Love the screening with backtests Love the screening with backtests. Forum members are very helpful. Would like access to more foreign markets, log charts, and ability to trade with entry and exits at the $100/mo level.

Since 2011 this is my main modeling platform - no regrets I have been using this platform since 2011. I have used others, even ones that cost 6-digits per year to license and I can honestly say I prefer this one. I have used ClariFI and WorldQuant to name just 2 of the high institutional grade platforms and about 6 others. The P123 simulation engines are lighting fast, they listen to users and are always adding new features...in fact...after 9 years of using the platform I still probably use only 20% of what it can do. A well-rounded system whether you are running simple screens, custom weighed complex portfolios or in-depth research. Any serious family office or smaller firm should take the time to get one of their guys trained on this platform.

Excellent site for backtesting equity trading strategies Excellent site for testing stock and ETF trading strategies. P123 provides a thorough point-in-time database with a powerful and flexible engine to simulate backtests of systems. And they integrate with Interactive Brokers to automate applying those strategies to live trading.

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.

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.
