# Compilation Fixes Applied
## Issues Fixed
### 1. Reserved Keyword Error - "protected"
**Problem:**
```
'protected' is a reserved keyword in MQL5 and cannot be used as a variable name
```
**Location:** [ERMT_PME_1.2.mq5:985](ERMT_PME_1.2.mq5#L985)
**Original Code:**
```mql5
double protected, peak, retracement;
g_profit_max.GetProtectionStatus(ticket, protected, peak, retracement);
if(protected > 0)
{
locked_positions++;
total_locked_profit += protected;
}
```
**Fixed Code:**
```mql5
double protected_profit, peak_profit, retracement_pct;
g_profit_max.GetProtectionStatus(ticket, protected_profit, peak_profit, retracement_pct);
if(protected_profit > 0)
{
locked_positions++;
total_locked_profit += protected_profit;
}
```
**Status:** ✅ Fixed
---
### 2. Type Conversion Warning
**Problem:**
```
possible loss of data due to type conversion from 'long' to 'int'
```
**Location:** [PositionManager_PME_Complete.mqh:562](Modules_PME/PositionManager_PME_Complete.mqh#L562)
**Original Code:**
```mql5
long deal_reason = HistoryDealGetInteger(deal_ticket, DEAL_REASON);
switch(deal_reason)
```
**Fixed Code:**
```mql5
long deal_reason = HistoryDealGetInteger(deal_ticket, DEAL_REASON);
switch((int)deal_reason) // Explicit cast to int
```
**Status:** ✅ Fixed

## Next Steps
1. **Recompile EA:**
```
- Open MetaEditor
- Compile ProfitMaximizer_PME.mqh
- Compile PositionManager_PME_Complete.mqh
- Compile ERMT_PME_1.2.mq5
- Verify: 0 errors
```
2. **Test on Chart:**
```
- Attach EA to chart
- Check initialization logs
- Verify dashboard displays
- Test with demo positions
```
3. **Monitor for:**
- Phase transitions
- Lock applications
- Dashboard updates
- Log messages
