```
## Maker/Taker Fees (v0.4.6)
Split fees by liquidity role for more realistic paper trading and backtesting:
```python
from horizon import Engine
# Flat fee (backward compatible)
engine = Engine(paper_fee_rate=0.001)
# Split maker/taker fees
engine = Engine(
paper_maker_fee_rate=0.0002, # 2 bps for makers
paper_taker_fee_rate=0.002, # 20 bps for takers
)
```
Each `Fill` now includes an `is_maker` field (`True`/`False`) indicating whether the order was a maker or taker. Works with both the paper exchange and BookSim (L2 backtesting).
## Chainlink On-Chain Oracle Feed (v0.4.7)
Read prices directly from Chainlink aggregator contracts on any EVM chain:
```python
import horizon as hz
hz.run(
feeds={
"eth_usd": hz.ChainlinkFeed(
contract_address="0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419",
rpc_url="https://eth.llamarpc.com",
),
},
...
)
```
Common contract addresses (Ethereum mainnet):
- ETH/USD: `0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419`
- BTC/USD: `0xF4030086522a5bEEa4988F8cA5B36dbC97BeE88c`
- LINK/USD: `0x2c1d072e956AFFC0D435Cb7AC38EF18d24d9127c`
Works with Ethereum, Arbitrum, Polygon, BSC — just change `rpc_url`.
## New Data Feeds (v0.4.5)
Five new feed types for cross-market signals beyond crypto:
- **PredictItFeed** - PredictIt market prices (lastTradePrice, bestBuyYesCost, bestSellYesCost)
- **ManifoldFeed** - Manifold Markets probability and volume
- **ESPNFeed** - Live sports scores (home/away score, period, game status)
- **NWSFeed** - National Weather Service forecasts (temperature, wind, precip) and alerts
- **RESTJsonPathFeed** - Flexible JSON path extraction from any REST API
Setup in `hz.run()`:
```python
import horizon as hz
hz.run(
feeds={
"pi": hz.PredictItFeed(market_id=7456, contract_id=28562),
"manifold": hz.ManifoldFeed("will-btc-hit-100k-by-2026"),
"nba": hz.ESPNFeed("basketball", "nba"),
"weather": hz.NWSFeed(state="FL", mode="alerts"),
"custom": hz.RESTJsonPathFeed(
url="https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd",
price_path="bitcoin.usd",
),
},
...
)
```
## Execution Algorithms (v0.4.4)
Three execution algorithms for splitting large orders with minimal market impact:
- **TWAP** (`hz.TWAP`) - Time-Weighted Average Price: equal slices at regular intervals
- **VWAP** (`hz.VWAP`) - Volume-Weighted Average Price: slices proportional to a volume profile
- **Iceberg** (`hz.Iceberg`) - Shows only a small visible portion, auto-replenishes on fill
All use the same interface: `algo.start(request)`, `algo.on_tick(price, time)`, `algo.is_complete`, `algo.total_filled`.
## Signal Combiner + Market Maker (v0.4.8)
Compose multi-signal strategies with automatic pipeline chaining:
```python
hz.run(
pipeline=[
hz.signal_combiner([
hz.price_signal("book", weight=0.5),
hz.imbalance_signal("book", levels=5, weight=0.3),
hz.flow_signal("book", window=30, weight=0.2),
]),
hz.market_maker(feed_name="book", gamma=0.5, size=5.0),
],
...
)
```
Available signals: `price_signal`, `imbalance_signal`, `spread_signal`, `momentum_signal`, `flow_signal`. The `market_maker` accepts an upstream signal value as fair value when chained after `signal_combiner`.
## Pipeline Features (v0.4.4)
The Horizon SDK also includes advanced pipeline components for automated strategies:
- **Markov Regime Detection** (`markov_regime`) - Rust HMM (Hidden Markov Model) for real-time regime classification. Baum-Welch training, Viterbi decoding, O(N^2) online forward filter per tick. Supports pre-trained models or auto-train with warmup.
