In our last lesson, we learned about the relative strength index, and different ways that traders use this in their trade. In today’s lesson, we’re going to learn about another momentum oscillator, which is known as stochastics. So, let’s get started.
I’ll start by saying that there are three different types of stochastic oscillators: the fast stochastic, the slow stochastic, and the full stochastic. All of these operate in a similar manner, however. And when most traders refer to the stochastic, they’re talking about the slow stochastic. So, that’s going to be the focus of this lesson. The basic premise of a stochastic is that prices tend to close in the upper end of their trading range when the financial instrument you’re analyzing is in an uptrend. And in the lower end of their trading range, when the financial instrument you’re analyzing is in a downtrend.
When prices close in the upper-end of their range in an uptrend, this is, obviously, a sign that momentum of the trend is strong, and vice-versa for a downtrend. The stochastic contains two lines, which are known as the percent K line, and the percent D line.
I’m not going to go into the formulas for each, because most charting packages, if not all charting packages that you’ll use, will calculate these lines for you. However, you should know that this is a momentum oscillator. So, when the percent K line is rising, that is an indication that momentum in the market is increasing. And when the percent K line is falling, it’s an indication that momentum in the market is decreasing.
The percent D line is, very simply, a simple moving average of five periods; simple moving average of the percent K line, and it acts to smooth out the price action of the indicator, and slow it down a little bit. And also acts as a signal line for the faster, percent K line, which we’re going to learn about later in this lesson.
It’s a banded oscillator, just like the RSI, so, it fluctuates between 0 and 100. And the upper end of the range is marked by a line at 80. And the lower end of the range is marked by a line at 20. The first way that traders use this is to trade overbought and oversold levels.
George Lane, who invented the indicator, recommended waiting for a cross, back below the 80 line, when the market went from an extremely overbought area before placing a trade to the down side, and waiting for a break, back above the 20 line, before signaling a trade to the upside.
So, you see here, you have the overbought area. You have the break below the 80 line, and then you do have a sell-off that results after that. You have an oversold area here. You have a break back above the 20 line, and then you have a rally.
Again, hindsight is 20/20, and there are going to be false signals with this indicator, as with any other indicator that we’re going to look at. One of the ways to reduce the amount of false signals that you’re going to get is by combining indicators and combining methods of analysis, using some of the things that we’ve learned, so far.
Here you have a false signal. The indicator was in an overbought area, traded back below the 80 line. You did not have a sell-off after that. But hopefully, if you would have watched our lessons on trends and Dow Theory, you would have been watching this strong uptrend here, and you would have not been taken into that trade there to the downside, because there was not a break in that trend line.
Here, however, there was a break at the trend line, and you had, not only, the break of the trend line, which is a very strong signal, but also, the break back below the 80 line of the oscillator. And you did have a sell-off that resulted after that.
A second way this can be traded as crossover signals. Remember from earlier, the percent K line is the faster line. The percent D line is the slower line. So, when the percent K line crosses above the percent D line, this is an indication that it may be a good place to buy.
And when the percent K line crosses below the percent D line, this is an indication that it might be a good place to sell. This is, basically, a way for aggressive traders to catch earlier signals, particularly from overbought and oversold areas.
Here, we’ve got a Bearish cross from our overbought area. We’ve got the Bearish cross with the black line; the percent K line, and trading below the red percent D line. And we’ve got the break below 80 there.
You could have gotten in, however, earlier into the trade, had you been trading the Bearish cross from the overbought area, instead of waiting for the break. But that’s not recommended. And this indicator like the cross of the RSI is very prone to false signals. So, be careful there.
The divergence is the third way. And, very simply, when the market is making new highs, and when the market is trading in the opposite direction of the indicator, that’s an indication that a reversal may be coming. So, you have divergence here, and, as you can see, the market’s making new highs there.
But you can see by looking at the stochastic, that momentum in the market is not following upwards. So, that might be a good place to look for a sell-trade. If you remember from previous lessons, hopefully, you’ll also see something else there, which is a double top.
So, you have two things confirming that, that might be a good place to place a sell-trade. You have the divergence plus the chart pattern there; the double top. And you do have a nice sell-off that results after that.
As you probably noticed in this lesson, the stochastic oscillator is very similar to the RSI, and they’re both momentum oscillators. So, many traders will use one or the other. They’ll try out both, and figure out which one works better for them, for identifying the momentum in whatever instrument they’re trading. Another way that’s it’s used is with, in conjunction with the RSI, to confirm each other; so to confirm opinions on momentum.
A lesson on how to trade the stochastic oscillator for active day traders and investors.
In our last lesson we learned about the RSI indicator and some of the different ways traders of the stock, futures, and forex markets use this in their trading.
In today’s lesson we are going to look at another momentum oscillator which is similar to the RSI and is called the Stochastic. Let me start by saying that there are 3 different types of stochastic oscillators: the fast, slow, and full stochastic. All of them operate in a similar manner however when most traders refer to trading using the stochastic indicator they are referring to the slow stochastic which is going to be the focus of this lesson.
The basic premise of the stochastic is that prices tend to close in the upper end of their trading range when the financial instrument you are analyzing is in an uptrend and in the lower end of their trading range when the financial instrument that you are analyzing is in a downtrend. When prices close in the upper end of their range in an uptrend this is a sign that the momentum of the trend is strong and vice versa for a downtrend.
The Stochastic Oscillator contains two lines which are plotted below the price chart and are known as the %K and %D lines. Like the RSI, the Stochastic is a banded oscillator so the %K and %D lines fluctuate between zero and 100.
