🚀 Stock Trading RL Agent - Advanced PPO Implementation

A state-of-the-art reinforcement learning agent for algorithmic stock trading using Proximal Policy Optimization (PPO)

🔥 Quick Start • 📊 Performance • 💡 Usage • 🛠️ Technical Details

📈 Model Overview

This model represents a sophisticated reinforcement learning trading agent trained using the Proximal Policy Optimization (PPO) algorithm. The agent learns to make optimal trading decisions across multiple stocks by analyzing technical indicators, market patterns, and portfolio states.

🎯 Key Highlights

• 🧠 Algorithm: PPO with Multi-Layer Perceptron policy
• 💰 Action Space: Hybrid continuous/discrete (Action Type + Position Sizing)
• 📊 Observation Space: 60-day lookback window with technical indicators
• 🏆 Training: 500,000 timesteps across 5 major stocks
• ⚡ Performance: Up to 7,243% returns with risk management

🚀 Quick Start

Installation

pip install stable-baselines3 yfinance pandas numpy scikit-learn

For data preparation, you can use Enhanced Enviroment and Stock data processor automated classes for data and enviroment preparation in python files provided in directory

Load and Use the Model

from stable_baselines3 import PPO
import pickle
import numpy as np

# Load the trained model
model = PPO.load("best_model.zip")

# Load the data scaler
with open("scaler.pkl", "rb") as f:
    scaler = pickle.load(f)

# Example prediction
obs = your_observation_data  # Shape: (n_features,)
action, _states = model.predict(obs, deterministic=True)

# Interpret action
action_type = int(action[0])  # 0: Hold, 1: Buy, 2: Sell
position_size = action[1]     # 0-1: Fraction of available capital

📋 State Space & Features

📊 Technical Indicators

The agent observes the following features for each stock:

• 📈 Trend Indicators: SMA (20, 50), EMA (12, 26)
• 📊 Momentum: RSI, MACD, MACD Signal, MACD Histogram
• 🎯 Volatility: Bollinger Bands (Upper, Lower, %B)
• 💹 Price/Volume: Open, High, Low, Close, Volume
• 💰 Portfolio State: Balance, Position, Net Worth, Returns

🔄 Action Space

The agent outputs a 2-dimensional action:

1. Action Type (Discrete):

   • 0: Hold position
   • 1: Buy signal
   • 2: Sell signal

2. Position Size (Continuous):

   • Range: [0, 1]
   • Represents fraction of available capital to use

🎯 Usage Examples

📈 Basic Trading Loop

import yfinance as yf
import pandas as pd
from stable_baselines3 import PPO

# Load model and scaler
model = PPO.load("best_model.zip")
with open("scaler.pkl", "rb") as f:
    scaler = pickle.load(f)

# Get live data
ticker = "AAPL"
data = yf.download(ticker, period="3mo", interval="1d")

# Prepare observation (implement your feature engineering)
obs = prepare_observation(data, scaler)  # Your preprocessing function

# Get trading decision
action, _states = model.predict(obs, deterministic=True)
action_type = ["HOLD", "BUY", "SELL"][int(action[0])]
position_size = action[1]

print(f"Action: {action_type}, Size: {position_size:.2%}")

🔄 Backtesting Framework

def backtest_strategy(model, data, initial_balance=10000):
    """
    Backtest the trained model on historical data
    """
    balance = initial_balance
    position = 0
    
    for i in range(len(data)):
        obs = prepare_observation(data[:i+1])
        action, _ = model.predict(obs, deterministic=True)
        
        # Execute trading logic
        action_type = int(action[0])
        position_size = action[1]
        
        if action_type == 1:  # Buy
            shares_to_buy = (balance * position_size) // data.iloc[i]['Close']
            position += shares_to_buy
            balance -= shares_to_buy * data.iloc[i]['Close']
        elif action_type == 2:  # Sell
            shares_to_sell = position * position_size
            position -= shares_to_sell

from stable_baselines3.common.env_checker import check_env
from your_trading_env import StockTradingEnv

env = StockTradingEnv(
    tickers=["AAPL", "MSFT", "GOOGL"],
    initial_balance=10000,
    transaction_cost=0.001
)

# Verify environment
check_env(env)

# Load and test model
model = PPO.load("best_model.zip")
obs = env.reset()
action, _states = model.predict(obs)

📊 Real-time Trading Integration

import asyncio
import websocket

async def live_trading_loop():
    """
    Example live trading implementation
    """
    while True:
        # Get real-time market data
        market_data = await get_market_data()
        
        # Prepare observation
        obs = prepare_observation(market_data)
        
        # Get model prediction
        action, _ = model.predict(obs)
        
        # Execute trade (implement your broker API)
        if int(action[0]) != 0:  # Not hold
            await execute_trade(action)
        
        await asyncio.sleep(60)  # Wait 1 minute
