​
Overview

Get detailed asymmetric funding rate information for a specific trading market. Strike Protocol’s innovative funding system allows long and short positions to have different funding rates based on open interest imbalance, creating more efficient price discovery and better trading opportunities.
This endpoint does NOT require authentication and provides real-time funding rate data for all users.

​

​
Asymmetric Funding System

​
How It Works

Strike Protocol implements a unique asymmetric funding system that differs from traditional perpetual exchanges:

​
Traditional Funding

  • Single rate: Same funding rate for both long and short positions
  • Zero-sum: One side always pays, the other always receives
  • Fixed relationship: If longs pay +0.01%, shorts receive -0.01%

​
Asymmetric Funding

  • Different rates: Long and short positions can have different rates
  • Independent calculation: Rates calculated separately based on OI imbalance
  • More efficient: Better reflects actual market supply/demand dynamics

​
Rate Calculation

Funding rates are calculated based on open interest imbalance:

​
Long-Heavy Market

When long open interest > short open interest: 
Long Rate: Positive (longs pay funding)
Short Rate: Less positive or negative (shorts may receive funding)

​
Short-Heavy Market

When short open interest > long open interest: 
Long Rate: Less positive or negative (longs may receive funding)
Short Rate: Positive (shorts pay funding)

​
Balanced Market

When open interest is roughly balanced: 
Long Rate: Near zero
Short Rate: Near zero

​
Funding Application

​
Timing

  • Application frequency: Every hour
  • Position age requirement: Positions must be 8+ hours old
  • Automatic: No manual action required

​
Calculation

Hourly Funding Payment = Position Size × Funding Rate
Example:
  • Position size: $10,000
  • Long rate: 0.000125 (0.0125%)
  • Hourly payment: 10,000×0.000125=10,000 × 0.000125 = 1.25 paid

​
Impact on PnL

  • Paying funding: Reduces unrealized PnL
  • Receiving funding: Increases unrealized PnL
  • Accumulated over time: Significant impact on long-held positions

Consider funding rates when planning longer-term positions. A position receiving 10%+ annually in funding can significantly boost returns, while paying high funding rates can erode profits.
Funding rates can change rapidly based on market conditions. Don’t rely on current rates persisting for extended periods when planning carry trades.
