Portfolio123 is a game-changer for… Portfolio123 is a game-changer for stock investors, providing a powerful platform for the design, simulation, and deployment of quantitative financial models. It also has stock screening, charting (including YChart style), trading (via Interactive Brokers and Tradier), macro economics charting, watchlists, an earnings center, cross-section series plotting, external data importer, a data API, stock news, stock summary snapshots, stock comparison tool, sector/Industry performance, fundamental and estimate summaries, a user forum and more (really). In the near future, machine learning will be supported. It's not just another retail-level tool; it's the only one that I’ve found to work in practice. To find something better, I suspect you'd have to go professional and spend significantly more. I've been a loyal subscriber for over a decade, which speaks volumes about its effectiveness. Is there a downside? Sure, building successful trading models is hard work, but with dedication and focus, it's possible to be successful. Whether you're researching stocks, building and simulating quantitative models, or managing accounts, Portfolio123 has what you need.

Great Tool Great Tool, great team, great support. I am a very satisfied user for 9 years. I have spent countless hours on it. Only concern: their are dependent on data providers policies. It may occasionally result in changing data or pricing. Backtest servers are much faster and more reliable than in 2 other similar platforms I have tried.

Extremely powerful and unique tool Extremely powerful and unique tool. Im not aware of any other like it on the market. Despite having no formal finance background I have decisively beaten my benchmark index for multiple years with real money investing in companies that are off most other people's radar. Once you get used to systematically investing with a model you will wonder how you did it any other way (or how you could do it any other way). The staff is extremely knowledgable and responsive. The user community is generous and supportive. Beyond that, the tool is just fun to research, test theories and play around with.
