# Dashboard Unicode Fix & Account Balance Enhancement Summary
|
||||
|
||||
## Issues Fixed
|
||||
|
||||
### 1. Unicode Encoding Errors
|
||||
**Problem**: Windows console (cp1252) couldn't display Unicode emoji characters in logging output, causing `UnicodeEncodeError`.
|
||||
|
||||
**Files Fixed**:
|
||||
- `core/data_provider.py`
|
||||
- `web/scalping_dashboard.py`
|
||||
|
||||
**Changes Made**:
|
||||
- Replaced `✅` with `OK:`
|
||||
- Replaced `❌` with `FAIL:`
|
||||
- Replaced `⏭️` with `SKIP:`
|
||||
- Replaced `✗` with `FAIL:`
|
||||
|
||||
### 2. Missing Import Error
|
||||
**Problem**: `NameError: name 'deque' is not defined` in dashboard initialization.
|
||||
|
||||
**Fix**: Added missing import `from collections import deque` to `web/scalping_dashboard.py`.
|
||||
|
||||
### 3. Syntax/Indentation Errors
|
||||
**Problem**: Indentation issues in the dashboard file causing syntax errors.
|
||||
|
||||
**Fix**: Corrected indentation in the universal data format validation section.
|
||||
|
||||

## Technical Details
|
||||
|
||||
### Account Balance Calculation
|
||||
```python
|
||||
# Calculate balance change from starting balance
|
||||
balance_change = current_balance - starting_balance
|
||||
balance_change_pct = (balance_change / starting_balance) * 100
|
||||
account_details = f"Change: ${balance_change:+.2f} ({balance_change_pct:+.1f}%)"
|
||||
```
|
||||
|
||||
### Position Display Logic
|
||||
```python
|
||||
if side == 'LONG':
|
||||
unrealized_pnl = (current_price - entry_price) * size
|
||||
color_class = "text-success" # Green
|
||||
side_display = "[LONG]"
|
||||
else: # SHORT
|
||||
unrealized_pnl = (entry_price - current_price) * size
|
||||
color_class = "text-danger" # Red
|
||||
side_display = "[SHORT]"
|
||||
```
|
||||
|
||||
## Dashboard Layout Updates
|
||||
|
||||
### Account Section
|
||||
```html
|
||||
<div class="col-md-3 text-center">
|
||||
<h4 id="current-balance" class="text-success">$100.00</h4>
|
||||
<p class="text-white">Current Balance</p>
|
||||
<small id="account-details" class="text-muted">Change: $0.00 (0.0%)</small>
|
||||
</div>
|
||||
```
|
||||
|
||||
## Testing Results

||||
|
||||
