Domain distillation
The perfect place to keep an eye on what we learned during our SOR journey.
-
We distinguish two kind of Smart Order Routing system:
-
Historical SOR: receives orders to be executed as inputs (from human Traders, Order Management Systems, Hedging Systems), and splits them into several limit orders on various execution venues to ensure their best execution (via order execution strategies)
-
Modern/Adaptive SOR: receives investment intentions (e.g. I want to sell all my apple stocks, but only if the price is above ...) as inputs, and translates them into orders that will be then executed through the best possible execution strategies. A Modern/Adaptive SOR must also provides audit trail for every execution in order to prove best execution if requested by the financial regulators (see. the MIFID directive).
-
Somehow, a SOR is like a broker (giving the illusion of a single execution venue to the investor(s), whatever the number of used execution venues.
- Investor's intentions / objectives
- Execution constraints
- Order Execution modalties (e.g. Immediate or Cancel-IOC, Fill or Kill-FOK)
- Orders triggering conditions
- Execution strategy algorithms. E.g.
- WAP: Waited Average Price
- T-WAP: execute one million every 5 minutes (cuz I want to execute 1M during the next 2 hours)
- V-WAP: volume waited
We have
- T/P (Take Profit) order
- Stop Loss order
- OCO (One Cancels the Other Order) : A combination of T/P order and a Stop loss order (but only one will be executed)
- Entry order: A combination of an 'Entry' (limit) order and an OCO order. The OCO order will be executed only if the 'Entry' order is executed.
- Entry Loop: An Entry Order which triggers the same Entry order when the previous has been executed
The simplest ones:
- Simple Strategy: Targets one market only to execute related order(s)
- Sweep Strategy: Targets multiple markets to execute related order(s) - very common on FX
