Quantitative analysis forex
The trader analyzes the history and finds patterns. Force majeure and other fundamental factors are automatically taken into account in the general trend. But there is another trading method that does not involve either technical or fundamental analysis. For it, predicting the direction of the trend is a secondary issue, and the releases of the Central Banks are irrelevant.
Currency quotes here are just a set of basic input market data on which the network machine algorithm is built. This method is called quantitative trading strategy or quant based trading strategy. The point of quants trading strategies is not to predict the direction of the trend, but to find the optimal strategy and the best set of trading tools by selecting a mathematical set of parameters that will ultimately allow you to get a stable profit. Despite seeming somewhat pointless, algorithmic trading and quantitative strategies have been known for more than half a century and actively used by investment hedge funds.
One of the first companies to apply quant based trading strategies was the George Soros Foundation. Soros was able to prove in practice that fundamental and technical analysis are inferior in comparison with the strength of capital. This is why his fund was one of the first to give up assessing the monetary policy of the Central Bank and searching for technical patterns in favor of mathematical modeling and programming.
In , Fischer Black and Myron Scholes first published the option pricing model formula. The key point in determining the value of the option was the expected volatility of the underlying asset, the level of which can be calculated mathematically. Without going into details, the formula includes the cumulative distribution function of the standard normal distribution, the risk-free interest rate we see something similar in the Sharpe ratio , spot and strike prices, and volatility.
To characterize the sensitivity of the option price to changes in certain values, coefficients called greeks based on the letters of the Greek alphabet are used. In , the Black-Scholes model won the Nobel Prize in economics, radically changing the approach to developing trading strategies. Today's real examples of using quantitative trading models are:. Two Sigma Investments - the fund was founded in Its trading strategies are based on methods using artificial intelligence, machine learning an analogue of neural networks , and distributed computing. The company is known for its development of sophisticated modeling systems and programs that track market anomalies.
Quantitative Trading Definition
Renaissance Technologies LLC - the company was founded in It specializes in trading in quantitative models developed on the basis of mathematical and statistical analysis. Quantitative trading is based on the principle "the more the better". The data obtained are interpreted as follows:. As a function. The job of the programmer writing the model code is to find this very function to build an equation that would describe the distribution of quotes in a time series. As a time series that is analyzed by statistical methods. The accuracy of forecasting by statistical regularity is tested on other time intervals forward testing.
The quantitative trader can get some extreme points from the function and time series that describe the price movement chart. By adding an additional mathematical apparatus approximation, entropy , you can calculate the areas of trend slowdown, flat, or calculate the predicted stop order points. And only later a quantitative trader may try the strategy in real time, applying the risk management required. Another method of econometric analysis on which quantitative trading strategy is based is to break the time section into separate clusters areas where you can see a clear price movement according to a certain pattern.

For example, a section 10 years long, is divided into segments of different lengths 1 day, 1 week - they do not have to be the same , on which the pattern is visible. Moreover, the sections can intersect and overlap each other - a neural network with algorithmic program code finds all these sets of patterns.
The current market conditions are compared with similar patterns of price behavior in the past, based on which a further forecast is made. High liquidity. Only highly liquid instruments are selected for quantitative trading strategies, therefore this method is more common on stock markets than on Forex.
How to set up a Quantitative Trading Market Data Repository
Quant trading strategies involves launching mathematical algorithms for a large number of instruments. It will not work on one currency pair. In this case, the correlation coefficient between instruments should be as low as possible. Quantitative analysis works for the largest possible number of algorithms three variants of such algorithms - function search, distribution of number series and template trading - are described above.
Vendor environment approach
The model of quantitative strategies has something in common with the algorithmic advisor trading. The formula of moving averages attempts to search for patterns of price movement. And over time, technical analysis enthusiasts added a series of coefficients to the formula, which became EMA, LMA, etc. Still, forex quantitative trading is not the Grail, but just another trading method.
