Editor's Note:
Kevin Haggerty is the former head of equity trading at Fidelity Capital.
This article was originally published on TradingMarkets.com January
2001. The stock prices may have changed, but the information is timeless.
Trading is searching for high-probability opportunities, as, regardless
of your holding period, you are always striving to gain an edge.
I have found that convergence of indicators such as support, resistance,
trend lines, moving averages, Fibonacci levels and volatility bands
also give you an edge and chance for a high-probability entry. You
can be very successful by buying pullbacks in uptrends (the reverse
is true for sellers) when they coincide with convergence.
This lesson will demonstrate the interaction of convergences from
an intermediate period on the daily chart with the one-day volatility
bands. (To better understand the lesson, you should first read my
article, "Short-Term Volatility Trading Bands," in the
Trading Strategy section on the site.)
As I have mentioned in my previous commentary, in order to maximize
use of this strategy, you should always have your key stocks or
indexes framed in advance so that you may take advantage of any
air pockets that occur which might give you good entry.
On the Jan. 20 daily chart of General Electric [GE|GE], I have
framed the key reference points, so follow along on the chart as
I address them.

- X1 is a significant bottom in October 1999 at 114.625.
X2 is a significant top on Dec. 27, 1999, at 159.50.
X1A is a minor bottom at 130.
- After you have marked the significant top and bottom, you can
calculate the Fibonacci retracement levels between 114.625 and
159.50.
The levels are as follows:
.38 142.44
.50 137.06
.618 131.76
.786 124.22
- Draw your key trend lines. See TL 1 and TL 2.
- Identify the key EMAs on the daily chart. Most software packages
have the ability to interface the EMAs of your choice and also
enable you to get your Fibonacci retracement levels. The key exponential
moving averages (EMAs) are as follows:
50-day EMA 144.48
200-day EMA 124.85
The EMAs and the Fibonacci RT levels are located bottom right
on the chart.
- Identify support or resistance levels. In this example, I have
marked the following support levels that come into play:
S3 142.56
S2 130.00
If S1 was penetrated, we would be looking to short so it doesn't
come into play for this example except as the initial point to draw
the intermediate TL 1.
Please note that the S3 level pf 142.56 was made just above the
50-day EMA which was 141.84 on Jan. 5, the day S3 level was confirmed.
As you can see on the chart, the 50-day EMA also acted as support
at the S1 and S2 levels. You should also observe that these pullbacks
all consisted of 3, 5, 8 or 7 day retracements after swing-point
highs. (See footnote on counting pullback days.)1
The S3 support level was made at Trend Line 1. The next convergence
of S3 was that it occurred just above the .618 RT of 141.27, measured
from the XIA bottom of 130 and X2 top at 159.50. (This is not marked
on the chart.)
I threw the curve at you to make the point that these convergences
are important to recognize at both significant and minor bottoms.
Some of your major home runs will come when the .38 level of the
major leg coincides with the .618 level of the minor leg in addition
to the other convergences. If you get a good entry from convergence
and it coincides with a VIX signal for the market, it makes your
trade even stronger.
Remember, these reference points are just alerts, not absolutes.
You must then watch for a reversal entry pattern that puts you in
the trade. This might be a doji or hammer if you are into candles
or a close above the high of the low day, a three-bar reversal,
a 1, 2, 3, 4 or even a 180. (See The TRADEHARD.COM Guide to Conquering
the Trading Markets, 1999, M. Gordon Publishing Group, Los Angeles,
California.)
Regardless of which reversal pattern you use, it is about getting
in the trade when you see it changing direction, not picking a bottom
or top because it fits a number which are just alerts. You should
be looking for buying pressure to take the upper hand as price and
range expand on increased volume.
Now that you have framed GE on the daily chart, let's review the
key points you should be focusing on. After we do that we will combine
these convergences with the Jan. 20 intraday chart. On Jan. 20,
GE opened at 149.68, traded down to 142.625, then rallied from this
key level to 147.125 and this was your high probability trade.
A look at the daily chart shows me the following convergences:
- The .38 RT level of X1 to X2 is 142.44. S3 support level is
142.56.
- GE rallied last time from the S3 level of 142.56 which was
right at the 50-day EMA and Trend line 1. The 50-day EMA on Jan.
20 was 144.48. (See daily chart bottom right.)
- The S3 level of 142.56 where the rally started after an 8-day
pullback was just above the .618 level as measured form X1A level
at 130 to the X2 top at 159.50.
- The .618 RT level of 131.76 coincides with the S2 support level
of 130.
- The .786 level of 124.22 coincides with the 200-day EMA of
124.85
The key reference points which we have framed are enough convergence
to have entered the trade on Jan. 20, assuming you had a reversal
pattern entry. We will have more confirmation when you see it combined
with the Volatility bands.
It is also important to observe the X2 top reversal. GE made the
159.50 top on lighter volume and formed a dynamite triangle pattern
as volatility contracted which usually precedes a strong move. This
is an excellent narrow-range pattern. The tighter it gets, the bigger
the move in most cases. GE broke out of the pattern to the downside
in addition to trading below TL 2 and closed below the past 5 days'
lows. This was a sell signal for any traders that were long and
possibly a short entry for experienced traders only. The question
of whether you should short stocks in strong uptrends is another
topic and not part of this lesson.
Next, we will talk to the Jan. 20 intraday chart of GE where the
low on that day of 142.625 converged with the .38 RT level from
X1 to X2 on the daily chart in addition to the other convergences
we mentioned.
GE developed an air pocket on Jan. 20 as they reported record earnings
but there was confusion about a one-time gain and misplaced fears
that the earnings were inflated by the one-time gain. (Dow Jones
News).
The overreaction started immediately as GE traded down to a low
of 142.625. Any short-term longs were stopped out and sold, some
of the trigger happy institutions let some go because they are all
overweighted in GE big time. The married puts helped accelerate
the slide as the specialist was obviously going to let the stock
fall to a level that attracted buyers which it eventually did.
Hopefully you will soon become one of the few traders that take
advantage of these convergent opportunities.
In order to follow along on this intraday five-minute chart of
GE, you should have a copy of "Short-Term Volatility Bands"
in your hands. The calculations are explained in that strategy.

