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 positions
• has_positions: Binary flag

Market Features (per asset)

• price: Current normalized price (price / 100)
• return: Daily log return
• volatility: 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_efficiency

Components

1. Return Component (60%)

   • Daily return scaled by 100
   • R_return = (V_t - V_{t-1}) / V_{t-1} * 100
   • Range: [-10, +10]

2. Risk Penalty (20%)

   • Drawdown penalty: -5 * (max_value - current_value) / max_value
   • Encourages capital preservation
   • Range: [-5, 0]

3. Trade Efficiency (20%)

   • Reward from closing profitable trades
   • Last 5 closed trade PnLs averaged
   • Trade_efficiency = mean(pnl_5trades) * 0.01
   • Range: [-0.5, +0.5]

Total Reward Range

R(t) ∈ [-10, +10]  (clipped)

Example Reward Scenarios

Scenario	Return	Drawdown	Trades	Total
Profitable + no drawdown + winning trades	+0.6	0	+0.1	+0.7
Flat day with drawdown	0	-0.5	0	-0.5
Loss with winning trade	-0.6	-1	+0.2	-1.4

from agents import TechnicalAgent

agent = TechnicalAgent(
    symbols=['ASSET1'],
    rsi_threshold=(30, 70),  # oversold, overbought
)

from agents import RandomAgent
from tasks import TaskFactory

task = TaskFactory.create_easy_task()
loader = MarketDataLoader()
env = TradingEnvironment(task.config, loader)
agent = RandomAgent(symbols=task.config.symbols)

state, info = env.reset(seed=42)
done = False
episode_reward = 0

while not done:
    action = agent.act(state, info)
    state, reward, done, info = env.step(action)
    episode_reward += reward

print(f"Episode reward: {episode_reward:.4f}")
print(f"Final portfolio: ${info['portfolio_value']:.2f}")

Example 2: Running Evaluation

from tasks import TaskFactory, Evaluator

def run_agent_on_task(agent, task, num_episodes=5):
    """Run agent on task and evaluate."""
    
    from env import TradingEnvironment, MarketDataLoader
    
    results = []
    
    for episode in range(num_episodes):
        loader = MarketDataLoader()
        env = TradingEnvironment(task.config, loader)
        
        state, info = env.reset(seed=42 + episode)
        
        portfolio_values = [env.get_portfolio_value()]
        returns = []
        
        done = False
        while not done:
            action = agent.act(state, info)
            state, reward, done, info = env.step(action)
            
            portfolio_values.append(env.get_portfolio_value())
            returns.append(info['metrics']['step_return'])
        
        metrics = Evaluator.evaluate_episode(
            portfolio_values, returns, []
        )
        results.append(metrics)
    
    return results

# Usage
task = TaskFactory.create_medium_task()
metrics_list = run_agent_on_task(random_agent, task, num_episodes=5)

avg_score = sum(m.score() for m in metrics_list) / len(metrics_list)
print(f"Average score: {avg_score:.1f}/100")

---

Evaluation and Metrics

EvaluationMetrics

from tasks import EvaluationMetrics

metrics = EvaluationMetrics(
    total_return: float,         # Total return (0.05 = 5%)
    annualized_return: float,    # Annualized return
    max_drawdown: float,         # Worst peak-to-trough loss
    sharpe_ratio: float,         # Risk-adjusted return
    sortino_ratio: float,        # Downside risk-adjusted return
    win_rate: float,             # % of profitable steps
    profit_factor: float,        # Gross profit / gross loss
    num_trades: int,             # Total number of trades
    avg_trade_duration: float,   # Average bars per trade
    avg_win: float,              # Average winning trade
    avg_loss: float,             # Average losing trade
    consecutive_wins: int,       # Max consecutive wins
    consecutive_losses: int,     # Max consecutive losses
)

score = metrics.score()  # Returns 0-100 composite score

Composite Score

The score combines multiple objectives:

score = (
    40% * min(return, 1.0) +
    30% * min(sharpe / 2, 1.0) +
    20% * win_rate +
    10% * (1.0 - max(drawdown / 0.5, 1.0))
) * 100

Multi-Agent Comparison

from tasks import Evaluator

results = {
    'RandomAgent': metrics1,
    'MomentumAgent': metrics2,
    'TechnicalAgent': metrics3,
}

report = Evaluator.compare_agents(results)
print(report)

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_reward

Q: 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")
