Overview

This strategy is based on the spectrum moving average, generating trading signals through the golden cross and death cross of the fast and slow moving averages. The spectrum moving average covers a variety of types from simple moving average to oscillating moving average, which can be freely combined through parameter adjustment for strong adaptability.

Strategy Principle

This strategy uses a variant moving average function that can generate 12 different types of moving averages. The basic principle is to calculate two moving average lines, the fast line (Close MA) and the slow line (Open MA). When the fast line crosses above the slow line, a buy signal is generated. When the fast line crosses below the slow line, a sell signal is generated. Stop loss and take profit parameters are also set to achieve automatic stop loss and take profit.

The key logic is to generate two moving average lines through the variant function: closeSeries = variant(basisType, close, basisLen, offsetSigma, offsetALMA) and openSeries = variant(basisType, open, basisLen, offsetSigma, offsetALMA). The variant function encapsulates calculation methods for 12 different types of moving averages. Users can freely select the type through the basisType parameter. This implements the combination of spectrum moving averages.

The basic logic for generating trading signals is: longCond = xlong and shortCond = xshort. That means when the fast line crosses above the slow line, long position is taken, and when the fast line crosses below the slow line, short position is taken.

The entry rule is to go long or go short when the longCond or shortCond condition is met. The exit rule is to close the position for stop loss or take profit when the price movement reaches the preset stop loss/profit points.

Advantage Analysis

The biggest advantage of this strategy is that it can freely combine a variety of different types of moving averages. It is indefinite which types of moving averages are best suited for different markets and timeframes. This strategy provides powerful customizability. Users can determine the optimal parameter combination through repeated testing, thereby formulating the best solution for the specific market.

Another advantage is that the strategy logic is simple and clear, but provides powerful functionality. It is easy for users to understand and use this strategy. At the same time, the abundant input parameters also provide sufficient optimization space for advanced users.

Risk Analysis

The biggest risk with this strategy is that the spectrum moving average itself has a certain degree of lagging. Abnormal price breakthroughs may cause larger losses. In addition, improper parameter selection may also lead to excessive trading frequency or redundant signals.

To reduce the risk, it is recommended to use other indicators to determine the validity of signals and avoid false breakouts. In addition, parameter optimization and backtesting are also essential to find the best parameter combination through repeated testing. In live trading, the position sizing should be appropriately reduced to control single loss.

Optimization Directions

The main optimization directions for this strategy include:

Test more types of moving average combinations to find the best combination
Add filters to avoid false signals, such as combining trading volume indicators, etc.
Optimize the length parameters of the moving averages to find the optimal parameters
Optimize position sizing, stop loss and take profit parameters
Try different products and timeframes

By optimizing in these directions above, the live trading performance of the strategy can be continuously improved.

Summary

This trading strategy implements high flexibility based on the spectrum moving average. It provides powerful customizability for users to freely choose and combine different types of moving averages. The strategy logic is simple and clear, easy to use, and also offers abundant optimization space. Through parameter optimization and risk control, this strategy can adapt to different market environments and obtain steady returns. It is an efficient and flexible trend tracking strategy.
