The simple-copy strategy uses the mid-price (the middle price between the best ask and best bid of the orderbook) of a source orderbook and generate an orderbook using a predefined or custom pattern. The depth of the created orderbook is defined by the number of orders in each side with the levels_count parameter and the price difference between orders with the levels_price_size parameter.
Orders amount are set according to the source orders volume of the same price level.

The copy strategy uses a source exchange market to create an orderbook on a target market. The depth of the created orderbook is defined by the number of orders in each side with the levels_count parameter and the price difference between orders with the price_size parameter.
Orders amount are set according to the source orders volume of the same price level.

This strategy behaves like the Copy strategy and have the ability to order back the liquidity from the source exchange market. An soon as an order is matched, the strategy creates an order on the source exchange with the matched amount and the same price without the spread. This way if the spread configured is higher than the exchanges fee the P&L will be positive.

This strategy copies trades from sources every sampling_ratio trade events. It will trigger a market order with the same amount than the average trades amount being copied in the window. The parameter max_slippage protect against price slippage, it will considere the target orderbook and reduce the amount of the order accordingly to avoid price slippage. A random of 10% is applied on the sampling_ratio to make the strategy not deterministic. The period parameter doesn't affect this strategy since it only reacts on sources trade events.
