App Formulas

Formulas at stake when interacting with app.angle.money

Borrow
Loan To Value - LTV
This is the value of the vault debt compared to that of the collateral.
LTV=debtcollateral\texttt{LTV} = \frac{\texttt{debt}}{\texttt{collateral}}LTV=collateraldebt​
Health Factor - HF
This is an indication of the health of the vault. Below 1, vaults can get liquidated.
HF=1LTV×max. LTV\texttt{HF} = \frac{1}{\texttt{LTV}} \times {\texttt{max. LTV}}HF=LTV1​×max. LTV
Perpetuals
Margin
The margin displayed on your position is computed net of opening fees, i.e.
margin=initial margin - position size×opening fees\texttt{margin} = \texttt{initial margin - position size} \times \texttt{opening fees}margin=initial margin - position size×opening fees
Leverage
In Angle, leverage is computed as:
​leverage=(margin + position Size)margin\texttt{leverage} = \frac{\texttt{(margin + position Size)}}{\texttt{margin}}leverage=margin(margin + position Size)​
​
Example
Margin: 10,000 DAI
Position size: 100,000 DAI
​leverage=1+101=11\texttt{leverage} = \frac{1 + 10}{1} = 11leverage=11+10​=11
​
Cash-out Amount
The Cash-out amount represents the amount you should receive in your wallet after closing the perpetual:
​cash-out amount=margin±gross PnL - closing fee\texttt{cash-out amount} = \texttt{margin} \pm \texttt{gross PnL - closing fee}cash-out amount=margin±gross PnL - closing fee
​
With grossPnL=position size×(1−initialPricecurrentPrice)\texttt{grossPnL} = \texttt{position size}\times(1-\frac{\texttt{initialPrice}}{\texttt{currentPrice}})grossPnL=position size×(1−currentPriceinitialPrice​)
​
Profit & Loss (or PnL)
The PnL displayed on the app represents the gain or loss you would make if closing the position. It is computed net of fees.
​PnL=cash-out amount - initial margin\texttt{PnL} = \texttt{cash-out amount - initial margin}PnL=cash-out amount - initial margin
 PnL=gross PnL - closing fee\texttt{PnL} = \texttt{gross PnL - closing fee}PnL=gross PnL - closing fee
​
Maintenance Margins
DAI: 0.625%
USDC: 0.625%
FRAX: 0.625%
ETH: 6.25%
Margin Ratio Formula In Angle, the margin ratio is computed as:
margin ratio=cash out amountposition size\texttt{margin ratio} = \frac{\texttt{cash out amount}}{\texttt{position size}}margin ratio=position sizecash out amount​
Staking
Standard Liquidity Providers
The Staking page of the app lists all the opportunities for agEUR holders. It also contains the logic linked to Standard Liquidity providers of the protocol.
Slippage
Users may face a slippage when they exit from their SLP position and sell their sanTokens. It depends on specific parameters for the collateral of interest and on the collateral ratio of the stablecoin in the Core module. This is put in place to incentivize them to stay in the protocol while it gets re-collateralized.
amnt received=amnt withdrawn×(1−slippage)\texttt{amnt received} = \texttt{amnt withdrawn} \times{(1 - \texttt{slippage})}amnt received=amnt withdrawn×(1−slippage)
The current slippage for SLP can be consulted in the analytics by selecting a pool and looking at Slippage in the Fee Info > SLP section.
Slippage on Fees for SLP
When the protocol gets close to be under-collateralized, it progressively keeps a bigger portion of the fees usually going to SLPs to grow the suplus and be able to pay back stable holders. Note that this doesn't impact the initial deposits of SLPs nor the fees earned up until the start of the slippage fee.
fees received=fees to SLPs×(1−slippage fee)\texttt{fees received} = \texttt{fees to SLPs} \times{(1-\texttt{slippage fee})}fees received=fees to SLPs×(1−slippage fee)
The current slippage fee for SLP can be consulted in the analytics by selecting a pool and looking at SlippageFee in the Fee Info > SLP section.
Global parameters
If you want to know the current protocol parameters in place, you can have a look at the analytics at analytics.angle.money or directly in the SDK.
