Please Do NOT distribute this presentation Glossary Systematic strategies o “Algo-trading” = “Algorithmic trading”; A trading machine that generates trading signals (i. e. , decisions: “buy”, “sell”, “short”, “cover”, “add more”, “reduce”, “drop” etc. ) based on a well predefined set of rules and criteria; In many cases, “algo-machine” means also that orders are sent, tracked and handled automatically (no middle man) o “Quant-trading” = “Quantitative trading”; An “algo” machine that generates its trading signals based on quantified parameters which in many cases are meaningless for traditional economics o “Systematic-trading” = all kinds and types of trading machines which generate their trading signals based on a well predefined set of rules and criteria; no discretionary decision is allowed !
