1. Duality of Trend versus Volatility in Scale Space
We only study global liquid financial marketsincluding currencies, equity indexes, commodity futures, etcWe recognize that market prices are stochastic and dynamicWe are looking for more sensible models beyond random walk
Volatility is a central notion in academic finance – option pricing, portfolio theory, risk metrics, etcTrend is a central notion in professional finance – technical analysis, trend following, momentum trading, strength investing, etc
Volatility is defined by the variance of the price around the trend axis.Trend is defined by the bias in the volatility of the price
Neither can be well-defined without the otherTrend and Volatility form a unity of signal-noise duality
Pan Heping [email protected] 2010-12-8 8
Trend and Volatility cannot be defined without each other
Definition of Trend in Technical Trading:
Up-Trend: Price exhibits Higher Highs and Higher LowsDown-Trend: Price exhibits Lower Lows and Lower Highs

Volatility is defined by variance of price returns around average (MA) of price returns
Pan Heping [email protected] 2010-12-8 13
A Dynamic Structure for Modeling Price Process
Definition of Trend and Volatility depends on the Time ScaleSo what could be an objective Reference System for expressing the stochastic-dynamic characteristics of the market prices ?We reckon there is no absolute Reference System, and it must be relativistic to the recent history of the market prices and economic information flows. If this Reference System is relativistic to the recent price history, it should correspond to a Dynamic Structure of price time series.Such a Dynamic Structure should be expressive enough for modeling typical tendencies (market regimes) of price process – Trend, Swing and Breakout.
We found that Yin-Yang Volatility Surface Evolution (YYVSE)provides such a Dynamic Structure.

Philosophical and Psychological Underpinnings of YYV
Chinese Yin-Yang Philosophy (Book of Change, 2800BC-2737BCcan be summarized in 4 principles:
1. Everything has both yin and yang aspects, although yin or yang elements may manifest more strongly in different objects or at different times or situations.
2. Yin and yang arise together from an initial quiescence or emptiness, and continue moving in tandem until quiescence is reached again
3. Yin and yang transform each other. Whenever one quality – yin or yang – reaches its peak it will naturally begin to transform into the opposite quality.
4. Yin and yang constantly interact, never existing in absolute stasis. The interaction of the two gives birth to new things.
Pan Heping [email protected] 2010-12-8 30
Philosophical and Psychological Underpinnings of YYV
Western Dialectics Philosophy (Socrates (469 BC – ) and Plato, Hegel and Marx)can be summarized in 4 principles:
1. Everything is transient and finite, existing in the medium of time.2. Everything is made out of opposing forces or opposing sides
(contradictions)3. Gradual changes lead to turning points, where one force overcomes
the other (quantitative change leads to qualitative change)4. Change moves in spirals or helices, not circles (referred to as
“negation of the negation”).

Entry Conditions
If the market has been ‘bottomed’ and then is ‘bottomup’ with a high probability Prob(‘bottomup’| ‘bottomed’, prices, MA, PanRiver, PanLowerBand)
Then go long with a market order with a stoploss level and a takeprofit level
If the market has been ‘topped’ and then is ‘topdown’ with a high probability Prob(‘topdown’| ‘topped’, prices, MA, PanRiver, PanHigherBand)
Then go short with a market order with a stoploss level and a takeprofit level

Exit Conditions and Position Management
Exit Conditions:If the position is long and
( the price crosses down its stoploss level or the price crosses up its takeprofit level or the market is ‘topdown’)
Then exit the long position.
If the position is short and( the price its stoploss level or the price its takeprofit level
or the market is ‘bottomup’)Then exit the short position.
Position Management:Bet a constant ratio of the current capital for position sizing,
and use trailing stop loss orders to manage the floating profits.

The Standard US Dollar Index
Standard Definition: Started in 1973 with a base of 100, the US Dollar Index (USDX) is a real-time measure of the value of the United States dollar relatives to a basket of foreign currencies – a majority of its most significant trading partners. Mathematically, it is calculated as a weighted geometric mean of the dollar’s value compared only with
EUR (57.6%), JPY (13.6%), GBP(11.9%), CAD (9.1%), SEK(4.2%), CHF(3.6%).

12. Conclusions1. Trend and Volatility form a unity of Signal-Noise duality.2. Yin-Yang Volatility form a unity of Yin-Yang duality,
which expresses the duality of trend and volatility in computable form on any given scale of time.
3. Yin-Yang Volatility Surface (YYVS) expresses the YYV throughout the scale space of price-time.
4. The YYVS Evolution (YYVSE) provides a Dynamic Structure for Modeling the Behavioral Patterns of the price dynamics.
5. Even simple explorations of YYVSE give rise to useful trading strategies in forex market.
