Dark Ice Algo

Create a PDF of this page to save or print.


Similar to an iceberg or reserve order, Dark Ice lets you specify a display size different from the order size that is shown in the market. Additionally, the Dark Ice algo randomizes the display size +/- 50% and, based on the calculated probability of the price moving favorably, decides whether to place the order at the limit price or one tick lower than the current offer for buy orders and one tick higher than the current bid for sell orders.

User Inputs
