bool[] in the H4 ZONES section and
initialized them to false in InitializeArrays() function.
WARNINGS FIXED:
1. Added return value check for OrderClose() in CloseAllOrders()
2. Added return value check for OrderDelete() in CloseAllOrders()
3. Added error logging when close/delete operations fail
Issue: MQL4 compiler warns when return values from trading functions
are not checked (best practice for error handling).
Solution: Wrapped OrderClose() and OrderDelete() in if statements and
log errors when operations fail.
Status: Should now compile with 0 errors, 0 warnings
