Hi I want to work in an HFT company or build my own startup for HFT.In codeforces there are many CPers who already work in HFT in companies like Pinely,tower research capital etc.So I want specific guidelines from you guys about what knowledge and skills I need to get into HFT.And to build my own startup how much investment and what hardwares do I need?My query is of two types:

• What abilities do I need to get into HFT?

• How much investment and hardware is needed to build an HFT?

If any of these two questions gets answered I will be very happy,Thank you
