This is a simple API for testing various trading strategies at Forex market.
It was used at my workshop on a camp called Wakacyjne Warsztaty Wielodyscyplinarne. Workshop was about creating a bot, which trades on Forex market. There, I gave participants possibility to develop and test their ideas in simpler environment, so they could move fast and didn't have to care about details.
