This is my situation exactly. I cannot attest to the efficiency of adaptive algo for limit orders ect. I have only used the adaptive market (patient) on a few of my algorithms which require speed of fill, rather than efficiency of fill as in entry.
I suppose its being patiently impatient. The patient setting only means that the algo scans longer for a better fill but, in most cases it fills in under 2 sec anyways, and that is depending on size and liquidity.
Using adaptive algo on the patient setting with market orders fills better than a regular market order in general. On open, most orders with the patient setting will fill in under 10 seconds if there is adequate liquidity.
