Overview

This strategy uses average double filtering and multi-level trend direction confirmation mechanisms to design a relatively stable tracking system. It consists of three main parts:

  1. An optimized trend tracking system based on improved double peak oscillators to determine the major trend direction.

  2. A sub-trend filtering system based on a combination of multiple cycle moving averages to further filter out some noise.

  3. The Alpha Index provides final confirmation to ensure reliability of trading signals.

With the triple protection described above, the strategy can judge major trends more accurately and filter short-term market noise very effectively.

Principle

Main Trend Tracking

It uses an improved double peak oscillator TOTT and a Close Series double trend filter to calculate the main trend direction. TOTT itself has very strong filtering capabilities against noise. The Close Series provides an additional level of confirmation. The combination of the two can determine major trends very accurately.

Subtrend Filtering

In addition to the main trend judging system, the strategy also sets up a sub-trend filtering system based on EMA combinations of multiple cycles. According to the Golden Cross and Dead Cross confirmation levels of the EMA lines, the reliability of judgments on the main trend direction is further improved and more noise is filtered out.

Alpha Confirmation

When entering and exiting positions, the strategy also checks the value of the Alpha Index to ensure reliability of final trading signals. Alpha reflects the buying and selling power in the market and is a good confirmation indicator.

Advantages

  • Multi-level protection design for more accurate major trend judgments
  • Powerful noise filtering capability
  • Stable and reliable trading signals
  • Large parameter optimization space

Risks

  • Signal frequency may be low
  • The tracking system uses moving averages, which can be broken in drastic market changes

To mitigate the risks, parameters can be adjusted to optimize tracker sensitivity, or more reversal indicators can be added as final filters.

Optimization Directions

  • Adjust double peak oscillator parameters to find better parameter combinations
  • Try parameter optimization of different moving average types
  • Optimize moving average cycles in EMA combination
  • Enhance Alpha filtering mechanism
  • Add stop loss mechanism

Conclusion

The overall design of this strategy is robust, with proper measures and multiple protections. The powerful noise filtering gives it stable performance. There is room for further improvement through continuous parameter optimization and mechanism enhancements.

//
// Revision:        5
// Original Author: @JayRogers
// Revision Author: JustUncleL revisions 3, 4, 5
//
// *** USE AT YOUR OWN RISK ***
//  - There are drawing/painting issues in pinescript when working across resolutions/timeframes that I simply
//    cannot fix here.. I will not be putting any further effort into developing this until such a time when
//    workarounds become available. 
//    NOTE: Re-painting has been observed infrequently with default settings and seems OK up to Alternate 
//          multiplier of 5.
//          Non-repainting mode is available by setting "Delay Open/Close MA" to 1 or more, but the reported
//          performance will drop dramatically.
//
// R5.1 Changes by JustUncleL
//  - Upgraded to Version 3 Pinescript.
//  - Added option to select Trade type (Long, Short, Both or None)
//  - Added bar colouring work around patch.
//  - Small code changes to improve efficiency.
//  - NOTE: To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
//  9-Aug-2017
//  - Correction on SuperSmooth MA calculation.
//
// R5 Changes by JustUncleL
//  - Corrected cross over calculations, sometimes gave false signals.
//  - Corrected Alternate Time calculation to allow for Daily,Weekly and Monthly charts.
//  - Open Public release.
// R4 Changes By JustUncleL
//  - Change the way the Alternate resolution in selected, use a Multiplier of the base Time Frame instead,
//    this makes it easy to switch between base time frames.
//  - Added TMA and SSMA moving average options. But DEMA is still giving the best results.
//  - Using "calc_on_every_tick=false" ensures results between backtesting and real time are similar.
//  - Added Option to Disable the coloring of the bars.
//  - Updated default settings.
//
// R3 Changes by JustUncleL:
//  - Returned a simplified version of the open/close channel, it shows strength of current trend.
//  - Added Target Profit Option.
//  - Added option to reduce the number of historical bars, overcomes the too many trades limit error.
//  - Simplified the strategy code.
//  - Removed Trailing Stop option, not required and in my opion does not work well in Trading View,
//    it also gives false and unrealistic performance results in backtesting.
//
// R2 Changes:
//  - Simplified and cleaned up plotting, now just shows a Moving Average derived from the average of open/close.
//  - Tried very hard to alleviate painting issues caused by referencing alternate resolution..
//
// Description:
//  - Strategy based around Open-Close Crossovers.
// Setup:
//  - I have generally found that setting the strategy resolution to 3-4x that of the chart you are viewing
//    tends to yield the best results, regardless of which MA option you may choose (if any) BUT can cause
//    a lot of false positives - be aware of this
//  - Don't aim for perfection. Just aim to get a reasonably snug fit with the O-C band, with good runs of
//    green and red.
//  - Option to either use basic open and close series data, or pick your poison with a wide array of MA types.
//  - Optional trailing stop for damage mitigation if desired (can be toggled on/off)
//  - Positions get taken automagically following a crossover - which is why it's better to set the resolution
//    of the script greater than that of your chart, so that the trades get taken sooner rather than later.
//  - If you make use of the stops, be sure to take your time tweaking the values. Cutting it too fine
//    will cost you profits but keep you safer, while letting them loose could lead to more drawdown than you
//    can handle.
//  - To enable non-Repainting mode set "Delay Open/Close MA" to 1 or more.
