One Broker

Broker vs. Investment Bank : The Cost Trap

The methodology strictly dictates the use of a self-directed broker rather than a traditional investment bank, private bank, or active wealth manager.

Traditional investment institutions charge ongoing management commissions (often between 1 to 2% annually) to actively manage your money. Due to the tyranny of compounding costs, a seemingly small 2% annual fee will violently erode 30% to 40% of your total portfolio value over a 20-to-30-year horizon. You are effectively surrendering nearly half your future wealth to a fund manager.

By utilizing a self-directed broker, you bypass this parasitic middleman entirely. You only pay a minimal, one-time brokerage fee - which is often minimal for automated recurring plans - and the internal annual product cost (TER of ~0.17% or less) of the ETF itself. Every single euro remains inside your pipeline to compound for your own future.

Broker Requirements

"Set the rule. Remove the human."

To run an autonomous financial pipeline, your broker must meet our strict requirements. The methodology does not look for active trading features, social feeds, or complex dashboards. We look for safety, real asset ownership, and flawless automation.

1. Absolute Safety (Asset Segregation & Guarantees)

The broker must use strict asset segregation. This means your investments are legally stored in a separate vault, completely detached from the broker's own company balance sheet. If the broker goes bankrupt, their creditors cannot touch your money or your shares. They remain 100% your property.

Additionally, you must ensure the provider is fully regulated and backed by law-enforced government guarantees:
Cash Protection: Any uninvested cash sitting on your account must be covered by an official bank deposit guarantee scheme.
Security Protection: In the extreme and rare case of internal corporate fraud where assets are missing, official investor compensation funds must be in place to cover your losses.

2. Real Asset Ownership (No Derivatives)

The broker must purchase the actual, physical underlying shares of the approved global index in your name. The use of synthetic instruments, CFD trading models, margin accounts, or contract-based derivatives is strictly forbidden. If you do not own the actual fund, you are introducing counterparty risk into the architecture.

3. 100% Execution Automation (Recurring Orders)

You must be able to schedule a fixed monthly money transfer that the broker automatically executes to buy the global index fund (ETF) at a fixed cadence.
If the platform requires you to log in manually every month to click a "buy" button, the process is broken. Manual execution opens the floodgates to emotional hesitation, market timing, and behavioral failure.
