Arbitrage type strategies.

Sounds like Swifttrade and their Arbitrage "strategy" hit up an ecn on the ask and bid up to another ECN punch out for your rebate.

Thats a strategy my friends - snickers -
 
Quote from Sparohok:

Arbitrage covers a very wide range of strategies. Pairs trading, merger arbitrage, and other forms of risk arbitrage are often quite accessible to retail traders.

Riskless arbitrage is highly competitive and you generally need to have an edge in execution or resources, as you point out.

yeah i worked at this ATS firm before.
they have around 6 mill of capital and absolute leverage ratio of 100:1. day in and day out doing ETFs. they get new equipments every 3~4 months. but what they do is virtually riskless.
so for retail guys, we can only assume some risk.
 
Quote from QuantDeveloper:

> Now thats an understatement !

You mean it's not simlified enough? :D
No, and stop flattering yourself. If that was the case, that would be an overstatement. :p
I guess the correct term to describe that, ahem..., strategy would be "practically useless".
 
Well, this is just a simplified example that shows how to do basic ATS development with QuantStudio / QuantDeveloper, nothing more, nothing less. The strategy itself works fine and a lot of riskless profits have been earned this way, also with ADR/GDR arbitrage (especially if you sit on BONY/Bloomberg ADR order book :) )

You are right saying that the implementation is far from being perfect (and somewhat useful). The code should be enhanced to

- better manage order states (rejected orders, etc)
- use limit orders to fix arbitrage spread
- use market depth to evaluiate arbitrage volume (though my experience suggests that already the second best bid/ask is rarely tradable in this type of arb).

We actually traded equity/ADR arb a three four years ago and it was 1-3K per day per trader seat per (cross) market (taking into account you use bank infrastructure, depositary and lending).

Cheers,
Anton
