What is Portfolio Rebalancing?
Portfolio rebalancing is the process of realigning asset weights in an investment portfolio. In crypto, rebalancing helps manage risk and maintain a desired allocation despite price fluctuations. For instance, if your portfolio is split 60% Bitcoin (BTC) and 40% Ethereum (ETH), a sudden rise in BTC’s price could skew your allocation. Rebalancing restores the portfolio to its target allocation.
How AI & Machine Learning Enhance Rebalancing
With machine learning, you can predict price trends and make smarter decisions about when and how to rebalance your portfolio. Using TensorFlow, we’ll train an LSTM (Long Short-Term Memory) model to forecast price movements based on historical data.
Prerequisites
Before getting started, ensure you have a basic working knowledge of the following:
Python
This project heavily relies on Python programming, and hence, it is essential to understand Python syntax, libraries, and how to manipulate data. Ensure Python (version 3.8 or higher) is installed on your system. Python’s package manager, pip, is required for installing the dependencies used in this project – we’ll outline the installation steps below.
CoinGecko API
We will use the CoinGecko API’s free Demo plan to fetch market chart data for cryptocurrencies—specifically, the endpoint /coins/{id}/market_chart.
The Demo API plan is freely accessible to anyone with a CoinGecko account, capped at 10,000 calls monthly and a 30 calls/min rate limit. Explore 60+ endpoints on our API documentation, or create a Demo account to try it out!
Machine Learning Basics & Familiarity with TensorFlow
Familiarity with machine learning’s core concepts, such as datasets, models, training, testing, and evaluation, will help you understand the workflow.
Specifically, we’ll be leveraging the TensorFlow machine learning framework, used for creating and training models. Familiarity with TensorFlow or a similar library (like PyTorch) is crucial to implementing the LSTM model used in this project.
Data Visualization Basics
We’ll use Matplotlib for visualizing data and predictions – understanding how to create line plots and customize visualizations will be helpful.
Familiarity with NumPy (for numerical operations) and Pandas (for handling tabular data) is essential, as these libraries form the backbone of data manipulation in Python.
Text Editor or IDE
A robust text editor or IDE like Visual Studio Code (VSCode) or PyCharm is recommended for coding. These tools provide features such as syntax highlighting, debugging, and extensions to improve the development experience.
Python & Pip Package Installation using Visual Studio Code
To install Python and pip using VSCode, first download and install Python from the official Python website, ensuring to check the box that says “Add Python to PATH” during installation. Once installed, verify Python and pip are working by opening a terminal and running python –version and pip –version. If you’re using macOS or Linux, follow the platform-specific instructions on the Python website.
Next, download and install Visual Studio Code from the VSCode website, and then open VSCode. Install the Python extension by navigating to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on macOS), searching for “Python” by Microsoft, and clicking “Install.” After that, you can verify pip is installed by running pip –version in the terminal. If it’s not installed, you can run python -m ensurepip –upgrade to install it. You can now install any required Python packages using pip, for example, pip install requests.
For project isolation, it’s recommended to use a virtual environment. To create one, run python -m venv venv in the terminal, then activate it with .\venv\Scripts\activate on Windows or source venv/bin/activate on macOS/Linux. With the virtual environment active, install any dependencies needed for your project using pip. To deactivate, simply type deactivate. You can run your Python code by creating a .py file in VSCode and running it via the terminal or by right-clicking it and selecting “Run Python File in Terminal.” This setup ensures you have everything to start coding with Python in VSCode.
Note: To install TensorFlow on Windows, use Python 3.11. Create a virtual environment and install TensorFlow with pip install tensorflow pandas numpy requests sci-kit-learn flask. Switching to Python 3.11 solved the compatibility issue.
With these prerequisites in place, you’ll be well-equipped to start building your AI-powered crypto portfolio rebalancing tool. Let’s dive in!
File Structure of the Crypto Portfolio Rebalancer
Here is the file structure for the Crypto Portfolio Rebalancer project:
/project-directory
/templates
index.html
/static
script.js
app.py
rebalance.py
Step 1. Crypto Portfolio Rebalancing Code Script
In this section, we’ll delve into rebalance.py, the key script that powers our AI-powered crypto portfolio rebalancing tool. We’ll explore the essential imports, functions, and logic that make this program work.
