What is Algo Trading?           

Algo Trading, or Algorithmic Trading, refers to the use of computer algorithms/program to execute trades based on predefined criteria. Python is one of the widely used languages for making Algorithms for Automated Trading. Traders make Algorithmic based on their predetermined strategies with properly defined parameters such as buying price, stop loss, trailing points, etc. This method allows for high-speed transactions and can significantly reduce human error. In India, the percentage of traders using Algo Trading and deploying Algo Trading strategies varies, but the range is generally 50% to 60%.

Here's a categorised breakdown based on the latest data

Percentage of Algo Trading in India

·  Overall Usage:

o Reports indicate that approximately 50% to 55% of traders in India utilise Algorithmic Trading methods.

o  A more recent update suggests that this figure has increased to around 60%, particularly in high-frequency trading (HFT) contexts.

·  Institutional vs Retail Traders:

o  Among institutional traders, a significant majority (about 97% of Foreign Portfolio Investors (FPIs) and 96% of proprietary traders) uses Algorithmic Trading for executing trades, which shows its dominance in professional trading environments.

o  Only about 13% of individual retail traders engage in Algo Trading, indicating a big difference in adoption rates between retail and institutional market participants.

Global Comparison

In comparison to India, Algorithmic trading has a much larger share of total trading volume in developed markets:

o  Approximately 80% of equity transactions globally are executed via Algorithms.

o  In the US and Europe, this figure ranges from 60% to 85%, shows how Algo Trading is more uses in these markets compared to India.

Why Use Python for Algorithmic Trading?

Python is one of the leading and widely used programming languages for Algo Trading in 2025 due to its simplicity, available powerful libraries and large community. Here are some reasons why Python would be the best choice to make Algo Trading strategies:

  • Ease of Learning: Python's syntax is very easy to use, making it easy to deploy and create algorithms for Automated Trading.
  • Libraries: Python offers Libraries such as Pandas for data manipulation, NumPy for numerical calculations, and Matplotlib for data visualisation which is important to create any Algo Trading strategy.
  • Community Support: Python has a vast community provides resources, tutorials, and forums that help traders troubleshoot issues and learn new techniques.

Getting Started with Algorithmic Trading in Python

Step 1: Setting Up Your Coding Environment

Let’s setup your environment:

  • Install Python: To Download the latest version of Python visit the Python official website by clicking here.
  • Choose an IDE: Integrated Development Environments (IDEs) like Jupyter Notebook, Visual Studio or PyCharm provide you an editor where you can code your Algo Trading strategy fast.
  • Create a Virtual Environment (Optional): Create a separate Python environment for your automated trading project, this is an optional step. You can use local or global environments as well. Use the following commands in your command prompt or terminal:
python -m venv myenv
source myenv/bin/activate        # For Mac/Linux
myenv\Scripts\activate              # For Windows

Step 2: Understand Basic Trading Concepts

Make yourself familiar with basic trading concepts such as:

  • Market Orders vs Limit Orders: Know when to use each type based on your Algo Trading Strategy.
  • Technical Indicators: Learn about indicators like Moving Averages, RSI (Relative Strength Index), and MACD (Moving Average Convergence Divergence) that help in decision-making.

Step 3: Start Coding Your First Strategy

Let's create a simple moving average crossover strategy using Python. This strategy generates buy signals when a short-term moving average crosses above a long-term moving average.
import yfinance as yf
import numpy as np
import matplotlib.pyplot as plt
 
# Fetch stock data
def fetch_stock_data(ticker, start_date, end_date):
    data = yf.download(ticker, start=start_date, end=end_date)
    return data
 
# Calculate Moving Averages
def calculate_moving_averages(data, short_window, long_window):
    data['SMA_Short'] = data['Close'].rolling(window=short_window).mean()
    data['SMA_Long'] = data['Close'].rolling(window=long_window).mean()
    return data
 
# Generate Buy/Sell Signals
def generate_signals(data):
    data['Signal'] = 0
    data['Signal'] = np.where(data['SMA_Short'] > data['SMA_Long'], 1, 0)
    data['Position'] = data['Signal'].diff()
    return data
 
# Plot Stock Data with Signals
def plot_signals(data, ticker):
    plt.figure(figsize=(12, 6))
    plt.plot(data['Close'], label='Stock Price', alpha=0.5)
    plt.plot(data['SMA_Short'], label='Short(20) SMA', alpha=0.75)
    plt.plot(data['SMA_Long'], label='Long(50) SMA', alpha=0.75)
    plt.scatter(data.index[data['Position'] == 1], data['Close'][data['Position'] == 1],
                label='Buy Signal', marker='^', color='green', alpha=1)
    plt.scatter(data.index[data['Position'] == -1], data['Close'][data['Position'] == -1],
                label='Sell Signal', marker='v', color='red', alpha=1)
    plt.title(f'{ticker} Trading Signals')
    plt.xlabel('Date')
    plt.ylabel('Close Price')
    plt.legend()
    plt.show()
 
# Main Function
if __name__ == "__main__":
    # Inputs
    ticker = "Reliance.NS"  # Example: RELIANCE INDUSTRIES (NSE)
    start_date = "2023-01-01"
    end_date = "2024-12-31"
    short_window = 20  # Short-term SMA
    long_window = 50  # Long-term SMA
 
    # Fetch data
    data = fetch_stock_data(ticker, start_date, end_date)
 
    # Calculate Moving Averages
    data = calculate_moving_averages(data, short_window, long_window)
 
    # Generate Trading Signals
    data = generate_signals(data)
 
    # Display Buy/Sell Signals
    print(data[data['Position'] == 1][['Close', 'SMA_Short', 'SMA_Long']].head())  # Buy Signals
    print(data[data['Position'] == -1][['Close', 'SMA_Short', 'SMA_Long']].head())  # Sell Signals
 
    # Plot Signals
    plot_signals(data, ticker)

This is a simple Algorithm created to generate the buy and sell signal of 'RELIANCE INDUSTRIES' using Simple Moving Average crossovers. Use your own understanding, research and backtest to create and deploy any Algo Trading strategy.

Step 4: Backtest Your Strategy 

Backtesting your trading strategy using historical/past data is crucial to evaluate the effectiveness and accuracy of your Algo Trading strategy. You can utilize Python libraries like backtrader or zipline for this purpose, or you can use online platforms to backtest your Algo Trading strategy.

Step 5: Implementing the Strategy with APIs

This is one of the most important steps to make your Algo Trading strategy fully functional and execute trades automatically; you'll need to integrate the broker's API with your Python program. Popular APIs include:

  • Bigul Bonanza API: One of the easiest to use and implement in your Algo Trading Strategy, to completely manage from order punching to risk management is easy, all with low latency.
  • Interactive Brokers API: Suitable for international trading.

Make sure to read the API documentation of respective API providers thoroughly to understand how to place orders programmatically in your Python or any language programs.

Step 6: Risk Management

Risk management is very important approach in trading and so is in when you deploy you strategy on Algorithm. Effective risk management strategies are vital in Algorithmic Trading. Implementing stop-loss orders and keeping managed position size is effective step to protect your capital.

Advanced Topics in Algorithmic Trading

Once you're comfortable with basic strategies, you can explore more advanced Algo Trading concepts:

  • Machine Learning: Integrate machine learning models using libraries like Scikit-Learn to predict market movements based on historical data, Python language would come beneficial here as well to implement.
  • High-Frequency Trading (HFT): Learn about strategies that involve executing a large number of orders at extremely high speeds.
  • Sentiment Analysis: Implement sentiment analyse techniques in you Algo Trading strategy using news articles or social media sentiment to gauge market trends.
