Why do traders still need 5+ different tools?

While building Stryker Trading Academy, one problem kept standing out to me.

Traders are constantly jumping between different platforms for education, charting, indicators, backtesting, journaling, market analysis, and community.

We’re trying to bring that entire workflow into one place, so a trader can learn a strategy, test it, trade it, track the results, and improve without constantly switching tools.

I’m curious how other traders and builders see this.

If you trade, what tools are currently part of your daily setup? And if you could combine everything into one platform, what would be absolutely essential?
