State Space
State Vector (Normalized)
The environment returns a normalized 64-dimensional state vector:
state = np.concatenate([
portfolio_features, # [4] cash_ratio, leverage, num_positions, has_positions
market_features, # [12] prices, returns, volatilities for 4 assets
technical_features, # [16] RSI, MACD, ATR, Bollinger Bands for 4 assets
position_features, # [12] quantities, entry_prices, PnLs for 4 positions
], dtype=np.float32) # Total: 44 dimensions (varies by num_assets)Feature Details
Portfolio Features
cash_ratio: Cash / Initial Capital (0-1)leverage: Total Position Value / Portfolio Value (0-5)num_positions: Count of open positionshas_positions: Binary flag
Market Features (per asset)
price: Current normalized price (price / 100)return: Daily log returnvolatility: Rolling annualized volatility
Technical Features (per asset)
rsi: Relative Strength Index (0-100, normalized to 0-1)macd: MACD value (normalized)atr: Average True Range (normalized)bb_upper: Bollinger Band upper band (normalized)
Position Features (per position)
quantity: Position size (normalized)entry_price: Entry price (normalized)pnl_pct: Unrealized P&L percentage
Normalization
States are normalized using robust scaling:
z = (x - median) / (MAD + 1e-8)
z = clip(z, -10, 10)This approach is robust to outliers and preserves information.
Action Space
Discrete Actions
Each action specifies:
- Symbol: Which asset to trade
- OrderType: BUY (1), SELL (-1), or HOLD (0)
- Quantity: Number of shares (0-100)
Action Class
from env import Action, OrderType
action = Action(
symbol='ASSET1',
order_type=OrderType.BUY,
quantity=25.0,
price=None, # None = market order
)
state, reward, done, info = env.step(action)Action Constraints
- Minimum Order Size: 1 share (configurable)
- Maximum Position Size: 25-50% of portfolio
- Max Leverage: 2-5x (configurable)
- Quantity Validation: Non-negative quantities only
Reward Function
Composite Reward (Multi-objective Optimization)
R(t) = 0.6 * return_component + 0.2 * risk_penalty + 0.2 * trade_efficiencyComponents
- Return Component (60%)
- Daily return scaled by 100
- Rreturn = (Vt - V{t-1}) / V{t-1} * 100
- Range: [-10, +10]
- Risk Penalty (20%)
- Drawdown penalty: -5 * (maxvalue - currentvalue) / max_value
- Encourages capital preservation
- Range: [-5, 0]
- Trade Efficiency (20%)
- Reward from closing profitable trades
- Last 5 closed trade PnLs averaged
- Tradeefficiency = mean(pnl5trades) * 0.01
- Range: [-0.5, +0.5]
Total Reward Range
R(t) ∈ [-10, +10] (clipped)Example Reward Scenarios

FAQ
Q: How do I use this with my RL algorithm?
A: The environment follows standard OpenAI Gym API:
state, info = env.reset()
state, reward, done, info = env.step(action)Any RL library (Stable-Baselines3, RLlib, etc.) can use this.
Q: Can I use real market data?
A: Yes! Load from CSV:
loader = MarketDataLoader()
loader.load_from_csv('data/ASSET1.csv')
env = TradingEnvironment(config, loader)Q: How do I modify the reward function?
A: Edit the _calculate_reward() method in environment.py:
def _calculate_reward(self, prev_value, current_value):
# Your custom reward logic here
return custom_rewardQ: Can I add more indicators?
A: Yes! Add to TechnicalIndicators.compute_all():
indicators['my_indicator'] = TechnicalIndicators.my_indicator(prices)Q: How do I evaluate on a specific task?
A: Use TaskFactory:
task = TaskFactory.get_task_by_name("HardTrade")
# or
task = TaskFactory.get_task_by_difficulty("hard")Contributing
