New Strategy Features with Avellaneda Market-Making

order_levels

  • A new strategy command that can be initiated when parameters_based_on_spread = true.
  • The order size of the level will be equal to order_amount the spread between the orders will be calculated based on the max_spread, and the new orders related to order levels will be created between the first order and max_spread, distributed exponentially.
  • When parameters_based_on_spread = false, the behaviour of order_levels will be similar to pure_market_making

order_override

If you prefer manual control of orders rather than bot calculated order_amount and order_level_parameter, manually set order value of buy/sell, order spread, and order amount with order_override.

You can only set the order_override in the strategy config file you created.