import requests
import numpy as np
import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense
from sklearn.preprocessing import MinMaxScaler
# Step 1: Fetch Historical Data Using CoinGecko API
def fetch_historical_data(crypto_id, currency='usd', days="90", api_key=None):
url = f"
params = {'vs_currency': currency, 'days': days}
headers = {'Authorization': f'Bearer {api_key}'} if api_key else {}
response = requests.get(url, params=params, headers=headers)
data = response.json()
prices = [price[1] for price in data['prices']]
return prices
# Step 2: Preprocess the Data
def preprocess_data(prices, sequence_length=30):
scaler = MinMaxScaler()
prices = np.array(prices).reshape(-1, 1)
scaled_prices = scaler.fit_transform(prices)
sequences = []
targets = []
for i in range(len(scaled_prices) - sequence_length):
sequences.append(scaled_prices[i:i + sequence_length])
targets.append(scaled_prices[i + sequence_length])
return np.array(sequences), np.array(targets), scaler
# Step 3: Build and Train the LSTM Model
def build_lstm_model(input_shape):
model = Sequential([
LSTM(50, return_sequences=True, input_shape=input_shape),
LSTM(50),
Dense(1)
])
model.compile(optimizer="adam", loss="mse")
return model
# Step 4: Predict Future Prices Using LSTM Model
def predict_price(model, sequences, scaler):
# Predict the next price
last_sequence = sequences[-1].reshape(1, -1, 1)
predicted_price_scaled = model.predict(last_sequence)
# Inverse transform to get the actual price
predicted_price = scaler.inverse_transform(predicted_price_scaled)
return float(predicted_price[0][0]) # Convert to standard float
# Step 5: Rebalance the Portfolio
def rebalance_portfolio(current_allocation, predicted_prices, target_allocation):
# Calculate the current total value of the portfolio
current_value = sum(current_allocation)
# Calculate target values based on current total value and target allocation percentages
target_values = [current_value * ta for ta in target_allocation]
# Calculate adjustments required to reach target values
adjustments = []
for current, target, predicted in zip(current_allocation, target_values, predicted_prices):
# Adjust the current allocation based on predicted prices to meet the target allocation
adjusted_value = target / predicted
adjustments.append(adjusted_value - current)
# Round adjustments and predicted prices to 3 decimal places for consistency
adjustments = [round(adj, 3) for adj in adjustments]
predicted_prices = [round(price, 3) for price in predicted_prices]
return adjustments, predicted_prices
In summary, rebalance.py is designed to fetch historical price data, preprocess it for model training, build and train an LSTM model to predict future prices, and then use these predictions to rebalance a cryptocurrency portfolio according to target allocations. Each step is critical for the overall functionality of the rebalancing tool, ensuring that the portfolio is aligned with future market predictions. This results in a dynamic and effective portfolio management strategy powered by AI.
Step 2. Build the Frontend User Interface
Here, we’ll create the HTML and CSS for the user interface (UI) that allows users to input their portfolio and target allocation.

Step 3. Add Interactivity with JavaScript
To make the UI functional, we’ll connect it to the Python backend for predictions and portfolio rebalancing using JavaScript.
JavaScript File (script.js)
document.addEventListener("DOMContentLoaded", async function() {
const response = await fetch("/current_prices");
const data = await response.json();
document.getElementById("current-btc-price").innerText = `Current BTC Price: $${data.btc_price.toFixed(3)}`;
document.getElementById("current-eth-price").innerText = `Current ETH Price: $${data.eth_price.toFixed(3)}`;
});
document.getElementById("rebalance-form").addEventListener("submit", async function (event) {
event.preventDefault();
// Show the loading message
document.getElementById("loading").style.display = "block";
document.getElementById("results").innerHTML = "";
// Reset the progress bar
const progressBar = document.getElementById("progress-bar");
progressBar.style.width = "0%";
const btcAllocation = parseFloat(document.getElementById("btc-allocation").value);
const ethAllocation = parseFloat(document.getElementById("eth-allocation").value);
const targetBTC = parseFloat(document.getElementById("target-btc").value) / 100;
const targetETH = parseFloat(document.getElementById("target-eth").value) / 100;
const response = await fetch("/rebalance", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
current_allocation: [btcAllocation, ethAllocation],
target_allocation: [targetBTC, targetETH],
}),
});
const result = await response.json();

console.log(result); // Log the result to see if data is returned
displayResults(result.adjustments, result.predicted_prices);
// Hide the loading message
document.getElementById("loading").style.display = "none";
});
function updateProgressBar(progress) {
