Can individuals day-trade stocks using High-Frequency Trading (HFT)?
Nobody is going to stop you if you want to try that. But you should keep in mind that you have to invest a lot in getting the best hardware you can lay your hands on, best fail-safe connectivity to the exchanges, best trading algorithms and software that money can buy and loads of other stuff. This all needs quite a big amount of upfront investment without guaranteeing returns. That is why you see institutions with deep pockets i.e. banks and trading firms only involve themselves in HFT.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
