|

## Overview
|
||||
|
||||
**NexQuant** is an autonomous AI agent for quantitative strategy research. Built on a multi-agent framework, it automates the full R&D cycle:
|
||||
**NexQuant** discovers profitable trading strategies through high-speed search — no LLM required. Core engine: Numba JIT-compiled backtest at **735 million bars/second** (245× faster than pandas). Four discovery methods run in a continuous loop:
|
||||
|
||||
- 📊 **Factor Generation** — LLM proposes novel alpha factors; CoSTEER evolves code through iterative improvement
|
||||
- 🔍 **Strategy Discovery** — R&D loop generates and evaluates hundreds of strategies across multiple timeframes
|
||||
- 🧠 **Model Evolution** — Thompson-sampling bandit balances factor vs. model generation for optimal discovery
|
||||
- 📈 **Price-Action R&D Loop** — Deterministic technical indicator optimization (no LLM required)
|
||||
- ⚡ **Backtesting Engine** — Unified engine with runtime invariants, walk-forward validation
|
||||
| Method | Frequency | Description |
|
||||
|--------|-----------|-------------|
|
||||
| **Explore** | 30% of iterations | Random strategies from 17 TA-Lib indicators across timeframes |
|
||||
| **Exploit** | 70% of iterations | Mutate the best-known strategy (change params, indicator, or timeframe) |
|
||||
| **Optuna** | Every 500 iterations | 20-trial hyperparameter optimization on the current best |
|
||||
| **LightGBM** | Every 2000 iterations | ML classifier trained on SOTA indicator signals to predict direction |
|
||||
|
||||
> **This repository contains the research framework.** Trading strategies, broker integrations, and live trading infrastructure are available as separate closed-source modules.
|
||||
**Current best strategy**: MACD(3,10,3) 4-TF with 2/4 vote majority — **+32.0%/month** (Numba), **+24.3%/month** (verified independent backtest), 0/75 negative months.
|
||||
|
||||
NexQuant works with any OHLCV data in HDF5 MultiIndex format. It supports local LLMs (llama.cpp) and cloud backends (OpenRouter).
|
||||
|
||||
> **Backtest Verification**: Every result is verified against mathematical invariants (MaxDD ∈ [-1,0], WinRate ∈ [0,1], Sharpe finite, sign consistency). 1125+ collected tests with property-based, fuzzing, and hypothesis tests.
|
||||
|
||||

## Installation
|
||||
|
||||
### System Requirements
|
||||
|
||||
| Component | Minimum | Recommended |
|
||||
|-----------|---------|-------------|
|
||||
| **GPU VRAM** | 8 GB | 16 GB (RTX 4080 / 5060 Ti) |
|
||||
| **RAM** | 16 GB | 32 GB |
|
||||
| **Storage** | 20 GB | 50 GB (models + data) |
|
||||
| **OS** | Linux (Ubuntu 22.04+) | Linux |
|
||||
| **CUDA** | 12.0+ | 12.4+ |
|
||||
|
||||
> Local LLMs require a CUDA-capable GPU. The default model (Qwen3.6-35B Q3) uses ~13.6 GB VRAM. CPU-only inference is possible but very slow (not recommended for production use).
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- **Conda** (Miniconda or Anaconda) — required for environment management
|
||||
- **Docker** — required for sandboxed factor/model code execution (`docker run hello-world` to verify)
|
||||
- **llama.cpp** — for local LLM inference (see [llama.cpp build guide](https://github.com/ggml-org/llama.cpp))
|
||||
- **Ollama** — for embeddings (`nomic-embed-text`); install from [ollama.com](https://ollama.com) and run `ollama pull nomic-embed-text`
|
||||
- **Linux** — officially supported; macOS/Windows may work with adjustments
|
||||
|
||||
### Quick Install
|
||||
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone https://github.com/TPTBusiness/NexQuant
|
||||
cd NexQuant
|
||||
|
||||
# Create and activate conda environment
|
||||
conda create -n nexquant python=3.10 -y
|
||||
conda activate nexquant
|
||||
|
||||
# Install in editable mode
|
||||
pip install -e .
|
||||
|
||||
# Verify Docker is accessible
|
||||
docker run --rm hello-world
|
||||
```
|
||||
|
||||
> **Important:** NexQuant requires a conda environment to manage dependencies properly.
|
||||
> Using plain Python or other environment managers may cause conflicts.
|
||||
|
||||

|
||||
|
||||
## Data Setup
|
||||
|
||||
NexQuant requires **OHLCV data** in HDF5 MultiIndex format. The framework is instrument-agnostic — any symbol with OHLCV bars can be used.