const progressBar = document.getElementById("progress-bar");
progressBar.style.width = `${progress}%`;
}
function displayResults(adjustments, predicted_prices) {
const resultsDiv = document.getElementById("results");
resultsDiv.innerHTML = `
Rebalancing Suggestions
Adjust BTC by: $${adjustments[0].toFixed(3)}
Adjust ETH by: $${adjustments[1].toFixed(3)}
Predicted Prices
Predicted BTC Price: $${predicted_prices[0].toFixed(3)}
Predicted ETH Price: $${predicted_prices[1].toFixed(3)}
`;
}
// Example of updating the progress bar incrementally
async function simulateProgress() {
for (let i = 0; i
updateProgressBar(i);
await new Promise(resolve => setTimeout(resolve, 100)); // Simulate training time
}
}
// Call simulateProgress when the form is submitted
document.getElementById("rebalance-form").addEventListener("submit", async function (event) {
event.preventDefault();
// Show the loading message
document.getElementById("loading").style.display = "block";
document.getElementById("results").innerHTML = "";
// Reset the progress bar
const progressBar = document.getElementById("progress-bar");
progressBar.style.width = "0%";
const btcAllocation = parseFloat(document.getElementById("btc-allocation").value);
const ethAllocation = parseFloat(document.getElementById("eth-allocation").value);
const targetBTC = parseFloat(document.getElementById("target-btc").value) / 100;
const targetETH = parseFloat(document.getElementById("target-eth").value) / 100;
// Start simulating progress
simulateProgress();
const response = await fetch("/rebalance", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
current_allocation: [btcAllocation, ethAllocation],
target_allocation: [targetBTC, targetETH],
}),
});
const result = await response.json();

console.log(result); // Log the result to see if data is returned
displayResults(result.adjustments, result.predicted_prices);
// Hide the loading message
document.getElementById("loading").style.display = "none";
});
Step 4. Create the Python Backend
The backend will handle the prediction and rebalancing logic. Use Flask to create an API that connects the JavaScript frontend to the Python logic.
Flask Server (app.py)
from flask import Flask, request, jsonify, render_template
from rebalance import fetch_historical_data, preprocess_data, build_lstm_model, predict_price, rebalance_portfolio
from tqdm import tqdm
app = Flask(__name__)
# Serve the index.html file
@app.route("
def home():
return render_template('index.html')
@app.route('/current_prices', methods=['GET'])
def current_prices():
api_key = 'CG-api_key '
btc_prices = fetch_historical_data('bitcoin', api_key=api_key)
eth_prices = fetch_historical_data('ethereum', api_key=api_key)
current_btc_price = round(btc_prices[-1], 3) # Latest BTC price
current_eth_price = round(eth_prices[-1], 3) # Latest ETH price
return jsonify({"btc_price": current_btc_price, "eth_price": current_eth_price})
@app.route('/rebalance', methods=['POST'])
def rebalance():
data = request.json
current_allocation = data['current_allocation']
target_allocation = data['target_allocation']
# Fetching data from CoinGecko API
api_key = 'CG-k63f6X3RG6T7MGVf6BdfHWh1'
btc_prices = fetch_historical_data('bitcoin', api_key=api_key)
eth_prices = fetch_historical_data('ethereum', api_key=api_key)
# Preprocessing data
btc_sequences, btc_targets, btc_scaler = preprocess_data(btc_prices)
eth_sequences, eth_targets, eth_scaler = preprocess_data(eth_prices)
# Build and train model
btc_model = build_lstm_model((btc_sequences.shape[1], btc_sequences.shape[2]))
eth_model = build_lstm_model((eth_sequences.shape[1], eth_sequences.shape[2]))
# Training BTC model with progress bar
for epoch in tqdm(range(10), desc="Training BTC Model"):
btc_model.fit(btc_sequences, btc_targets, epochs=1, batch_size=32, verbose=0)
# Training ETH model with progress bar
for epoch in tqdm(range(10), desc="Training ETH Model"):
eth_model.fit(eth_sequences, eth_targets, epochs=1, batch_size=32, verbose=0)
# Predict prices using the trained models
btc_predicted_price = predict_price(btc_model, btc_sequences, btc_scaler)
eth_predicted_price = predict_price(eth_model, eth_sequences, eth_scaler)
# Log the predicted prices to ensure they're being generated
print(f"Predicted BTC Price: {btc_predicted_price}")
print(f"Predicted ETH Price: {eth_predicted_price}")
predicted_prices = [btc_predicted_price, eth_predicted_price]
# Rebalance portfolio
adjustments, rounded_predicted_prices = rebalance_portfolio(current_allocation, predicted_prices, target_allocation)
return jsonify({"adjustments": adjustments, "predicted_prices": rounded_predicted_prices})
if __name__ == '__main__':
app.run(debug=True)
Step 5. Run the Application
- Run
app.pyto start the Flask server backend. - Open
index.htmlin your browser to open the front end: - Enter your portfolio details and target allocation percentages, and click “Rebalance Portfolio.”
- View results: The UI will display the rebalancing suggestions based on your input and the AI’s predictions.
