Upper channel line = EMA + EMA · Channel coefficient
Lower channel line = EMA - EMA · Channel coefficient
A channel drawn in an uptrend tends to fit the peaks. Rallies in a bull market
are much stronger than declines, and bottoms seldom reach the lower channel
line. In a downtrend, a channel tends to track bottoms, while the tops are too
limp to rise to the upper channel line. It is unnecessary to draw two separate
channels, one for the tops and the other for the bottoms; just follow the
dominant crowd. In a flat market expect both tops and bottoms to touch their
channel lines.
When we are bullish, we want to buy value near the rising EMA and take
profits when the market becomes overvalued - at or above the upper channel
line. When bearish, we want to go short near the falling EMA and cover when
the market becomes undervalued - at or below the lower channel line.
When the EMA rises, it identifies an uptrend. It is a good idea to buy near that
EMA or slightly higher or lower, depending on the stock’s recent behavior.
At point A, EMA stands at 35, while the low point of the bar reaches 33 - a 2-
point downside penetration. At point C, the price low penetrates the EMA by
1 point, at D by 2.25, at F by 4, at point H by 0.75, and at J by 4. Those shortterm
bottoms keep alternating between shallow and deep - an important piece
of intelligence when you try to decide where to place your buy order. If the
latest penetration was shallow, expect the next one to be deep, and vice versa,
and place your buy orders accordingly.
The place to sell stocks purchased near the EMA is at the upper channel line.
Looking back, it is easy to see that buy-and-hold would have worked even
better in TARO, but the future is not nearly as clear at the right edge of the
chart. Buying value near the EMA and taking profits above value, near the
upper channel line, is safer and more reliable. Stock bought at A can be sold
at B, bought again at C or D and sold at E, and so on.
A trader can grade his performance, based on the percentage of the channel
he takes in profits on any given trade. For example, at the right edge of the
chart, the upper channel line stands at 97 and the lower at 69, making the
channel 28 points high. An A trader should get the minimum of 30% or 8.4
points out of the next trade, a B trader 20% or 5.6 points, and a C trader 10%
or 2.8 points.
At the right edge of the chart, prices are hitting the upper channel line. It is
time to take profits on stocks purchased in area J, near the EMA, and wait for a
pullback.
If you buy near a rising moving average, take profits in the vicinity of the
upper channel line. If you sell short near a falling moving average, cover in the
vicinity of the lower channel line. Channels catch swings above and below
value but not major trends. Those swings can be very rewarding. If you can
catch a move from the EMA to the channel line in bond futures, you’ll make
about $2,000 in profit on a $2,000 margin. If you can do this a few times a year,
you’ll find yourself far ahead of many professionals. |
