1) Hidden orders widely available, sometime called Iceberg 2) Trailing limit and stop orders available, with IB at least. 3) Do you know of any possibility of placing hidden trailing limit orders, using 3rd party APIs or else? Thank you
I have done a lot of work since posting this yesterday. It seems that Relative/Pegged-to-Primary orders are what I am after. Would anyone know how to set things up using Extended Order Attributes to execute Relative orders in the IB new socket based DDE spreadsheet?
