### The Power Walk-Forward Optimizer (PWFO)

is a cutting-edge automatic walk forward/out-of-sample analysis program that eliminates the ad hoc curve fitted performance and data mining results produced by combinatorial and genetic(grail) optimization of strategy input values on spurious price movements(noise). Included in the in-sample section output for each set of input parameters are 30 new robust and superior performance metrics. The in-sample and out-of-sample periods are user selectable. The PWFO can generate up to 500 different in-sample and out-of-sample date files in one TS run. Statistically speaking, walk forward out-of-sample (oos) analysis must be performed over many(>30) in-sample/oos sections to be statistically valid.

** Available for TradeStation and MultiCharts 64bit**

**The Walk Forward Metric Explorer (WFME)** reads all files generated by the PWFO and searches each PWFO file for performance Metrics that generate statistically best average out-of-sample performance. The Top N Metric filter chooses the PWFO file rows that contain then Top N (N=10 or 50 or etc) values of a PWFO Performance Metric. From the N rows chosen, the WFME chooses the maximum of another PWFO performance metric. This allows two performance metrics in the in-sample section to be used to find the strategy inputs that give the best out-of-sample returns. The Top N criteria ranges are user selectable generating many filter searches in one run. The WFME is a stand alone 64bit exe program that is super fast and automatically displays it's extensive total out-of-sample net profits plus performance results, equity plots and strategy inputs from each filter in Excel. In addition, using modern "Bootstrap" techniques, the WFME calculates the probability of whether or not each filter's out-of-sample results were due to chance.

**The Walk Forward Strategy Inputs with Metric Filtering (WFINP64)** reads all files generated by the PWFO and searches each PWFO file for the best combination of Strategy Inputs and performance metrics Filters that generate the statistically best average out-of-sample performance. A

**Strategy Input/filter** summary is generated and sorted by total out-of-sample net profits after costs for all Strategy Input/metric filters combinations and written to a comma delimited Excel file by the WFINP. The WFINP is a stand alone 64bit exe program that is super fast and automatically displays it's extensive total out-of-sample net profits plus performance results, equity plots and strategy inputs from each filter in Excel. In addition, using modern "Bootstrap" techniques, the WFINP calculates the probability of whether or not each filter's out-of-sample results were due to chance.

### The n^{th} Order *Fading* Memory Polynomial

Using fast advanced mathematical rocket science algorithms, the price series is modeled using an nth order fading memory polynomial of the form: ** price(t) = a**_{0}(t)+a_{1}(t)*t+a_{2}(t)*t^{2}+a_{3}(t)*t^{3}+a_{4}(t)*t^{4}+...+a_{n}(t)*t^{n} The **a**_{n}(t) coefficients are updated *recursively* with each new price bar and then used to give the polynomial's** ***next bar forecast* of price,velocity and acceleration.

### n^{th} Order Fixed Memory Adaptive Polynomial

Using fast advanced mathematical rocket science algorithms that use discrete orthogonal polynomials, the price series is modeled using an n^{th} order polynomial of the form:
** price(t) = a**_{0}+a_{1}*t+a_{2}*t^{2}+a_{3}*t^{3}+a_{4}*t^{4}+...+a_{n}*t^{n}
The **a**_{n} coefficients are recalculated at each new price bar and are then used to give the polynomial's *next bar forecast* of price,velocity and acceleration.

### The Goertzel Algorithm for Cycle Detection (GZ)

Super fast DLL finds the N(user selectable) cycles(frequencies and phases) with the highest amplitudes at each price bar using a lookback of M (user selectable) bars, and creates a 1 bar ahead noise filtered projected combination cycle curve that is followed giving buy and sell signals as the combined cycles curve moves up and down. This process gives a more robust noise filtered signal than a single frequency (dominant cycle) procedure. You are no longer constrained to using only a single frequency. The nCycleGZ algorithm is faster and superior to MESA in finding cycles in noisy price series.

**The Goertzel Strategy is thread safe and can run on multi-core, multi-thread platforms**

** Available for TradeStation, MultiCharts **

### The End Point Fast Fourier Transform System (EPFFT)

Super fast DLL takes the *Fast Fourier Transform* at each price bar, filters the noisy price series using a unique noise filter in the frequency domain, and creates a one bar ahead noise filtered projected price. The EPFFT DLL produces an adaptive broadband (many frequencies) noise filtered signal. This process gives a more robust noise filtered signal than a single frequency (dominant cycle) procedure.

**The EPFFT v3t is thread safe and can run on multi-core, multi-thread platforms**

**The five parameter parabolic** adds a noise filter and changeable starting stop value that minimizes the whipsaw losses that can occur with the regular parabolic indicator. Here this new system is applied to stock and Futures prices to minimize the noise process.

**The Parabolic v2t is thread safe and can run on multi-core, multi-thread platforms**

** Available for TradeStation, MultiCharts**
