1 financial engineering 2 insurance major 3 accounting. In fact, I feel that any engineering+mathematical accounting can do quantitative transactions: for example, how to quantitatively convert wheat, corn and pork? First, you need to find an agronomist to calculate the probability of yield per mu, then you need to find a biologist to calculate the digestibility of nutrients and the rate of meat production, and finally you need to find a finance to calculate the best input-output ratio. Such a quantitative transaction is completed. Personally, the derivative indicators related to volume and price are strictly technical indicators. Many people simply equate KDJ, MACD, EMA, William indicator and other indicators with narrow technical analysis. But if I ask these questions here, people may have different ideas: Is VAR a technical indicator? Is BS a technical indicator? Do GARCH, ARMA and SV count as technical indicators? Are the models of various filtering transformations in physics technical indicators? Is the classic Lee-Ready algorithm in high frequency a technical index? In fact, all the above can be technical indicators, but some are relatively simple and some are more complicated. Even if all kinds of stochastic processes and nonlinear models are introduced, as long as they are based on quantity and price, aren't they technical indicators? The world's largest CTA Winton and the second largest AHL have developed to the present, and the technical indicators in their models are still very important sources of alpha. Whether technical indicators are useful or not, there will be completely different views on different quantitative fields. First of all, for statistical arbitrage, there is a special alpha from volume and price analysis. According to the practical experience of a friend who worked in world quant, this alpha can still have a place in the highly mature American market. Secondly, isn't cointegration regression a technical indicator of various arbitrage strategies? Isn't the most classic price difference SD a technical indicator? Finally, back to CTA, it can be said that most of these strategies are technical indicators. Of course, the data sources of CTA funds have become more and more diversified, including spot data and macro data. But even so, the strategy of quantity and price still accounts for a large proportion.
