Quote from Pekelo:
Since I missed my Triangulation 101 class can someone tell me:
1. As I am closer to London, I am getting farer from NYC and vica versa. So I don't really see the advantage of this optimum point. The distance between 2 points is still going to be the same. Maybe trading 3 or more exchanges has an advantage, but I don't see it with 2 cities only.
2. I thought wired trading was still the fastest. How do they trade wired from a boat? Or can via satelite be faster???
I presume boats would be wired to underwater fiber.
Let's assume latency from (A, NYC) to (B, London) is 6ms.
You're trading a stock and monitoring PriceA and PriceB.
If you're only trading on one exchange or the other, I think you're right about there being no benefit. You'd make your trading decision 3ms faster than anyone at either exchange, but it would still take 3ms for your order to reach the exchange.
However, if you need to trade on both exchanges, the midpoint is the best place to make your decisions. Also should be a good place for an exchange itself if they want to suck volume from the geographically disparate ones.
I believe once an exchange is set up in the ocean, though, and takes any significant volume, that all the normal exchanges will just cluster together and consolidate. Just seems more trustworthy to me.
Though, sometimes I think my orders are lost in the Bermuda Triangle already..