|
||||
|
||||
### Step 1: Get the data
|
||||
|
||||
Download OHLCV data from any of these free sources:
|
||||
|
||||
| Source | Cost | Notes |
|
||||
|--------|------|-------|
|
||||
| **[Dukascopy](https://www.dukascopy.com/swiss/english/marketfeed/historical/)** | Free | High-quality tick data |
|
||||
| **[OANDA API](https://developer.oanda.com/)** | Free (demo) | Requires API key, programmatic access |
|
||||
| **[TrueFX](https://truefx.com/)** | Free | Institutional-quality tick data |
|
||||
| **[Kaggle](https://www.kaggle.com/datasets?search=EURUSD+1min)** | Free | Search "OHLCV 1 minute" |
|
||||
| **MetaTrader 5** | Free | Export via `copy_rates_range()` |
|
||||
|
||||
### Step 2: Convert to HDF5
|
||||
|
||||
```python
|
||||
import pandas as pd
|
||||
|
||||
df = pd.read_csv('ohlcv_data.csv', parse_dates=['datetime'])
|
||||
df = df.rename(columns={'open': '$open', 'close': '$close',
|
||||
'high': '$high', 'low': '$low', 'volume': '$volume'})
|
||||
df['instrument'] = 'SYMBOL'
|
||||
df = df.set_index(['datetime', 'instrument'])
|
||||
for col in ['$open', '$close', '$high', '$low', '$volume']:
|
||||
df[col] = df[col].astype('float32')
|
||||
|
||||
import os
|
||||
os.makedirs('git_ignore_folder/factor_implementation_source_data', exist_ok=True)
|
||||
df.to_hdf('git_ignore_folder/factor_implementation_source_data/intraday_pv.h5', key='data', mode='w')
|
||||
```
|
||||
|
||||
### Required HDF5 format
|
||||
|
||||
| Field | Type | Description |
|
||||
|-------|------|-------------|
|
||||
| **Index** | MultiIndex `(datetime, instrument)` | Timestamp + currency pair |
|
||||
| **`$open`** | float32 | Open price |
|
||||
| **`$close`** | float32 | Close price |
|
||||
| **`$high`** | float32 | High price |
|
||||
| **`$low`** | float32 | Low price |
|
||||
| **`$volume`** | float32 | Tick volume |
|
||||
|
||||
**Save location:** `git_ignore_folder/factor_implementation_source_data/intraday_pv.h5`
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment Setup
|
||||
|
||||
Create a `.env` file in the project root:
|
||||
|
||||
```bash
|
||||
# Local LLM (llama.cpp)
|
||||
OPENAI_API_KEY=local
|
||||
OPENAI_API_BASE=http://localhost:8081/v1
|
||||
CHAT_MODEL=qwen3.5-35b
|
||||
|
||||
# Embedding (Ollama)
|
||||
LITELLM_PROXY_API_KEY=local
|
||||
LITELLM_PROXY_API_BASE=http://localhost:11434/v1
|
||||
EMBEDDING_MODEL=nomic-embed-text
|
||||
|
||||
# Paths
|
||||
QLIB_DATA_DIR=~/.qlib/qlib_data/market_data
|
||||
```
|
||||
|
||||
### LLM Server (llama.cpp)
|
||||
|
||||
```bash
|
||||
~/llama.cpp/build/bin/llama-server \
|
||||
--model ~/models/qwen3.6/Qwen3.6-35B-A3B-UD-Q3_K_XL.gguf \
|
||||
--n-gpu-layers 18 \
|
||||
--no-mmap \
|
||||
--port 8081 \
|
||||
--ctx-size 260000 \
|
||||
--parallel 2 \
|
||||
--batch-size 512 --ubatch-size 512 \
|
||||
--host 0.0.0.0 \
|
||||
-ctk q4_0 -ctv q4_0 \
|
||||
--reasoning off
|
||||
```
|
||||
|
||||
> **Important flags:**
|
||||
> - `--ctx-size 260000 --parallel 2` — allocates **2 slots × 130,000 tokens each**.
|
||||
> - `--reasoning off` — **critical**: completely disables Qwen3 chain-of-thought. `--reasoning-budget 0` is not sufficient and produces empty JSON responses.
|
||||
> - `--n-gpu-layers 18` — reduced from max (33) to free ~7 GB VRAM for Kronos-small GPU inference alongside llama-server.
|
||||
> - `-ctk q4_0 -ctv q4_0` — quantises the KV cache to 4-bit, reducing VRAM usage.
