Technical Tools For The Day Trader:
Techniques for Capturing Intraday Profits.
Technical analysis can
be defined as the study of past price behavior in an effort to determine
patterns and trends that are believed to be predictable of the future. At the
core of this school of thought is the assumption that human behavior is
repetitive in nature. We all recognize that, although human behavior patterns
may have recurrent tendencies, they do not normally express themselves in the
same exact, mechanical manner each time. Even with this qualification in mind,
technical analysis is capable of providing us with the ability to make price
forecasts characterized with an improved probability of outcome. It can help us
achieve the "edge" required in our pursuit of long-term consistent success.
A wide array of technical approaches is available. Some are better suited to
particular personalities and styles of trading than others. This article will
focus on just a few that I have found to be consistently helpful in interpreting
intraday market behavior and making short-term price forecasts.
My trading timeframe of choice is the intraday, primarily because it affords the
greatest degree of immediate feedback. An important element for consistent
success is the ability to quickly realize one's mistakes. Intraday trading
offers us a way to "have our finger on the button", and ready to take quick
evasive action should our market judgements prove incorrect. Technical analysis
tells us what has happened on a fairly consistent basis in the past, but it
makes absolutely no guarantees about the future.
Oscillator
Divergence/Momentum Confirmation
The nature of day trading requires that the futures trader make a constant
assessment as to whether a market is in a trending or trading-range mode. If the
mode is determined to be trading-range we need a convenient means of identifying
short term reversal points. On the other hand, if the mode is assumed to be
trending, we require a means of identifying (1) an appropriate entry point based
on the trend currently in force, and (2) an appropriate exit point based on
likely trend exhaustion.
An effective means of identifying such short term intraday market turning points
involves an evaluation of the momentum behind successive market swings. Price
momentum is the measure of the rate, or speed, of price change. Normally, if we
are to expect successive market swings to continue creating new highs or new
lows, we would expect the rate of price change to increase along with the move
to new highs or new lows. If successive swings do not have an increase in
momentum, the validity of any new push higher or lower is called into question.
One very effective tool for measuring price momentum is the 3/10 Oscillator. It
is a simple indicator constructed by subtracting the 10 period Exponential
Moving Average from the 3 period Exponential Moving. As an alternative, most
charting packages offer construction of the MACD indicator (Moving Average
Convergence-Divergence). The 3/10 Oscillator can be simulated with the MACD by
setting the short term parameter to 3, the long term parameter to 10, and the
smoothing parameter to 1.
When using the 3/10 Oscillator, we are attempting to identify one of two
conditions on successive market swings that move to either new highs or to new
lows. The first of these conditions is referred to as "Oscillator Divergence"
and the second as "Momentum Confirmation". The two terms describe opposite
conditions. Typically, each successively greater swing pivot high or swing pivot
low will be accompanied by one or the other.
In a market trending towards lower prices, Oscillator Divergence is described as
a swing to new lows in price which is accompanied by a higher low in the
oscillator. In a market moving towards higher prices, it is described as a swing
to new highs in price which is accompanied by a lower high in the oscillator.
Examples of both conditions are presented in the charts below.
In essence, Oscillator Divergence indicates that the current market movement is
losing momentum. It is at these times that a reversal is most likely. If we had
been considering a trade in the direction of the expected reversal, this would
be an opportune time to initiate entry. On the other hand, when Momentum
Confirmation occurs, we know that the current swing direction has some "oomph"
left to it, and it would be best to either stay with existing positions or look
for an opportunity to climb on board.
When properly used, the 3/10 Oscillator can become a very helpful tool for the
day trader. It is a quick and effective means of measuring market momentum,
revealing valuable information about the market's underlying intent. Become
proficient in its use, but also realize that it is not infallible.
Pivot System
Support and Resistance
Judgements made about likely market behavior which are based on momentum
analysis can be even more productive if we have predetermined levels available
which can act as "price templates" in interpreting the day's trading activity.
The "Pivot System" is one such approach.
Floor traders and other professionals who do the actual buying and selling of
futures contracts in the trading pits of the exchanges, generally employ very
similar systems for valuing the price of these instruments in the absence of
significant outside influences. This Pivot System of Support and Resistance
determines relative valuation levels based on price activity of the prior day.
Pivot System price levels act as potential support and resistance zones
throughout the day. They serve as focal points for floor professionals as they
adjust their bids and offers, especially when trading activity is slow. The
off-floor day trader is able to use these same values as an aid in determining
appropriate areas for trade entry, stop placement, and exits.
The formulas for calculating Pivot System Support and Resistance Levels are as
follows:
DP = (H + L + C) / 3
R1 = 2 * DP - L
S1 = 2 * DP - H
R2 = DP + (R1 - S1)
S2 = DP - (R1 - S1)
DP represents the Daily Pivot. R1 and R2 identify the resistance levels above
the Daily Pivot. S1 and S2 identify the support levels beneath the Daily Pivot.
