Machine Learning Operations: A Strategic Solution to Prevent Failed Trades and Safeguard Revenue (V 1.2)
Failed trades continue to be a major pain point for broker-dealers, with trade settlement failures impacting revenue, operational efficiency, and regulatory compliance. Common causes of these failures include insufficient securities availability, securities on loan that are difficult to recall, poor market liquidity, client behavior, inaccurate/incomplete reference data, plus more.
In today’s fast-paced financial markets, ensuring seamless trade settlement is critical for minimizing risks and maximizing profitability. By leveraging machine learning and scalable, real-time data infrastructure, financial institutions can handle large volumes of trade data, reduce settlement failures, and optimize operations.
Part 1: Create and Train the Machine Learning Model
To handle the complex nature and vast scale of trade data, the model used here is a random forest classifier, a tree-based machine learning approach that builds multiple decision trees and combines their outputs to make more accurate predictions. Random forests are ideal for detecting non-linear relationships and feature interactions, making them well-suited to high-stakes, multi-dimensional data.
In our example, the random forest model uses key trade attributes—such as trade size, asset type, counterparty information, liquidity, and previous settlement history—to predict the likelihood of trade failures. This setup leverages data from supplementary systems, enhancing the model’s accuracy and reliability by drawing on broader insights.
Step 1: Create and Train the Machine Learning Model
What it does:
This step simulates large-scale trade data and trains a random forest model to predict the likelihood of trade failures. You can connect your data here as well. Make sure you are preprocessing your data before training your ML model. The process of data preprocessing helps ensure that the model learns effectively, avoids bias from skewed data, and achieves more accurate predictions.
Business value:
By predicting failed trades early, broker-dealers can take preemptive action to fix potential issues, ensuring smoother settlements, reducing operational risk, and protecting revenue from losses associated with failed trades.
Here’s the Python code for creating and training a machine-learning model to predict failed trades. This is the core of the solution:
```python
import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score
import joblib
# Generate sample data with additional features
def generate_trade_data(n_samples=1000000): # Simulating a large dataset, you can add your own data sources.
np.random.seed(42)
data = {
'trade_size': np.random.uniform(1000, 1000000, n_samples),
'asset_type': np.random.choice([1, 2], n_samples), # 1: Stock, 2: Bond
'counterparty': np.random.choice([1, 2, 3], n_samples), # Clients
'time_to_settle': np.random.choice([1, 2, 3], n_samples), # Days to settle
'liquidity': np.random.choice([1, 2, 3], n_samples), # 1: Low, 2: Medium, 3: High
'prev_settlement_history': np.random.uniform(0, 1, n_samples) # Settlement success rate
}
# Label 'failed_trade' based on realistic trade failure conditions
data['failed_trade'] = np.where(
(data['trade_size'] > 800000) & (data['liquidity'] == 1) | # Large trades with low liquidity
((data['time_to_settle'] == 3) & (data['asset_type'] == 2)) | # Bonds with long settlement time
((data['counterparty'] == 3) & (data['trade_size'] > 500000)) | # High-risk counterparty with large trades
(data['prev_settlement_history'] < 0.3), # Low settlement history success
1, 0
)
return pd.DataFrame(data)
# Train the random forest model
def train_trade_model():
df = generate_trade_data()
X = df[['trade_size', 'asset_type', 'counterparty', 'time_to_settle', 'liquidity', 'prev_settlement_history']]
y = df['failed_trade']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Initialize and train a random forest classifier
model = RandomForestClassifier(random_state=42, n_estimators=100, max_depth=10) # Optimized for large datasets
model.fit(X_train, y_train)
# Display accuracy for testing purposes
predictions = model.predict(X_test)
print(f'Accuracy: {accuracy_score(y_test, predictions):.2f}')
return model, df
# Save the model for later use
model, df = train_trade_model()
joblib.dump(model, 'trade_reconciliation_model_rf.pkl')
This model can predict failed trades by analyzing patterns in historical data, allowing broker-dealers to anticipate and prevent potential issues.
Step 2: Deploy the Model via API with Flask
What it does:
This step deploys the trained model as a real-time API using Flask, allowing broker-dealers to receive instant predictions on trade failure risk. The API takes trade details as input and returns a probability of failure for each trade.
Now that the model is trained, the next step is to deploy it using a Flask API. This API will enable real-time predictions of trade failures.