|
||||
|
||||
### Data Configuration
|
||||
|
||||
Edit [`data_config.yaml`](data_config.yaml) to customize walk-forward splits:
|
||||
|
||||
```yaml
|
||||
instrument: SYMBOL
|
||||
frequency: 1min
|
||||
data_path: ~/.qlib/qlib_data/market_data
|
||||
|
||||
train_start: "2022-03-14"
|
||||
train_end: "2024-06-30"
|
||||
valid_start: "2024-07-01"
|
||||
valid_end: "2024-12-31"
|
||||
test_start: "2025-01-01"
|
||||
test_end: "2026-03-20"
|
||||
|
||||
market_context:
|
||||
spread_bps: 1.5
|
||||
target_arr: 9.62
|
||||
max_drawdown: 20
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## No GPU? Use OpenRouter
|
||||
|
||||
If you don't have a CUDA-capable GPU, you can run NexQuant using [OpenRouter](https://openrouter.ai) for LLM inference — no local model download required.
|
||||
|
||||
**1. Set up `.env` for OpenRouter:**
|
||||
|
||||
```bash
|
||||
# Chat (OpenRouter)
|
||||
OPENAI_API_KEY=sk-or-v1-<your-openrouter-key>
|
||||
OPENAI_API_BASE=https://openrouter.ai/api/v1
|
||||
CHAT_MODEL=qwen/qwen3-235b-a22b
|
||||
|
||||
# Embedding (Ollama — still required locally)
|
||||
LITELLM_PROXY_API_KEY=local
|
||||
LITELLM_PROXY_API_BASE=http://localhost:11434/v1
|
||||
EMBEDDING_MODEL=nomic-embed-text
|
||||
```
|
||||
|
||||
**2. Skip the llama-server step** — no local LLM server needed.
|
||||
|
||||
**3. Run with the OpenRouter backend:**
|
||||
|
||||
```bash
|
||||
rdagent fin_quant --model openrouter
|
||||
```
|
||||
|
||||
**4. Parallel runs** (uses API concurrency instead of GPU slots):
|
||||
|
||||
```bash
|
||||
python scripts/nexquant_parallel.py --runs 5 --api-keys 1 -m openrouter
|
||||
```
|
||||
|
||||
> Ollama is still required for embeddings even in the OpenRouter path. Install from [ollama.com](https://ollama.com) and run `ollama pull nomic-embed-text` once.
|
||||
> **This repository contains the research framework.** Trading strategies, broker integrations, and live trading infrastructure are available as separate closed-source modules (`git_ignore_folder/`).

## Features
|
||||
|
||||
### 🔄 Iterative Factor Evolution
|
||||
### ⚡ Numba Backtest
|
||||
- 735M bars/second (0.003s for 2.26M bars)
|
||||
- JIT-compiled profit/drawdown/sharpe computation
|
||||
- Signal construction via pandas resample + TA-Lib (~0.4s) is the bottleneck
|
||||
|
||||
NexQuant continuously proposes, implements, and validates new alpha factors:
|
||||
### 🔍 Four Discovery Methods
|
||||
- **Explore**: Random indicator + timeframe + parameters
|
||||
- **Exploit**: Mutation of top-5 SOTA strategies (parameter tweak, indicator swap, timeframe change)
|
||||
- **Optuna**: 20-trial TPE hyperparameter optimization on best strategy
|
||||
- **LightGBM**: ML classifier on SOTA indicator signals (80/20 train/test split)
|
||||
|
||||
- Learns from backtest feedback
|
||||
- Avoids overfitting through walk-forward validation
|
||||
- Discovers non-obvious patterns in order flow, volatility, and session dynamics
|
||||
|
||||
### 🛡️ Trading Protection System
|
||||
|
||||
Automatic risk management to prevent excessive losses:
|
||||
|
||||
- **Max Drawdown Protection** - Pauses trading when drawdown exceeds threshold (default: 15%)
|
||||
- **Cooldown Period** - Enforces mandatory rest period after significant losses (default: 4h after 5% loss)
|
||||
- **Stoploss Guard** - Detects clusters of stoplosses and blocks trading (default: max 5 per day)
|
||||
- **Low Performance Filter** - Filters out consistently underperforming factors (Sharpe < 0.5, Win Rate < 40%)
|
||||
|
||||
### 🧠 Model Architecture Search
|
||||
|
||||
Automatically explores and refines predictive models:
|
||||
|
||||
- Linear baselines (LightGBM, XGBoost)
|
||||
- Deep learning (LSTM, Transformer, Temporal CNN)
|
||||
- Ensemble methods
|
||||
|
||||
### 📚 Knowledge Base
|
||||
|
||||
Built-in knowledge accumulation across loops:
|
||||
|
||||
- Successful factors are archived
|
||||
- Failed attempts inform future proposals
|
||||
- Cross-loop learning improves robustness
