Stochastic Oscillator
The Stochastic Oscillator Technical Indicator compares where a securitys price 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） closed relative to its price range over a given time period. The Stochastic Oscillator is displayed as two lines. The main line is called %K. The second line, called %D, is a Moving Average of %K. The %K line is usually displayed as a solid line and the %D line is usually displayed as a dotted line.
There are several ways to interpret a Stochastic Oscillator. Three popular methods include:
- Buy when the Oscillator (either %K or 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） %D) falls below a specific level (for example, 20) and then rises above 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） that level. Sell when the Oscillator rises above a specific level (for example, 80) and then falls below that level;
- Buy when the %K line 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） rises above the %D line and sell when the %K line falls below 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） the %D line;
- Look for divergences. For instance: where prices are making 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） a series of new highs and the Stochastic Oscillator is failing to surpass 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） its previous highs.
Calculation
The Stochastic Oscillator has four variables:
- %K periods. This is the number of time periods used in the stochastic calculation;
- %K 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） Slowing Periods. This value controls the internal smoothing of %K. A value of 1 is considered a fast stochastic; a value of 3 is considered a slow stochastic;
- %D periods. his is the number of time periods used when calculating a moving average of %K;
- %D method. The method (i.e., Exponential, Simple, Smoothed, or Weighted) that is used to calculate %D.
The formula for %K is: %K = (CLOSE-LOW(%K))/(HIGH(%K)-LOW(%K))*100
Where:
CLOSE is todays closing price;
LOW(%K) is the lowest low in %K periods;
HIGH(%K) is the highest high in %K periods.
The %D moving average is calculated according to the formula: %D = SMA(%K, N)
Where:
N is the smoothing period;
SMA is the Simple Moving Average.
Parabolic SAR
Parabolic SAR Technical Indicator was developed for analyzing the trending markets. The indicator is constructed on the price chart. This indicator is similar to the Moving Average Technical Indicator with the only difference that Parabolic SAR moves with higher acceleration and may change its position in terms 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） of the price. The indicator is below the prices on the bull market (Up Trend), when its bearish (Down Trend), it is above the prices.
If 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） the price crosses Parabolic SAR lines, the indicator turns, and its further values 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） are situated on the other side of the price. When such an indicator turn does take place, the maximum or the minimum price for the 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） previous period would serve as the starting point. When the indicator makes a 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） turn, it gives a signal of the trend end (correction stage or flat), or of its turn.
The Parabolic SAR is an outstanding indicator for providing exit points. Long positions should be closed when the price sinks below the 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） SAR line, short positions should be closed when the price rises above the 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） SAR line. It is often the case that the indicator serves as a 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） trailing stop line.
If the long position is open (i.e., the price is above the SAR line), the Parabolic SAR line will go up, regardless of what direction the prices take. The length of the SAR line movement 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） depends on the scale of the price movement.
Calculation
Where:
SAR(i-1) is the value of the indicator on the previous bar;
ACCELERATION is the acceleration factor;
EPRICE(i-1) is the highest (lowest) price for the previous period (EPRICE=HIGH for long positions and EPRICE=LOW for short positions).
The indicator value increases if the price of the current bar is higher than previous bullish 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） and vice versa. The acceleration factor (ACCELERATION) will double at the same time, which would cause Parabolic SAR and the price to come together. In other words, the faster the price grows or sinks, the faster the indicator approaches 如何在Metatrader 4 (MT4)中设置抛物线转向指标（SAR） the price.
