ChainSweeper

ChainSweeper is a system that we developed for our own trading analysis purposes, because such a product did not exist in the marketplace. The development has now reached a point that it can be prepared to be made available to the public as a web-based platform. It is a very easy to use UI, with immediate feedback, offering back testing and historical visualizations for option and stock positions and spreads. The interface is devised in such a way that it is impossible to enter an invalid position or spread. ChainSweeper is software that we use successfully ourselves, in support of options trading. It fills a big hole in the marketplace for retail traders: the only similar product is ThinkBack, a component of TDA's ThinkOrSwim. But ThinkBack is tedious and inflexible. Our results agree with ThinkBack, and is at least 10 times as fast to use. And it has a much larger feature set for manipulating positions and spreads.
