Methods and systems are provided which enable equities broker-dealers to
execute an equity trade order while simultaneously eliminating (or at
least reducing) exposure to the negative consequences associated with
toxic (or likely toxic) orders in the equities market. By using toxicity
and/or profit analyzers, for example, to detect, track and respond to the
level of toxic (or likely toxic) orders present in an equities order
flow, a broker dealer can reduce the level of risk inherent in serving as
counter-party to order flows, such as anonymous equities order flows.
Various alternative embodiments are also disclosed.
