An Example of a Trading
System based on the SBV Oscillator
November 21, 2008
+20% on the S&P 500 in two months
This week's
SBV chart example is a continuation of the example of
September 26, 2008.
In this week's example, we use the same settings that were previously used
by showing the consistency of our trading system over the long period of
time.
This week's SBV chart example is based on the 60-day SBV(20) S&P 500 chart.
Chart 1. Relationship between the SBV oscillator and
index reversal points. S&P 500 index. 60-day view. 1 bar = 1 hour. SBV(20)
Signal Level 1: If the SBV runs above plus 20% or falls below
minus 20% and reverses its trend without reaching 33%, use 20% as the signal
line.
Signal Level 2: If the SBV runs above plus 33% or falls below
minus 33%, use 33% as the signal line.
Once the SBV indicator has
declined below a negative signal level (the indicator will now show red), we
enter a short position (if we are not already short);
Once the SBV indicator
advances above a negative signal level (after having been below that level),
we will enter a long position (the indicator still shows
red);
Once the SBV indicator
rallies above a positive signal level (the indicator will now show green),
we enter a long position (if we are not already long);
Once the SBV indicator
declines below a positive signal level (after having been above that level),
we will enter a short position (the indicator still shows
green);
Additional Stop Loss
Rule - If the SBV had fallen into negative territory and has begun
to rise without, but has not yet reached the signal line, close the short
position when the SBV is back in positive territory, and stay in cash until
a new buy signal appears. Do the opposite for a long position.

(additional stop-loss rule) system.
In our Market outlook on September 17, 2008 we wrote:
"We will repeat for those who use a 60-day
SBV(20) simple trading system what we mentioned on January 23rd of 2008: we
recommend that you lower the negative level from minus 20% to minus 60-70% after
such a strong Selling volume accumulation - there is no need to wait until the
SBV runs to the minus 30-20% level for confirmation of the recovery."
This is one way to improve the system. When the market has moved in one
direction for a prolonged period of time and the accumulation of Selling or
Buying volume grows very significantly, it is reasonable to expect a sharper and
a stronger reversal than usual. In this case it could be too late to close a
position when the SBV has crossed the 20% level. This helped to spot the exact
bottom of the crash in January and March of 2008, as it did on September 19,
2008.
Explanation of November 21, 2008 signal
In our Market Outlook on November 20, 2008 we stated:
“There has been a large area where bearish volume accumulation (red SBV) has
been very intense. This area extends from November 6, 2008 until now and points
to the possibility of a strong recovery. Something that we have mentioned
before, in the case of large volume accumulation to the index and downside
supported by big volume surges, it could be enough to have 10-20% SBV rise to
confirm the higher odds of a recovery. Since a recovery movement could be sharp
and strong, waiting until the SBV rises to minus 30 or minus 20% may prove to be
too late.”
The same principle that was applied on September 18, 2008 (see above) could
be applied on November 21, 2001 when the SBD began to move upward.
Note: The 20%
level for the SBV indicator was determined in relation to the prevailing market
conditions at the time that the trading examples were selected. In
order to establish the optimal critical levels for the SBV indicator, traders
should consider the current market situation and review the history of prior
volume surges, including their magnitude (i.e., the level that the SBV indicator
reached).
Our charts are unique in that they give traders the opportunity to
choose the specific chart settings that best fit their personal trading styles
and risk tolerances. Traders can thus develop and test their own trading
systems. On our charts, you can scroll back in history to test any system that
you have created.
