In order to measure the performance of your strategy, create one on the dashboard. It is important to use the access token linked to the strategy as this is the only way to measure the performance of the strategy.
If you want to take part in the trading competition (and get money as reward if you take one of the first places) you have to make your strategy public.
Nobody knows what happens inside your strategy (e.g. no orders will made public), only the overall performance will be shared with everyone.