This example of convergence is to take a high probability day trade
because on the chart I have labeled the price bands from 1 to 2
standard deviations based on one trading day. The calculation to
get the one day constant is 
You divide 1 by 365, then take the square root of the result and
you get 0.0523421. Any calculator with a square root function will
do.
I have also marked the % probability that price will be contained
within the volatility band and probably revert to the mean. Translated,
it means we are looking for trade entries at the bands.
In this example, the 2.0 standard deviation band is 143.22 and
there is a 95% probability that price will be contained by this
band. This assumes no unusual news such as fraud or accounting irregularities.
Just so there is no confusion, I will do the calculation that gives
us the 143.22 volatility band.
- GE closed at 148.72 on Jan. 19, 2000.
- Take the IV (Implied Volatility) of the ATM (at the money)
call and ATM put, add them together and divide by 2.
In this example, we used the most recent month options, which
is February expiration. I used the 150 strike price because GE
was closer to 150 based on its close of 148.72.
The result of this calculation gives you the combined IV of .354.
- The constant is 0.0523421 and the combined IV is .354.
Example:
- 2.0 (standard deviation x .354 (combined IV) = 0.708
- 0.708 x 148.72 (GE) = 105.29
- 0.0523421 x 105.29 = 5.541 points
- 148.72 - 5.51 = 143.21 (2.0 SD, 95% band)
Note: You just add 5.51 to 148.72 for the upper 2.0 SD band.
You do the same calculation for each different volatility band,
starting with the 1.0 SD.
GE dropped like a knife without a rally and gave a buy reversal
entry at B1 with a stop below the low of that first bar below 143.
When it moved above 144, you moved your stop up to break even, which
was 143.50, the entry price.
The stock then dropped to 142.625, which was just above the .38
RT level on your daily chart and just above the S3 support level
of 142.56. GE gave an excellent reversal-entry pattern at this level
and the market dynamics were also better. You got a wide-range bar
(WRB) expansion, which was an outside bar that closed in the top
of its range, above its open, above the previous bar's high and
above the previous two bar closes, and also closed above the previous
low of the first entry pattern.
Once you entered at B2, there wasn't a reversal sell pattern until
you got to the 147.125 level and reversed the lows of the previous
3 bars. Net net, you got back in at 143 1/2-5/8 and you had a defined
exit at 146.75 assuming you took the reversal exit pattern.
Combining time frames and convergences will definitely improve
your trading or investing as you can do the same framework with
mutual funds, with the exception of intraday bands. As you read
this, you might think it is time-consuming to frame, but it really
isn't. Get some software that gives you Fibonacci retracement levels
on your daily chart and frame your key trading stocks or whatever
stock shows up on your stock selection list. If you are just trading
intraday, you can frame the stock during the day and look for entry
points.
It is much stronger when you combine it with the intermediate trend.
When you calculate the volatility bands, start with 2.0, then 1.5,
1.28 and then 1.0. The best trades will usually come from the wider
bands. Please E-mail me on any questions you might have. There is
no such thing as a stupid question.
Good trading.

1 When you count those 3, 5, 8 and 7 bar pullbacks, you arrive
at the number by starting with the most recent bar or the preceding
bar in a situation where you are buying a pullback in an uptrend
(reverse for sellers)). If you have a double bottom, you count that
as one bar. More than that, you will be in a consolidation pullback.
