If I could only learn one aspect of chart reading it would be knowing how to read support and resistance lines. Support is when a stock price gets buyers to start buying and/or sellers to quit selling. Resistance is just the opposite – where sellers start selling and buyers quit buying. So how do I identify where these price levels actually are so I know which stocks to buy now and the appropriate time to sell them? Well, there are actually a number of fairly reliable methods to find accurate support and resistance lines:
History
The first place I go to find support and resistance lines is by simply looking at the charts. Are there any prices where the stock price kept “bouncing” off of? If it happens multiple times in a relatively short period relative to your chart time frame then you have a support line. This is where the double bottom or double top price formations come from. If a stock can’t break through the resistance it’s going to change directions and try to break support in the other direction.
Price Trend
You’ve likely noticed that for any good stocks to watch, the prices never move in a straight line regardless if they are going up, down, or sideways. If a stock is moving up it first moves up, then comes back down some, and then moves up higher. This is called creating a channel. If you draw a line along the lows of the stock prices and the highs of the stock price in this trend channel you get more support and resistance lines. As long as the price doesn’t break out of the channel it’s likely going to keep heading in the same direction.
Moving Averages
I am probably too big a fan of moving averages. I enjoy fine tuning the number based on different theories or stock to stock to try to see what each given security seems to react to. A moving average is simply an average price over a given period of time. The most commonly used are the 50 day and 200 day moving averages for longer term trading. When a price hits a longer term moving average it tends to stall regardless if it’s moving up or down.
Fibonacci Numbers
The Fibonacci series, the last two numbers in a sequence added together, is found in nature, science, and price cycles. Essentially it goes 1,2,3,5,8,13,21, and so on. When you divide these numbers you get the same percentages and they are found in stock cycles. The price will often retract 38.2%, 50%, or 61.8% If you draw these lines of resistance off a price reversal you can add some clarity with the other methods.
