I am curious about what the possible advantages would be to programming an HFT trading app.
Any pre designed software has an update time of about 45 sec.
If you made a scalping app, continuously playing the spread, buy low/sell high, always picking up nickles and dimes, what would be the advantages or disadvantages?
I see algorithmic trading on Cryptsy all the time, but none appear beefed up for speed.
If you are trying to build a HFT app then you are doing it wrong. If you are going to try to "HFT" then you will need to invest in infrastructure that is physically located very close to the data center/trading engine of a major exchange. This would allow you to get information the exchange is providing sooner then other market participants
