Technical Details

Account Balance Calculation

# 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

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

<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>
