Silly assertion.

Absolutly, 2000 iterations with 3 variables on 81000 records : 10 secondes.(On a 2.7 Gz) If one wants speed, one have to get a formula 1, not a truck. And speaking about real time financials apps, Sql stuffs on PCs are trucks, they are only suitable with mainframes and/or paralell computing.

C++ flat binary file by far. Less code optimized for speed and no additionnal lib or dll to implement and all the stuff. But it's only a small part of the applications(graphs, systems, ATS...).

Going to be the Witt report :p

I agree completely. And on the US markets, i prefer trading the YM(now there is more liquidity) for the same reasons. The Esignal feed is not very good for Europeans markets, especially after the opening of the US markets. Trade with IB feed-API, it's fine for me.

Do you trade from the us or from europe?
