5.6.2: Perpetual Contracts – The Most Popular Derivative

What are Perpetuals?

Perpetual contracts (perpetuals) are derivative instruments that track the price of an underlying asset without an expiry date. They are the most popular DeFi derivative.

Funding Rate Mechanics:

The funding rate ensures the perpetual price stays close to the spot price.

text
Funding Rate Formula:

Funding Rate = (Mark_Price - Index_Price) / Index_Price + Interest_Rate

Components:
1. Premium: Difference between mark and index price
2. Interest: Base rate (usually 0.01%)

If Mark_Price > Index_Price (Bullish):
- Longs pay shorts
- Incentivizes shorts to enter
- Pushes price down

If Mark_Price < Index_Price (Bearish):
- Shorts pay longs
- Incentivizes longs to enter
- Pushes price up

Example Calculation:

Index Price: $3,000
Mark Price: $3,030
Premium: 1% (30/3000)
Interest: 0.01% (0.0001)

Funding Rate = 0.01 + 0.0001 = 0.0101 (1.01%)

Payment (Long Position, 1 ETH):
- 1.01% × 1 ETH = 0.0101 ETH paid to shorts
- 8-hour payment cycle

Funding Rate History:
- Positive: Longs pay shorts (bullish)
- Negative: Shorts pay longs (bearish)
- Typically 0.01-0.10% per 8 hours

Leverage and Margin:

text
Leverage Mechanics:

Position Size = Margin × Leverage

Example:
- Margin: 1 ETH ($3,000)
- Leverage: 10x
- Position Size: 10 ETH ($30,000)

Price Change Impact:
- 1% Price Increase: 10% Profit
- 1% Price Decrease: 10% Loss
- 10% Price Decrease: 100% Loss (Liquidation)

Margin Requirements:
- Initial Margin: 1/leverage
- Maintenance Margin: 0.5-1%
- Liquidation: When margin falls below maintenance

Liquidation Price:
Long Position:
Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance/2)

Short Position:
Liquidation Price = Entry Price × (1 + 1/Leverage - Maintenance/2)

Example (Long, 10x Leverage):
Entry: $3,000
Liquidation: $3,000 × (1 - 0.10 + 0.005) = $2,715

5.6.3: Options – The Right, Not the Obligation

Option Basics:

Options give the holder the right, but not the obligation, to buy or sell an asset at a predetermined price before a specific date.

Option Pricing – The Black-Scholes Model:

The Black-Scholes model is the standard for pricing European options.

text
Black-Scholes Formula:

C = S × N(d₁) - K × e^(-rt) × N(d₂)

Where:
C = Call Option Price
S = Current Asset Price
K = Strike Price
r = Risk-Free Rate
t = Time to Expiry
σ = Volatility

d₁ = (ln(S/K) + (r + σ²/2) × t) / (σ × √t)
d₂ = d₁ - σ × √t

Put Option Price:
P = K × e^(-rt) × N(-d₂) - S × N(-d₁)

Example (ETH Option):
S = $3,000
K = $3,200
t = 30 days (0.082 years)
σ = 80%
r = 5%

d₁ = (ln(3000/3200) + (0.05 + 0.64/2) × 0.082) / (0.8 × √0.082)
d₁ = (-0.0645 + 0.0305) / 0.229
d₁ = -0.148

d₂ = -0.148 - 0.229 = -0.377

N(d₁) = 0.441
N(d₂) = 0.353

Call Price = 3000 × 0.441 - 3200 × e^(-0.0041) × 0.353
Call Price = 1323 - 1126 = $197

Option Strategies:

 
 
Strategy Setup Direction Risk/Reward
Long Call Buy Call Bullish Limited loss (premium)
Long Put Buy Put Bearish Limited loss (premium)
Covered Call Hold asset + Sell Call Neutral Limited upside
Protective Put Hold asset + Buy Put Bullish Protects downside
Straddle Buy Call + Buy Put Volatile High cost
Spread Buy + Sell Options Various Limited risk/reward

5.6.6: Derivative Risks – Complete Analysis

Risk Matrix:

 
 
Risk Severity Description Mitigation
Liquidation Critical Position liquidated Monitor margin
Leverage Risk High Amplified losses Use lower leverage
Funding Rate Medium Additional costs Monitor rates
Oracle Risk High Wrong price data Use multiple oracles
Smart Contract High Protocol bugs Audits, insurance
Slippage Low Price impact Use limit orders
Counterparty Low Protocol failure Diversify
Liquidity Medium Cannot exit Check depth

Liquidation Example:

text
Liquidation Scenario:

Position: Long 1 BTC
Entry Price: $60,000
Leverage: 10x
Margin: 0.1 BTC ($6,000)
Position Size: 1 BTC ($60,000)
Liquidation Price: $54,000

Price Drops to $54,000:
- Loss: $6,000 (100% of margin)
- Position liquidated
- User loses $6,000

If Price Recovers:
- No recovery
- Position gone
- User loses all margin

Prevention:
- Use lower leverage (2-5x)
- Add margin
- Set stop-losses
- Monitor regularly

1. Perpetual Contract Math

text
Perpetual Contract Value:

P = S × (1 + r × t) + f

Where:
P = Perpetual Price
S = Spot Price
r = Funding Rate
t = Time to Next Funding
f = Premium/Discount

Mark Price Calculation:
Mark Price = Index Price + (Premium × K)

Where K = 0.01 (smoothing factor)

Liquidation Calculation:
Liquidation Price = Entry Price × (1 - 1/Leverage + Maintenance/2)

2. Option Greeks

text
Option Greeks:

1. Delta (Δ): Rate of change of option price with underlying
   Δ = N(d₁) for calls
   Δ = N(d₁) - 1 for puts

2. Gamma (Γ): Rate of change of delta
   Γ = N'(d₁) / (S × σ × √t)

3. Vega (V): Sensitivity to volatility
   V = S × N'(d₁) × √t

4. Theta (Θ): Time decay
   Θ = -(S × N'(d₁) × σ)/(2√t) - r × K × e^(-rt) × N(d₂)

5. Rho (ρ): Sensitivity to interest rate
   ρ = K × t × e^(-rt) × N(d₂)
