SIMPLE MOVING AVERAGE

Simple Moving Average (SMA)

A simple moving average is the simplest type of moving average (DUH!). Basically, a simple moving average is calculated by adding up the last “X” period’s closing prices and then dividing that number by X. Confused??? Allow me to clarify.

If you plotted a 5 period simple moving average on a 1 hour chart, you would add up the closing prices for the last 5 hours, and then divide that number by 5. Voila! You have your simple moving average.

If you were to plot a 5 period simple moving average on a 10 minute chart, you would add up the closing prices of the last 50 minutes and then divide that number by 5.

If you were to plot a 5 period simple moving average on a 30 minute chart, you would add up the closing prices of the last 150 minutes and then divide that number by 5.

If you were to plot the 5 period simple moving average on the a 4 hr. chart………………..OK OK, I think you get the picture! Let’s move on.

Most charting packages will do all the calculations for you. The reason we just bored you (yawn!) with how to calculate a simple moving average is because it is important that you understand how the moving averages are calculated. If you understand how each moving average is calculated, you can make your own decision as to which type is better for you.

Just like any indicator out there, moving averages operate with a delay. Because you are taking the averages of the price, you are really only seeing a “forecast” of the future price and not a concrete view of the future. Disclaimer: Moving averages will not turn you into Ms. Cleo the psychic!

Here is an example of how moving averages smooth out the price action.

On the previous chart, you can see 3 different SMAs. As you can see, the longer the SMA period is, the more it lags behind the price. Notice how the 62 SMA is farther away from the current price than the 30 and 5 SMA. This is because with the 62 SMA, you are adding up the closing prices of the last 62 periods and dividing it by 62. The higher the number period you use, the slower it is to react to the price movement.

INDICATORS

Leading vs. Lagging Indicators

We’ve covered a lot of tools that can help you analyze charts and identify trends. In fact, you may now have too much information to use effectively.

In this lesson, we’re going to look at streamlining your use of these chart indicators. We want you to fully understand the strengths and weaknesses of each tool, so you’ll be able to determine which ones work for you and your trading plan… and which ones don’t.
Leading versus Lagging Indicators

Let’s discuss some concepts first. There are two types of indicators: leading and lagging.

A leading indicator gives a buy signal before the new trend or reversal occurs.

A lagging indicator gives a signal after the trend has started and basically informs you “hey buddy, pay attention, the trend has started, you’re missing the boat.”

You’re probably thinking, “Ooooh, I’m going to get rich with leading indicators!” since you would be able to profit from a new trend right at the start. You’re right – you would “catch” the entire trend every single time, IF the leading indicator was correct every single time. But it’s not.

When you use leading indicators, you will experience a lot of fake-outs. Leading indicators are notorious for giving bogus signals which will “mislead” you. Get it? Leading indicators that "mislead" you? Ha-ha. Man we're so funny we even crack ourselves up.

The other option is to use lagging indicators, which aren’t as prone to bogus signals. Lagging indicators only give signals after the price change is clearly forming a trend. The downside is that you’d be a little late in entering a position. Often the biggest gains of a trend occur in the first few bars, so by using a lagging indicator you could potentially miss out on much of the profit. Which sucks.
Oscillators and Trend Following Indicators

For the purpose of this lesson, let’s broadly categorize all of our technical indicators into one of two categories:

1. Oscillators
2. Trend following or momentum indicators

Oscillators are leading indicators.

Momentum indicators are lagging indicators.

While the two can be supportive of each other, they're more likely to conflict with each other. We’re not saying that one or the other should be used exclusively, but you must understand the potential pitfalls of each.
Stochastics

Stochastics are another indicator that helps us determine where a trend might be ending. By definition, a stochastic is an oscillator that measures overbought and oversold conditions in the market. The 2 lines are similar to the MACD lines in the sense that one line is faster than the other.

How to Apply Stochastics

Like I said earlier, stochastics tells us when the market is overbought or oversold. Stochastics are scaled from 0 to 100. When the stochastic lines are above 80 (the red dotted line in the chart above), then it means the market is overbought. When the stochastic lines are below 20 (the blue dotted line), then it means that the market is oversold. As a rule of thumb, we buy when the market is oversold, and we sell when the market is overbought.

Looking at the chart above, you can see that the stochastics has been showing overbought conditions for quite some time. Based upon this information, can you guess where the price might go?

If you said the price would drop, then you are absolutely correct! Because the market was overbought for such a long period of time, a reversal was bound to happen.

That is the basics of stochastics. Many traders use stochastics in different ways, but the main purpose of the indicator is to show us where the market is overbought and oversold. Over time, you will learn to use stochastics to fit your own personal trading style. Okay, let's move on to RSI.