The principle level of reference is the Daily Pivot. Generally, as we enter each
trading day, we regard this level as our balance point between bullish and
bearish forces. A demonstration of significant price activity above the Daily
Pivot is considered to have bullish implications, while activity below is
bearish. Although actual trade entry and exits are initiated by a variety of
other market factors, we first look at price behavior relative to the Daily
Pivot level as an aid in determining the market's general directional bias.
The day's trading
activity can generally be thought of as revolving around and gravitating towards
the Daily Pivot level. As price moves away from this zone and approaches either
the first level of resistance (R1) or the first level of support (S1), market
behavior becomes increasingly important. Any rejection of these newly attained
levels increases the likelihood of a return to the Daily Pivot. On the other
hand, a breach of either of these initial levels is regarded as market
acceptance and a perceived change in the valuation of the instrument being
traded.
Additionally, should the market extend its move even further from the Daily
Pivot, penetration through each successive level of support or resistance is
generally regarded as having drawn in a greater degree of participation from
off-floor interests. An increase in off-floor interests represents a greater
likelihood that longer-term positions are being established, resulting in
greater potential for the market to trend even further. Each consecutively
greater level of Pivot System support or resistance breached is generally
regarded as having stirred the interest of successively longer term
participants.
Once the market
has made a convincing breach of a particular support or resistance level, that
level is considered to have reversed its support/resistance role, and,
subsequently, becomes a test point for further market activity. For example, in
the chart to the right, when price action develops into an upside break of the
first level of resistance (R1), the retracement move back towards that level is
considered a test of its integrity. A successful test occurs when the
retracement move is turned away and price moves even further to the upside -
which adds even greater credibility to that level as a renewed valuation point.
Additionally, any further move away from that level has the potential to force
the market through successive levels of support or resistance, drawing players
of even longer time-frame perspectives into the market . . . and so on,
continually expanding the market's range of activity.
When properly used, Pivot System Support and Resistance Levels can become a very
helpful tool for the day trader. The approach is not only a quick way of gauging
intraday valuation levels, but also offers an effective means of applying
interpretative "templates" to market activity so as to better understand market
behavior and spot opportunity. They help to determine when and where short-term
intraday trends are likely to hesitate, and can also serve as "test points" in
deciding whether the market may be more likely to either continue or reverse its
current direction.
Dynamic Support
& Resistance Levels for Intraday Trading
As helpful as Pivot System levels often are, a significant drawback to their use
lies in the fact that they are calculated from the prior day's price action, and
may not accurately reflect recent changes in market psychology. Effective
intraday trading also requires a means of identifying support and resistance
which can more easily adapt and more accurately represent price activity under
rapidly changing market conditions. The 20 period Exponential Moving Average
(20EMA) can be used to create these more "dynamic" levels of support and
resistance. Unlike Pivot System S&R levels that remain constant throughout the
day, the 20EMA changes in accordance with more immediate changes in price. This
feature makes them a very effective tool, especially when significant shifts in
market psychology occur between Pivot System levels, and after large thrusting
impulse moves.
My principle intraday chart reference is the five minute timeframe with frequent
note of other periods as market conditions warrant. For this reason, the 5 min.
20EMA is our most often referenced moving average. However, it is also helpful
to additionally graph both the 15 min. and 30 min. 20EMAs on the same 5 minute
chart. This is accomplished by plotting the following values.
5 min. 20EMA - plot a 20 period Exponential Moving Average.
15 min. 20EMA - plot a 60 period Exponential Moving Average (15/5*20)
30 min. 20EMA - plot a 120 period Exponential Moving Average (30/5*20)
It is important to recognize that the 15 and 30 minute values arrived at with
this method are not exact and precise representation of the corresponding 15 and
30 minute 20EMAs, but for purposes of identifying potential support and
resistance levels, you will find the technique quite useful.
The 20 period EMA is treated as we would any other potential support or
resistance level. In congested, trading range market conditions, these levels
can be violated rather easily. However, when price begins to trend, the 20EMA
can be a valuable aid in determining appropriate areas in which to take action
either by establishing new positions . . . or baling out of existing ones.
One of the more frequent uses of this indicator comes into play when we began a
particular trading day expecting the trend established in the previous day to
continue. A common strategy on such days is to look for an opportunity to enter
on the first retracement move which takes price back towards a likely support
(if in an uptrend) or resistance (if in a downtrend). The first level of support
or resistance encountered is likely to be that of either the 5 minute 20EMA, the
15 minute 20EMA, or the 30 minute 20EMA (chart above right). It is important to
keep an eye on these levels when we are expecting trend continuation. Once a
trend has been established, it is very often the case that one of these levels
(most often the 5 min. 20EMA) will contain the price action quite effectively.
