I’m a 40-year-old software developer inspired by Principles by Ray Dalio. If you haven’t yet read this great book, I strongly recommend it even if you aren’t a trader.
I became an independent software vendor back into 2005, starting with internet marketing tools, then gradually moved to trading niche. I trade from time to time but it’s more fun for me to develop trading tools for my personal use.
There are a lot of ideas under development but the only tool I’m happy enough to publish is Forex Simulator – one of the best and fastest trading simulators. I optimized it for manual backtesting, learning and training.
