Issue: ROE% Calculation Mismatch with aster.dex

Description

There's a significant discrepancy in how Return on Equity (ROE%) is calculated between lik hunter and aster.dex for the same position. The ROE% in lik hunter is much lower than what's shown in aster.dex.

Position Details

• Symbol: BNBUSDT
• Position Size: 0.12 BNB
• Entry Price: 1,113.75 USDT
• Mark Price: 1,158.474 USDT
• Leverage: 25x
• Position Value: ~139.02 USDT (0.12 * 1,158.474)

Observed Values

Platform	PNL (USDT)	ROE%	Calculation Base
aster.dex	+5.37	96.57%	Based on margin (5.56 USDT)
lik hunter	~5.37	~3.86%	Based on position value

Analysis

1. Dollar Amounts:

   • Both platforms show approximately the same PNL in USDT (~5.37 USDT)

2. Percentage Calculation:

   • aster.dex (96.57%):

     • Margin = Position Value / Leverage = 139.02 / 25 = 5.56 USDT
     • ROE = (5.37 / 5.56) * 100 ≈ 96.57%
     • This is the industry standard for leveraged trading (PNL/margin)

   • lik hunter (~3.86%):

     • Appears to be calculating as (5.37 / 139.02) * 100 ≈ 3.86%
     • This is incorrect as it uses position value instead of margin

Expected Behavior

The ROE% in lik hunter should match aster.dex's calculation:

ROE% = (Unrealized PNL / Margin) * 100 = (5.37 / 5.56) * 100 ≈ 96.57%

Impact

• Misleading ROE% could lead to incorrect risk assessment
• Inconsistent with standard trading platform behavior
• May cause confusion in performance evaluation

Request

1. Update the ROE% calculation to use margin as the base (like aster.dex)
2. Consider renaming to "ROE%" to be explicit about the calculation
3. Add a tooltip explaining the calculation method
4. Add tests to ensure consistency with exchange calculations

Additional Context

• The dollar PNL amounts match between platforms
• The issue is specifically with the percentage calculation
• The correct calculation should use margin (position value / leverage) as the base