- **Regime Detection** (`regime_signal`) - volatility/trend regime classification (0=calm, 1=volatile)
- **Feed Guard** (`feed_guard`) - auto-activates kill switch when feeds go stale
- **Inventory Skew** (`inventory_skewer`) - shifts quotes to reduce position risk
- **Adaptive Spread** (`adaptive_spread`) - dynamically widens/narrows spread based on fill rate, volatility, and order imbalance
- **Execution Tracker** (`execution_tracker`) - monitors fill rate, slippage, and adverse selection
- **Multi-Strategy** - run different pipelines per market via dict config
- **Cross-Market Hedging** (`cross_hedger`) - generates hedge quotes when portfolio delta exceeds threshold
### Quantitative Analytics (v0.4.4)
- **Information Theory** - Shannon entropy, joint entropy, KL divergence, mutual information, transfer entropy
- **Microstructure** - Kyle's lambda, Amihud ratio, Roll spread, effective/realized spread, LOB imbalance, microprice
- **Risk Analytics** - Cornish-Fisher VaR/CVaR, prediction Greeks (delta, gamma, theta, vega for binary markets)
- **Signal Analysis** - information coefficient (Spearman), signal half-life, Hurst exponent, variance ratio test
- **Statistical Testing** - deflated Sharpe ratio, Bonferroni correction, Benjamini-Hochberg FDR control
- **Streaming Detectors** - VPIN toxic flow, CUSUM change-point, order flow imbalance (OFI) tracker
- **Pipeline Functions** - `toxic_flow()`, `microstructure()`, `change_detector()` for real-time analytics in `hz.run()`
- **Stress Testing** - Monte Carlo under adverse scenarios (correlation spike, all-resolve-no, liquidity shock, tail risk)
- **CPCV** - Combinatorial Purged Cross-Validation with Probability of Backtest Overfitting (PBO)
### Backtesting (v0.4.4)
- **L2 Book Simulation** - replay historical orderbook snapshots with `book_data` parameter
- **Fill Models** - `deterministic`, `probabilistic` (queue position), `glft` (Gueant-Lehalle-Fernandez-Tapia)
- **Market Impact** - temporary + permanent price impact simulation
- **Latency Simulation** - configurable order-to-fill delay in ticks
- **Calibration Analytics** - Rust-powered calibration curve, Brier score, log-loss, ECE
- **Edge Decay** - measure how edge decays vs time-to-resolution
- **Walk-Forward Optimization** - rolling/expanding window parameter optimization with purge gap
These are Python pipeline functions used with `hz.run()` and `hz.backtest()`. See the SDK documentation for usage.
## New Features (v0.4.16)
### AFML (Advances in Financial Machine Learning)
Rust-native implementations of Lopez de Prado's research:
- **Information-Driven Bars** (`hz.dollar_bars`, `hz.volume_bars`, `hz.tick_bars`, `hz.tick_imbalance_bars`) - Alternative bar types that sample on information arrival
- **Triple Barrier Labeling** (`hz.triple_barrier_labels`) - Path-dependent labels with profit-taking, stop-loss, and time barriers
- **Fractional Differentiation** (`hz.frac_diff_weights`, `hz.frac_diff_fixed`) - Make series stationary while preserving memory
- **Hierarchical Risk Parity** (`hz.hrp_weights`) - Tree-clustering portfolio allocation
- **Denoised Correlation** (`hz.marchenko_pastur_bounds`, `hz.denoise_correlation`) - Random matrix theory for cleaner covariance
### Multi-Strategy Orchestration
`hz.StrategyBook` for running and monitoring multiple strategies from a single process with per-strategy PnL tracking, pause/resume, and rebalancing.
### Alpha Research Tools
- `hz.feature_importance` - MDI/MDA feature importance via random forests
- `hz.compute_bet_sizing` - Probability-to-size via linear/sigmoid/discrete scaling
### Tier-Based Feature Gating

## New Features (v0.4.14)
### Tearsheet Analytics

### Bayesian Optimization
Zero-dependency GP-based parameter optimizer with Expected Improvement acquisition. Finds optimal strategy parameters efficiently.
### Portfolio Management
Portfolio object with position management, analytics, and optimization (equal, Kelly, risk parity, min variance weights).
### Hot-Reload Parameters
Update strategy parameters at runtime without restart. Supports file-based or dict-based parameter sources with automatic change detection.
### Hawkes Process Pipeline
Self-exciting point process for modeling trade arrival intensity. Triggers on fills and large price jumps. Per-market isolation.
### Ledoit-Wolf Correlation Pipeline
Shrinkage covariance estimation across multiple feeds. Optimal shrinkage intensity computed via Ledoit-Wolf formula.
## Output format
All commands return JSON. On success you get the data directly. On error you get `{"error": "message"}`.
## Important notes
- The `quote` command submits **real orders** (or paper orders depending on config). Always confirm with the user before submitting.
- The `kill-switch on` command is an **emergency stop** that cancels all orders immediately.
- Prices are **probabilities** between 0 and 1 (e.g., 0.65 = 65% implied probability).
- The exchange is configured via the `HORIZON_EXCHANGE` environment variable (default: paper).
