The Problem: Fragmented Investment Accounts

Like many investors, I started my investment journey with one broker. But over time, I found myself spreading my portfolio across multiple platforms (Denmark-specific):

  • Nordnet for "Aktiesparekonto".
  • Lunar directly coupled to bank accounts.
  • Jyske Bank presents from relatives.

Sound familiar? If you're nodding along, you've experienced the same frustration I did.

The Daily Struggle of Multi-Broker Investing

Checking my portfolio meant:

  1. Opening 3 different apps
  2. Logging into each platform
  3. Mentally calculating my total portfolio value
  4. Trying to remember which stocks I owned where
  5. Missing the big picture of my investment performance

The worst part? When friends asked "How's your portfolio doing?", I couldn't give a straight answer without pulling out a calculator.

Why Existing Solutions Didn't Work

I tried several portfolio tracking apps, but they all had major drawbacks:

  • Manual entry apps: Required constant updates and were prone to errors
  • Spreadsheets: Time-consuming and couldn't track real-time prices
  • Premium tools: Expensive monthly fees for a simple need

Building the Solution: Stocker

That's when I decided to build Stocker - a simple, free tool that solves this exact problem. Here's what makes it different:

1. Universal Broker Support

Unlike apps that integrate with specific brokers, Stocker works with ANY broker. How? There is no need to link it with anything. You just type in your holdings and Stocker calculates the rest.

2. Real-Time Price Updates

Connect to live market data to see your portfolio value update in real-time. No more switching between apps to check current prices.

3. Portfolio Analytics

  • Total portfolio value across all accounts
  • Individual stock performance
  • Gain/loss tracking

4. Privacy-First Approach

Your financial data stays with you. Stocker doesn't require broker login credentials or access to your accounts.

Who Benefits from Stocker?

After launching Stocker, I discovered I wasn't alone. Here are some common use cases:

  • Company assets tracking assets received at different points in career
  • Active traders using different brokers for different strategies
  • Long-term investors with retirement and taxable accounts spread across providers

Getting Started is Simple

  1. Sign up for free (no credit card required)
  2. Add your stock holdings from each broker
  3. See your complete portfolio in one dashboard
  4. Track performance and make informed decisions
