The App invites users to trade scenarios like the collapse of Lehman Brothers, Black Wednesday, or the release of major economic data, and you will be able to react to those events by buying or selling depending on whether you think the market will go up or down The objective of ReTrader is to help you understand how and why markets move, as each scenario is previewed and reviewed by an experienced trader, and you can at all times see the profit or loss of your positions. ReTrader condenses each scenario into short 3-5 minute simulations for you to engage with. Every time you play a game for the first time, we will record your score on a leaderboard where you can compare your performance to other users. ReTraders can enter into global trading competitions or use the APP to keep up-to-date with the current events by choosing to sign up to our subscriptions, which will give you our analysis in the form of mini-games on a weekly basis.
