Geometric Brownian motion is used to model stock prices in the Black–Scholes model and is the most widely used model of stock price behavior. Some of the arguments for using GBM to model stock prices are: The expected returns of GBM are independent of the value of the process (stock price), which agrees with what we would expect in reality. 6.4 The Stock Price as a Stochastic Process. Stock prices are stochastic processes in discrete time which take only discrete values due to the limited measurement scale. Nevertheless, stochastic processes in continuous time are used as models since they are analytically easier to handle than discrete models, e.g. the binomial or trinomial process.

The Stochastic Oscillator measures the level of the close relative to the high-low range over a given period of time. Assume that the highest high equals 110, the lowest low equals 100 and the close equals 108. The high-low range is 10, which is the denominator in the %K formula.

Bachelier assumed stock price dynamics with a Brownian motion without drift (resulting in a normal distribution for the stock prices), and no time-value of money. The formula provided may be used to valuate a European style call option. Later on, Kruizenga (1956) obtained the Stochastic Fast plots the location of the current price in relation to the range of a certain number of prior bars (dependent upon user-input, usually 14-periods). In general, stochastics are used in an attempt to uncover overbought and oversold conditions. Above 80 is generally considered overbought and below 20 is considered oversold. Rather than standard price data, it is created by applying the formula of a stochastic oscillator to a set of RSI values. The difference of using the stochastic RSI is that it improves sensitivity and generates a higher number of signals than the traditional indicator. You can calculate stochastic RSI by using this formula. Having financial market with safe rate r and risky asset S with dynamics under physical measure P $$\frac{dS_t}{S_t}=\mu dt +\sigma dW_t$$ what is the log-stock price? Using Ito formula it is

The next sections deal with concepts such as random walk and Brownian motion. Both processes are conditional to understanding the geometric Brownian motion.

INTRODUCTION It is not difficult to see (using Ito formula) that starting from at time 0, that  A stochastic oscillator is a momentum indicator comparing a particular closing price of a security to a range of its prices over a certain period of time. The sensitivity of the oscillator to market movements is reducible by adjusting that time period or by taking a moving average of the result. The Stock Stochastic Formula The stock stochastic, %K, is a fraction multiplied by 100. The numerator is the current closing price minus the lowest low. The denominator is the highest high minus the lowest low.

Price action refers to the range of prices at which a stock trades throughout the daily session. For example, if a stock opened at $10, traded as low as $9.75 and as high as $10.75, then closed at $10.50 for the day, the price action or range would be between $9.75 (the low of the day) and $10.75 (the high of the day).

This is clearly not a property shared by real-world assets - stock prices cannot be necessary to discuss the concept of a Stochastic Differential Equation (SDE).

We, then, derive a European option pricing formula based on the FSDE model Assume that the stock price follows the fractional order stochastic differential 

Price action refers to the range of prices at which a stock trades throughout the daily session. For example, if a stock opened at $10, traded as low as $9.75 and as high as $10.75, then closed at $10.50 for the day, the price action or range would be between $9.75 (the low of the day) and $10.75 (the high of the day). if the stock price trends upwards and makes higher highs, but the stochastic oscillator does not rise further than its prior highs, that’s a bearish divergence The divergence signals are amplified if %D is above 80 or below 20.
