The OpenAI Gym – MetaTrader 5 Simulator, also known as gym-mtsim, is a powerful tool designed for trading enthusiasts and developers looking to explore reinforcement learning (RL) in the financial market. With this simulator, users can delve into trading strategies involving Forex, Stocks, Crypto, and Futures on the popular MetaTrader 5 platform. This article will guide you through the process of installing and utilizing this simulator.

Prerequisites

Before diving into the usage of gym-mtsim, ensure you have the following prerequisites prepared:

• MetaTrader 5: Download and install the software from MetaTrader 5. After installation, open a demo account on any broker, which is automatically set up by default.

Installation Steps for gym-mtsim

With MetaTrader 5 installed, follow these steps to set up the gym-mtsim library:

• Via PIP:

  bash
  pip install gym-mtsim
  

• From Repository:

  bash
  git clone https://github.com/AminHP/gym-mtsim
  cd gym-mtsim
  pip install -e .
  

• Upgrade Option:

  bash
  pip install --upgrade --no-deps --force-reinstall https://github.com/AminHP/gym-mtsim/archive/main.zip
  

Install Required Packages

You will need the stable-baselines3 package to run certain examples. Install it from here.

Understanding the Components

At the heart of gym-mtsim, you have several essential components:

• SymbolInfo: Contains vital properties of trading symbols.
• Order: Holds information about specific orders placed during trading.
• MtSimulator: Simulates the main functions of MetaTrader, allowing for replication of trading behaviors.
• MtEnv: Integrates with Gym, acting as the environment for reinforcement learning applications.

An Analogy for Explanation

Think of gym-mtsim as a sophisticated video game designed for trading. Just like a game simulates a virtual world where players go on quests and make decisions based on their strategies, gym-mtsim creates a virtual trading environment where you can “play” with your trading algorithms. Each component of the simulator, from SymbolInfo to MtSimulator, acts like different characters or tools you can use within this trading game. You need to gear up (load data and run simulations) before heading out into the market to test your strategies!

Writing Code to Use gym-mtsim

Here’s how you can create a simulator with custom parameters:

python
import pytz
from datetime import datetime, timedelta
from gym_mtsim import MtSimulator, OrderType, Timeframe, FOREX_DATA_PATH

sim = MtSimulator(
    unit='USD',
    balance=10000.,
    leverage=100.,
    stop_out_level=0.2,
    hedge=False,
)

if not sim.load_symbols(FOREX_DATA_PATH):
    sim.download_data(
        symbols=['EURUSD', 'GBPCAD', 'GBPUSD', 'USDCAD', 'USDCHF', 'GBPJPY', 'USDJPY'],
        time_range=(
            datetime(2021, 5, 5, tzinfo=pytz.UTC),
            datetime(2021, 9, 5, tzinfo=pytz.UTC)
        ),
        timeframe=Timeframe.D1
    )
    sim.save_symbols(FOREX_DATA_PATH)

Placing and Managing Orders

Now, let’s place some orders:

python
sim.current_time = datetime(2021, 8, 30, 0, 17, 52, tzinfo=pytz.UTC)
order1 = sim.create_order(
    order_type=OrderType.Buy,
    symbol='GBPCAD',
    volume=1.,
    fee=0.0003,
)
sim.tick(timedelta(days=2))
order2 = sim.create_order(
    order_type=OrderType.Sell,
    symbol='USDJPY',
    volume=2.,
    fee=0.01,
)
sim.tick(timedelta(days=5))
state = sim.get_state()
print(f'Balance: {state["balance"]}, Equity: {state["equity"]}, Margin: {state["margin"]}, Free Margin: {state["free_margin"]}, Margin Level: {state["margin_level"]}')

Troubleshooting and Tips

If you encounter any issues during installation or usage, consider the following troubleshooting tips:

• Ensure MetaTrader 5 is running with a demo account correctly set up.
• Check for missing libraries or dependencies; you might need to reinstall the gym-mtsim package.
• Refer to the documentation on GitHub if you have specific questions regarding the API.
