GBGreen Is My Favorite Color Portfolio123 is unique in that the tools are in front of you. Tools that are simple enough to manipulate to attain an outcome of performance. Yes I would recommend this software to anyone who is ambiguous and want results in the stock market.

GBscreens work ..get back testing or you… screens work ..get back testing or you will not really know what is best. Probably need a month or two of back-testing to get things tested and tuned for your needs. that's the Basic Public Screen plus testing them with the different Setting/Ranking methods is a lot of combinations to start from. Then you can tweak for bad /good market situations.

DEVery flexible stock screening and backtesting platform This is the best and most flexible platform for stock and ETF screening, ranking and backtesting I know. With main focus on fundamentals, you can test, combine and vary hundreds of parameters. No programming knowledge required. One restriction: Portfolio123 does not support intraday trading.

GBHighly recommended They make a great product and offer a good service. They are responsive. It takes time to learn their tools and how to navigate their website which is no different than any other comparable site except that you are doing far less coding from scratch and more actual thinking and developing trading models.