```python
from flask import Flask, request, jsonify
import joblib
import numpy as np
app = Flask(__name__)
# Load the pre-trained model
model = joblib.load('trade_reconciliation_model_rf.pkl')
@app.route('/predict', methods=['POST'])
def predict():
data = request.get_json()
input_data = np.array(data['features']).reshape(1, -1)
prediction = model.predict(input_data)
probability = model.predict_proba(input_data)[0][1] # Probability of failure
result = {
'failed_trade': bool(prediction[0]),
'failure_probability': probability
}
return jsonify(result)
if __name__ == "__main__":
app.run(host='0.0.0.0', port=5000)
Part 2: The Scalable Infrastructure
Handling billions in transactions and high data volumes requires robust infrastructure. By using Docker and Kubernetes, we ensure that the model operates reliably and scales dynamically as trading volumes fluctuate. This approach is considered MLOps (Machine Learning Operations), where machine learning models are seamlessly integrated into a production environment with DevOps principles to ensure stability, scalability, and continuous deployment.
Step 3: Dockerize the Model
What it does:
Dockerization means packaging the entire machine learning application (model + API) into a self-contained unit (a Docker container). This container includes everything needed to run the model, such as software dependencies, ensuring that it runs consistently no matter where it’s deployed.
Business value:
Docker allows you to easily deploy the model across different environments (e.g., testing, staging, production) without worrying about compatibility issues. This ensures reliability and allows the model to be quickly moved into production, where it can make a real impact by preventing failed trades.
To make the model portable and scalable, we will containerize it using Docker. Here’s the Dockerfile that packages the Flask app and the model:
```docker # Use an official Python runtime as the base image FROM python:3.9-slim # Set the working directory inside the container WORKDIR /app # Copy the requirements file to the working directory COPY requirements.txt . # Install dependencies RUN pip install -r requirements.txt # Copy the entire app to the working directory COPY . . # Expose the port that the app runs on EXPOSE 5000 # Run the application CMD ["python", "app.py"]
You can then build and run the Docker container using the following commands:
Build the Docker image:
```bash docker build -t trade-reconciliation-api .
2. Run the Container:
```bash docker run -p 5000:5000 trade-reconciliation-api
Step 4: Deploy to Kubernetes for Scalability
What it does:
In this step, we deploy the Docker container with the machine learning model to Kubernetes, a platform that manages and scales applications. Kubernetes allows the system to automatically adjust the number of containers running the model depending on trade volumes (i.e., more containers during busy times and fewer during quiet periods).
Business value:
By using Kubernetes, the business ensures that the model can handle high volumes of trade data, especially during peak trading hours. This automatic scaling ensures that predictions can be made quickly and reliably, reducing the likelihood of trade failures slipping through due to system overload.
The key to preventing failed trades at scale is deploying the model on Kubernetes, which provides automated scaling and fault tolerance.
Kubernetes Deployment YAML (ml-deployment.yaml):
```YAML
apiVersion: apps/v1
kind: Deployment
metadata:
name: trade-reconciliation-deployment
spec:
replicas: 4 # Increased replicas for higher volume
selector:
matchLabels:
app: trade-reconciliation
template:
metadata:
labels:
app: trade-reconciliation
spec:
containers:
- name: trade-reconciliation
image: trade-reconciliation-api-rf:latest
ports:
- containerPort: 5000
2. Kubernetes Service YAML (ml-service.yaml):
```YAML
apiVersion: v1
kind: Service
metadata:
name: trade-reconciliation-service
spec:
selector:
app: trade-reconciliation # This matches the label used in the Deployment YAML
ports:
- protocol: TCP
port: 80 # The port to expose outside the cluster
targetPort: 5000 # The port the container listens on inside the pod
type: LoadBalancer # Exposes the service to the external network (e.g., public IP on cloud providers)
Step 5: Deploy the Model to Kubernetes
What it does:
This step involves creating a service in Kubernetes, which exposes the model to the outside world via a network port. It makes the machine learning model accessible to other systems (e.g., your trading platform, OMS, etc) that need to send trade data and get predictions.
Business value:
By making the model accessible via a Kubernetes service, the firm can integrate real-time trade failure predictions into its broader trading operations. This helps prevent failed trades across all systems that connect to the prediction service.
1. Deploy the model:
```Bash kubectl apply -f ml-deployment.yaml
2. Expose the Service:
```Bash kubectl apply -f ml-service.yaml
Note: Integrating Supplementary Systems for Broader Data Ingestion
To optimize this solution further, broker-dealers can integrate supplementary systems used in pre and post trade activities. This broader data ingestion allows the model to process additional contextual data (e.g., securities lending statuses, market liquidity, counterparty risks) that can enhance predictive accuracy and generate more impactful business intelligence.
These supplementary systems can feed real-time data into the infrastructure, providing the operations team with a holistic view of trade activities and potential settlement risks.
