### Create Live Algorithm
# Define placeholder IDs for compilation and node (replace with actual values)

    "projectId": project_id,  # ID of the project to deploy as a live algorithm
    "compileId": compile_id,  # Compilation ID for the algorithm code
    "nodeId": node_id,  # Node ID where the algorithm will run
    "brokerage": {  # Brokerage configuration for live trading

### Read Live Algorithm Statistics
# Prepare data payload with project and deploy IDs to fetch statistics

### Liquidate Live Algorithm
# Prepare data payload with project ID to liquidate the algorithm

### Stop Live Algorithm
# Prepare data payload with project ID to stop the algorithm

### List Live Algorithms
# Prepare data payload with filters for listing live algorithms
