This paper proposes a method to give an early warning of an abrupt change of price in a foreign exchange market. Volatility is a quantification of how much a value moves in a time series. It is now customary to assume that volatility of foreign exchange markets is time-varying. Intuitively we observe that there are at least two states or regimes: one is with low volatility and the other is with high volatility. Under high volatility regime, there are chances of high returns but with very high risks. For many nonprofessional traders, the high volatility regimes are periods that they loose with high probability. We believe that giving an early alert of starts of high volatility regimes is beneficial for many nonprofessional traders and for the foreign exchange markets. There are many studies to predict volatility of foreign exchange market by using ARCH or GARCH model with possibly hidden Markov model to represent regimes. We, though, focused on prediction of volatility levels by using machine learning techniques so that we get a good prediction. We particularly focused on support vector machine that learns sequences of volatility levels estimated by hidden Markov model and makes prediction of the level. We performed numerical experiments on real data and obtained good performance.
