As you know, I'm the FSB Pro author, and my opinion is highly subjective, so better ask in some forum for a neutral opinion.

StrategyQuant is something like an entry-level for FSB Pro and EA Studio. 90% of our users come from SQ.

Both programs are valuable but different.

StrategyQuant is mainly used for creating a set of strategies automatically. You just run it, and after two days, you have strategies. It is designed to produce good backtest result without paying attention to the strategy logic. SQ may create a strategy that trades when MACD is higher than RSI, for example. It is a little bit like comparing apples with oranges.

I can tell you more for FSB, of course.

We invented the strategy Generator in 2004, the backtesting interpolation methods, the Method Comparator, the Ambiguous bars and others.

FSB was free and open-source until 2014.

FSB aims to provide tools for creating a logically correct strategy and present all aspects of the backtest to the trader. FSB users can create complex strategies manually. FSB provides a possibility to set individual symbol and data period for each indicator. It provides signals shift and signal repeat functions, which gives the possibility of creating complex signals. There are also logical groups.

FSB has a Bar Explorer tool that shows all executed and cancelled orders and positions in data tables and graphs. This is the only way to understand how the backtest works.

SQ is better if you want a bunch of strategies and don't care how they trade.

FSB is better if you want to create logically correct strategies and understand how automatic trading works.

Historically, FSB was free and open-source when Mark created SQ as the first commercial strategy generator. The serious guys like you turned to FSB Pro and EA Studio after we also started commercial service.

I'm very proud that many SQ clients use our programs. And even more, I'm not aware of even one case of a user switched from FSB Pro to SQ :) (A yes, I'm absolutely biased, as you see.)

We also put great efforts to improve our online platform EA Studio, and it becomes better and better.

Most of the traders find benefits to use both programs, and that's why our packs are accepted very well.

A great part of the people who buy FSB Pro already own SQ. If you own SQ, too, we can offer you a 25% competitive tool user discount. Please contact us for an offer.

However, if you don't have SQ, we are pleased to offer you EA Studio. EA Studio is very easy to start with and will provide you with fast, logically sound strategy creation. We see EA Studio as better than SQ in many ways because it offers you a fully automated workflow with its Reactor tool, creates thousands of strategies per minute and lets you do and learn much more.

EA Studio also comes as the perfect stepping stone to continue editing and analyzing strategies in-depth with FSB Pro.
