Lines Of Support And Resistance

Category: Finance, Currency Trading.

The trendline. While the market moves in any direction not along a straight line but along a zigzag, the mutual placement of upper and bottom points of those zigzags permits to plot a line connecting the significant highs( peaks) or the significant lows( troughs) of an appropriate zigzag using technical tools of the computer program.



A trendline is a main initial element for the price chart analysis. To draw a trendline only two points are necessary and the third one is the contact point confirmation. The trendline and a line which is about parallel to it and drawn on the opposite side( through peaks on a bullish trend and through troughs on a bearish) form the trade channel. On a bullish trend chart it should be drawn using troughs, on a bearish- using peaks. Both lines are then channel s borders. The upper and the bottom borders of trade channels are called accordingly support and resistance lines. Lines of support and resistance.


The peaks represent the price levels at which the selling pressure exceeds the buying pressure. The troughs, on the other hand, represent the levels at which the selling pressure succumbs to the buying pressure. They are known as resistance levels. They are called support levels. The reverse is true in a downtrend. In an uptrend, the consecutive support and resistance levels must exceed each other respectively. Although minor exceptions are acceptable, these failures should be considered as warning signals for trend changing.


The longer the prices bounce off the support and resistance levels, the more significant the trend becomes. The significance of trends is a function of time and volume. Trading volume is also very important, especially at the critical support and resistance levels. The importance of support and resistance levels goes beyond their original functions. When the currency bounces off these levels under heavy volume, the significance of the trend increases. If these levels are convincingly penetrated, they tend to turn into just the opposite. Conversely, a strong resistance turns into a firm support after being penetrated.


A firm support level, once it is penetrated on heavy volume, will likely turn into a strong resistance level. In general, to evaluate the reliability( that is the possibility of a break) of the trade channel borders taking a decision to close or to save an existing position one should govern himself with following rules: A channel is the more reliable the longer it exists. A channel is the more reliable the more is his width( "It takes time to break channel" ). Hence, the" solidity" of very old channels( e. g. existing more than 1 year) decreased sharply. The resistance may be broken if it is bounced on the background of a growing volume( "It takes volume to break resistance" ). The support may be broken independent on the volume( "under own weight" ). A steep channel is less reliable in compare to a gentle one.
