# Uniswap V3 Pricing Functions Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
This document provides comprehensive documentation for the Uniswap V3 pricing functions implemented in the MEV bot project. These functions are critical for calculating price conversions between `sqrtPriceX96` format and standard price representations.
|
||||
|
||||
## Files
|
||||
|
||||
### `pricing.go` - Core Pricing Functions
|
||||
|
||||
This file contains the original implementations of Uniswap V3 pricing functions:
|
||||
|
||||
#### Functions
|
||||
|
||||
1. **SqrtPriceX96ToPrice(sqrtPriceX96 *big.Int) *big.Float**
|
||||
- Converts a `sqrtPriceX96` value to a standard price representation
|
||||
- Formula: `price = (sqrtPriceX96 / 2^96)^2`
|
||||
- Returns a `*big.Float` for precision
|
||||
|
||||
2. **PriceToSqrtPriceX96(price *big.Float) *big.Int**
|
||||
- Converts a standard price to `sqrtPriceX96` format
|
||||
- Formula: `sqrtPriceX96 = sqrt(price) * 2^96`
|
||||
- Returns a `*big.Int`
|
||||
|
||||
3. **TickToSqrtPriceX96(tick int) *big.Int**
|
||||
- Converts a tick value to `sqrtPriceX96`
|
||||
- Formula: `sqrtPriceX96 = 1.0001^(tick/2) * 2^96`
|
||||
|
||||
4. **SqrtPriceX96ToTick(sqrtPriceX96 *big.Int) int**
|
||||
- Converts `sqrtPriceX96` to a tick value
|
||||
- Formula: `tick = 2 * log_1.0001(sqrtPriceX96 / 2^96)`
|
||||
|
||||
5. **GetTickAtSqrtPrice(sqrtPriceX96 *uint256.Int) int**
|
||||
- Calculates the tick for a given `sqrtPriceX96` using uint256
|
||||
- Wrapper around `SqrtPriceX96ToTick`
|
||||
|
||||
6. **GetNextTick(currentTick int, tickSpacing int) int**
|
||||
- Calculates the next initialized tick based on tick spacing
|
||||
|
||||
7. **GetPreviousTick(currentTick int, tickSpacing int) int**
|
||||
- Calculates the previous initialized tick based on tick spacing
|
||||
|
||||
### `cached.go` - Optimized Pricing Functions with Constant Caching
|
||||
|
||||
This file contains optimized versions of the pricing functions that cache expensive constant calculations:
|
||||
|
||||
#### Key Optimization
|
||||
|
||||
The primary optimization is caching the constants `2^96` and `2^192` to avoid recalculating them on every function call.
|
||||
|
||||
#### Functions
|
||||
|
||||
1. **SqrtPriceX96ToPriceCached(sqrtPriceX96 *big.Int) *big.Float**
|
||||
- Optimized version of `SqrtPriceX96ToPrice` using cached constants
|
||||
- Performance improvement: ~24% faster than original
|
||||
|
||||
2. **PriceToSqrtPriceX96Cached(price *big.Float) *big.Int**
|
||||
- Optimized version of `PriceToSqrtPriceX96` using cached constants
|
||||
- Performance improvement: ~12% faster than original
|
||||
|
||||
#### Implementation Details
|
||||
|
||||
- Uses `sync.Once` to ensure constants are initialized only once
|
||||
- Constants `q96` and `q192` are calculated once and reused
|
||||
- Maintains mathematical precision while improving performance
|
||||
|
||||
### `optimized.go` - Alternative Optimization Approaches
|
||||
|
||||
This file contains experimental optimization approaches:
|
||||
|
||||
#### Functions
|
||||
|
||||
1. **SqrtPriceX96ToPriceOptimized(sqrtPriceX96 *big.Int) *big.Float**
|
||||
- Alternative optimization using different mathematical approaches
|
||||
|
||||
2. **PriceToSqrtPriceX96Optimized(price *big.Float) *big.Int**
|
||||
- Alternative optimization using different mathematical approaches
|
||||
|
||||
### `contracts.go` - Uniswap V3 Contract Interface
|
||||
|
||||
This file provides interfaces for interacting with Uniswap V3 pool contracts:
|
||||
|
||||
#### Key Components
|
||||
|
||||
1. **UniswapV3Pool** - Interface for interacting with Uniswap V3 pools
|
||||
2. **PoolState** - Represents the current state of a pool
|
||||
3. **UniswapV3Pricing** - Provides pricing calculations
|
||||
|
||||
#### Functions
|
||||
|
||||
- **GetPoolState** - Fetches current pool state
|
||||
- **GetPrice** - Calculates price for token pairs
|
||||
- **CalculateAmountOut** - Implements concentrated liquidity math for swaps
|
||||
|
||||
## Mathematical Background
|
||||
|
||||
### sqrtPriceX96 Format
|
||||
|
||||
Uniswap V3 uses a fixed-point representation for square root prices:
|
||||
- `sqrtPriceX96 = sqrt(price) * 2^96`
|
||||
- This allows for precise calculations without floating-point errors
|
||||
- Prices are represented as `token1/token0`
|
||||
|
||||
### Tick System
|
||||
|
||||
Uniswap V3 uses a tick system for price ranges:
|
||||
- Ticks are spaced logarithmically
|
||||
- Formula: `tick = log_1.0001(price)`
|
||||
- Each tick represents a price movement of 0.01%
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Benchmark Results
|
||||
|
||||
The optimized functions show significant performance improvements:
|
||||
|
||||
1. **SqrtPriceX96ToPriceCached**: 24% faster (1192 ns/op → 903.8 ns/op)
|
||||
2. **PriceToSqrtPriceX96Cached**: 12% faster (1317 ns/op → 1158 ns/op)
|
||||
|
||||
### Memory Allocations
|
||||
|
||||
Optimized functions reduce memory allocations by 20-33% through constant caching.
|
||||
|
||||
## Usage Examples
|
||||
|
||||
```go
|
||||
// Convert sqrtPriceX96 to price
|
||||
sqrtPrice := big.NewInt(79228162514264337593543950336) // 2^96
|
||||
price := SqrtPriceX96ToPriceCached(sqrtPrice)
|
||||
|
||||
// Convert price to sqrtPriceX96
|
||||
priceFloat := big.NewFloat(1.0)
|
||||
sqrtPriceX96 := PriceToSqrtPriceX96Cached(priceFloat)
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Each function is thoroughly tested with:
|
||||
- Unit tests in `*_test.go` files
|
||||
- Round-trip conversion accuracy tests
|
||||
- Property-based testing for mathematical correctness
|
||||
- Benchmark tests for performance verification
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. Use cached versions for repeated calculations
|
||||
2. Always validate input parameters
|
||||
3. Handle big.Int overflow conditions
|
||||
4. Use appropriate precision for financial calculations
|
||||
5. Profile performance in the context of your application
