# Compilation Errors and Warnings Fix Summary
|
||
|
|
|
||
|
|
## Date: 2025-11-14
|
||
|
|
|
||
|
|
## Problem Statement
|
||
|
|
The v3.2 production files had compilation errors and warnings preventing successful build:
|
||
|
|
- **6 errors** per file (undeclared identifier errors)
|
||
|
|
- **10-12 warnings** per file (variable hiding warnings)
|
||
|
|
|
||
|
|
## Root Cause Analysis
|
||
|
|
|
||
|
|
### Critical Errors
|
||
|
|
The EA was refactored to support both multi-symbol and single-symbol trading modes:
|
||
|
|
- **Multi-symbol mode**: Uses `SymbolData` struct with per-symbol `lastBuyTime` and `lastSellTime`
|
||
|
|
- **Single-symbol mode**: Legacy mode that needs global `lastBuyTime` and `lastSellTime` variables
|
||
|
|
|
||
|
|
The global variables were removed during refactoring but were still referenced in the `CheckEntrySignals()` function used by single-symbol mode, causing undeclared identifier errors.
|
||
|
|
|
||
|
|
### Warnings
|
||
|
|
Local variable declarations in several functions were shadowing global variables, causing "variable hiding" warnings:
|
||
|
|
- Indicator buffer arrays (fastMA, slowMA, bbUpper, bbMiddle, bbLower, macdMain, macdSignal)
|
||
|
|
- Symbol properties (pipSize, minLot, point)
|
||
|
|
|
||
|
|
## Solutions Applied
|
||
|
|
|
||
|
|
### ForexTrader_v3.2_MultiStrategy_Production.mq5
|
||
|
|
|
||
|
|
#### 1. Added Missing Global Variables (Lines 257-259)
|
||
|
|
```mql5
|
||
|
|
// Trading state for single-symbol mode (legacy)
|
||
|
|
datetime lastBuyTime = 0;
|
||
|
|
datetime lastSellTime = 0;
|
||
|
|
```
|
||
|
|
|
||
|
|
#### 2. Renamed Local Variables to Avoid Shadowing
|
||
|
|
|
||
|
|
**In CheckSymbolEntrySignals() function:**
|
||
|
|
- `fastMA[]` → `symFastMA[]`
|
||
|
|
- `slowMA[]` → `symSlowMA[]`
|
||
|
|
- `bbUpper[]` → `symBbUpper[]`
|
||
|
|
- `bbMiddle[]` → `symBbMiddle[]`
|
||
|
|
- `bbLower[]` → `symBbLower[]`
|
||
|
|
- `macdMain[]` → `symMacdMain[]`
|
||
|
|
- `macdSignal[]` → `symMacdSignal[]`
|
||
|
|
- `atrBuf[]` → `symAtrBuf[]`
|
||
|
|
- `adxBuf[]` → `symAdxBuf[]`
|
||
|
|
- `rsiBuf[]` → `symRsiBuf[]`
|
||
|
|
|
||
|
|
All references within the function updated accordingly (10+ occurrences each).
|
||
|
|
|
||
|
|
**In ManagePositions() function:**
|
||
|
|
- `pipSize` → `symPipSize` (line 2103)
|
||
|
|
- `minLot` → `symMinLot` (line 2129)
|
||
|
|
|
||
|
|
**In GetSymbolPipSize() function:**
|
||
|
|
- `point` → `symPoint` (line 2221)
|
||
|
|
- Fixed return statement to use `symPoint` instead of global `point`
|
||
|
|
|
||
|
|
### ForexTrader_v3.2_Scalper_Production.mq5
|
||
|
|
|
||
|
|
Applied identical fixes as MultiStrategy version:
|
||
|
|
|
||
|
|
#### 1. Added Missing Global Variables (Lines 268-270)
|
||
|
|
```mql5
|
||
|
|
// Trading state for single-symbol mode (legacy)
|
||
|
|
datetime lastBuyTime = 0;
|
||
|
|
datetime lastSellTime = 0;
|
||
|
|
```
|
||
|
|
|
||
|
|
#### 2. Renamed Local Variables
|
||
|
|
|
||
|
|
**In CheckSymbolEntrySignals() function:**
|
||
|
|
- All indicator buffer arrays renamed with `sym` prefix
|
||
|
|
- All references updated (10+ occurrences each)
|
||
|
|
|
||
|
|
**In ManagePositions() function:**
|
||
|
|
- `pipSize` → `symPipSize` (line 2154)
|
||
|
|
- `minLot` → `symMinLot` (line 2176)
|
||
|
|
|
||
|
|
**In GetSymbolPipSize() function:**
|
||
|
|
- `point` → `symPoint` (line 2268)
|
||
|
|
|
||
|
|
**In CheckMomentum() function:**
|
||
|
|
- Parameter `pipSize` → `symbolPipSize` (line 2280)
|
||
|
|
|
||
|
|
**In CheckBreakout() function:**
|
||
|
|
- Parameter `pipSize` → `symbolPipSize` (line 2306)

## Testing Recommendations
|
||
|
|
1. Compile both files in MetaTrader 5 Editor to verify 0 errors/warnings