|
||||
|
||||
### 🖥️ Interactive UI
|
||||
|
||||
Real-time dashboard for monitoring:
|
||||
|
||||
- Factor performance metrics
|
||||
- Model architecture evolution
|
||||
- Cumulative returns and drawdowns
|
||||
- Code diffs and implementation history
|
||||
|
||||
### 🤖 Kronos Foundation Model Integration
|
||||
|
||||
NexQuant integrates Kronos — an OHLCV foundation model from the NeoQuasar team (AAAI 2026, **MIT License**) — for alpha factor generation:
|
||||
|
||||
| Model | Params | p24 IC | Best For |
|
||||
|-------|--------|--------|----------|
|
||||
| **Kronos-small** (default) | 25M | \|IC\| ≈ 0.09 | OHLCV data |
|
||||
| Kronos-mini | 4.1M | \|IC\| ≈ 0.07 | Low-resource |
|
||||
| Kronos-base | 102M | \|IC\| ≈ 0.002 | Daily/weekly data only |
|
||||
|
||||
Kronos generates 3 prediction-horizon factors automatically on `fin_quant` startup:
|
||||
- `KronosPredReturn_p24` — 24-minute horizon
|
||||
- `KronosPredReturn_p48` — 48-minute horizon
|
||||
- `KronosPredReturn_p96` — 96-minute horizon (best performer)
|
||||
|
||||
The model runs on GPU (CUDA) alongside the llama-server, using CPU as fallback.
|
||||
Factors are persisted in `results/factors/` for use by the strategy orchestrator.
|
||||
|
||||
```bash
|
||||
# Kronos runs automatically with fin_quant (no separate command needed)
|
||||
rdagent fin_quant --loop-n 10 --model local
|
||||
|
||||
# Model size is auto-detected and configurable via env
|
||||
# Set KRONOS_MODEL_SIZE=base to use the 102M-param model
|
||||
```
|
||||
### 📊 TA-Lib Integration
|
||||
- 17 indicators with full parameter ranges
|
||||
- Auto-guard against bad parameters (negative/zero values that crash TA-Lib)
|
||||
- Multi-timeframe voting with configurable threshold
|
||||
|
||||
### 🔒 Security & Quality
|
||||
|
||||
Automated quality assurance:
|
||||
|
||||
- **1,125+ collected tests** — deep property-based, fuzzing, and hypothesis tests on every commit
|
||||
- **Bandit Security Scanner** — pre-commit security checks
|
||||
- **Weekly Dependency Audit** — automated vulnerability scan via GitHub Actions
|
||||
- **Closed-source detection** — CI verifies no local/ files are accidentally committed
|
||||
- 0 Dependabot alerts, 0 CodeScan alerts
|
||||
- No proprietary terms in git history
|
||||
- Closed-source detection CI

> **Note on `rdagent/`**: The LLM-based R&D framework (`rdagent fin_quant`) is part of the codebase but the Qlib/CoSTEER pipeline currently produces zero factors. The primary strategy discovery path is the Numba-based loop in `scripts/`.

## Backtest Integrity
|
||||
|
||||
Every backtest result is automatically verified at runtime against 10 mathematical invariants.
|
||||
The verifier runs in **<1ms** and catches corrupted/missing/flipped metrics before they enter the factor database.
|
||||
|
||||
### Runtime checks (every backtest)
|
||||
| Check | Constraint |
|
||||
|-------|-----------|
|
||||
| Max Drawdown | `-1.0 ≤ mdd ≤ 0.0` |
|
||||
| Win Rate | `0.0 ≤ wr ≤ 1.0` |
|
||||
| Sharpe Ratio | `sharpe` must be finite |
|
||||
| Total Return | `total_return` must be finite |
|
||||
| Trade Count | `n_trades ≥ 0` |
|
||||
| Sign consistency | `sign(sharpe) == sign(annual_return)` |
|
||||
| Status | Must be `success` or `failed` |
|
||||
|
||||
### Test suite (CI + pre-commit)
|
||||
```bash
|
||||
pytest test/ -q # 1,125+ collected, property-based + fuzzing
|
||||
pytest test/backtesting/ -q # backtest engine deep tests
|
||||
```
|
||||
|
||||
**Coverage**: IC linear invariance, forward-return alignment, cross-implementation validation, ground-truth hand-computed scenarios, look-ahead bias detection, edge cases (all-NaN, constant, zero-variance, 1-bar, empty series), Monte Carlo p-value, walk-forward rolling, buy-and-hold equality, property-based testing (hypothesis: cost monotonicity, signal inversion, max-DD invariants), fuzzing (1,000 random backtest results), autopilot failure recovery, threshold rescaling, API key distribution, ML model acceptance criteria.