The 20 period EMA
can also come into play immediately following large news-driven price thrusts
(chart at right). Trading conditions can often be so volatile during such
periods that I generally discourage any sort of participation until the initial
hysteria subsides. Typically, the strong impulse thrust that accompanies such
events are the beginning statement in a new trend move. Such price behavior will
usually undergo some sort of retracement activity before an advance of
significance takes hold. Again, the 20 period EMA is an excellent tool for
gauging the degree of retracement and likely return to the trend.
As stated earlier, the "dynamic" characteristics of the 20 period EMA is what
makes the indicator such an important tool. It's ability to react in accordance
to more immediate changes in the market environment make it a valuable aid in
creating structure out of essentially unstructured events.
Use of Prior Day
Highs and Lows
Each of the intraday trading techniques discussed so far have relied on
reference levels arrived at by means of mathematical calculations. The technique
discussed in this section, in contrast, will deal with a set of support and
resistance levels which are much more intuitively obvious. In short, we will
discuss a technique for using the prior day's price extremes as a means of
determining market-based valuation levels.
If market activity is thought of as an auction process, where bidders and
sellers are constantly vying for the most advantageous price, daily timeframe
highs and lows represent the outer extremes of accepted value for any particular
trading day. The highest price achieved during the day represents the maximum
that buyers were willing to offer for the commodity, and the lowest price
represents the minimum that sellers were willing to accept. For this reason,
subsequent price action has a tendency to remain within the boundaries of
apparent value as defined during the previous day of trading.
Under typical
market conditions (news-driven price thrusts being one notable exception) a
successful breach of a prior day high or low is normally preceded by several
failed attempts. Once achieved, such price action often represents an important
shift in market psychology with the potential to create a new trend move.
One approach for taking advantage of this market scenario is to use the actual
break of the prior day high or the prior day low as the trigger into the trade -
going long on a break of the high, and short on the break of the low. Using such
a method for market entry is certainly viable, and, in fast market conditions
may be the ONLY way of participating. However, it is considered to be a rather
aggressive technique, for forays into new areas of market valuation are
sometimes rejected in very quick fashion. A more conservative and risk averse
approach is to delay entry until some sort of price retracement can occur. Such
short-term pullbacks often take place before a new trend move can begin in
earnest. Many times, a breach of the prior day high or low will retrace all the
way back to the original breakout point. If not, the next most likely level of
retracement will be that of the 5 min. 20EMA.
Price analysis relative to prior day highs and lows can also prove helpful when
markets get caught in extended, tight-range trading conditions. This kind of
market scenario is often followed by extreme range expansion and a pickup in
volatility. Sometimes the increase in volatility can be very sudden and
dramatic, leading to trading days well-suited for capturing large profits - but
only if you've chosen the correct breakout direction.
Whenever low volatility conditions have been identified, a break of a prior day
high or low can often serve as the cue that the expected range expansion move
has begun and can put us on watch for reduced-risk ways to participate. But even
before such a break occurs, there are a few techniques that offer an advanced
assessment of likely breakout direction and allow for earlier entry. For
example, we can often determine directional clues from price action relative to
the prior day high, prior day low, and the current Daily Pivot. If the market
first approaches the prior day low, and is then repelled upwards through the
Daily Pivot, breakout direction is likely to be towards higher prices (below
left chart). Similarly, if the prior day high is approached, repelled, and price
then moves through the Daily Pivot from above, likely breakout direction is to
the downside (below right chart). Furthermore, often directional clues can also
be found in market behavior near the Daily Pivot. If price activity is unable to
breach this level, the expected breakout will often develop on a path opposite
that of the original approach.
Prior day highs and prior day lows represent extreme points of apparent value.
As such, they contain the potential to act as support and resistance levels
throughout the trading day. Price behavior near these levels can offer valuable
clues as to the market's underlying intent.
Conclusion
Typically, most new traders approach the study of technical analysis with an eye
towards identifying a single indicator, system, or trading methodology which,
when practiced with precision and discipline, will reap rewards on each and
every trade attempt (or at least very nearly so). Many traders, especially
beginners, in their unending search for this one and only ultimate trading tool,
tend to look at this discipline as having such potential . . . as containing the
possibility of being the long sought-after magic key which unlocks the hidden
secrets of future market direction. It is important that we not regard ANY
technical trading tool in this light. Instead, they are better regarded merely
as an aid in summarizing and simplifying certain discretionary aspects of our
trading routine. Technical analysis gives an indication of what has happened on
a fairly consistent basis in the past, but it make no guarantees of the future.
The techniques discussed in this article will jumpstart your understanding and
interpretation of price behavior and underlying market intent, but don't expect
them to become your Holy Grail. It is very likely that it may take a great deal
of practice before you can comfortably integrate them into your normal trading
routine. Some will be more effective under certain market conditions than
others. Plan on spending considerable time with each tool before you start to
fully realize its benefits as well as its shortcomings. As with all effective
trading tools and techniques, nuance and idiosyncrasy become more apparent with
practice.
