Brokerage with Order Queueing

[tmcdonough10]

My system gives me multiple signals after the market closes on day 0, with a limit buy price for the following day (day 1). Each signal calls for between 10-15% of current equity, and I will often get in excess of 10 signals.

Does anyone know of a brokerage that allows me to rank these trades so that my brokerage will not execute stock XYZ, for example, until stocks ABC, DEF, and GHI have been executed? I would assume this would be an order "queue" of some sort.

Any advice appreciated.

Thanks
