The essence of high frequency trading is to quickly move in and out of several short term positions. By quick, we mean milliseconds – something that is humanly​.

Risk and compliance are separate functions from trading. Otherwise a screwed up trader tends to hide things under the rug until the company goes bust. Fair enough, as an independent check although I would prefer if the computer system didn't offer the possibility for a trader to do anything covert. What I was getting at, though, is that every trading decision, ideally, should take constraints such as risk and legal compliance into account anyway.

It's a unique position with unique set of skills, you will not see hordes of them listed like software engineers or DBAs.

However, idiosyncratic jumps in the tail factor lead only to jumps in moments of order three and higher.

These large moves are in part due to jumps in the market index, that lead to co-jumps in all of the risk-neutral moments. However, the majority of large moves occur in the moments of order higher than three, consistent with the idea of jumps in the tail factor.

The existence of the tail factor is further supported by co-jump tests, that reveal co-jumps between the higher order moments that are unrelated to jumps in the market index. The last chapter examines a common assumption of many well known options pricing models: price jumps bear no impact on volatility. To examine the assumption, I analyze high-frequency moves in the market index and in the implied volatility from the options market. The jump regressions indicate a negative correlation between jumps in the market index and changes in the implied volatility.

Potentials of High-Frequency and Algorithmic Trading

The estimates indicate that a market crash of basis points would lead to an increase of basis points in the implied volatility of options.

Speed depends on the available network and computer configuration hardware , and on the processing power of applications software. A new concept is to integrate the hardware and software to form firmware, which reduces the processing and decision making speed of algorithms drastically.

Automating trading

Such customized firmware is integrated into the hardware and is programmed for rapid trading based on identified signals. This solves the problem of time delays and dependency when a computer system must run many different applications. Such slowdowns have become a bottleneck in traditional high-frequency trading. Too many developments by too many participants lead to an overcrowded marketplace.

It limits opportunities and increases the cost of operations. Such trends are leading to the decline of high-frequency trading. However, traders are finding alternatives to HFT.
