Overview

The strategy is named “Dual Exponential Moving Average Crossover Algorithmic Trading Strategy”. It calculates dual exponential moving averages (EMA) and generates trading signals when the EMAs cross over. Combined with the algorithmic trading principles for order entry, it automates the entire trading process.

Strategy Logic

The core logic of this strategy is based on the dual EMA crossovers. Indicator 1 is the 20-day EMA and Indicator 2 is the 50-day EMA. A buy signal is generated when the shorter-term EMA crosses over the longer-term EMA from below. A sell signal is generated when the shorter-term EMA crosses below the longer-term EMA from above. So the crossover of EMAs with different parameters is used to determine market entry and exit points.

In addition, the Vortex indicator is used to aid in identifying the trend and generating trading signals. The Vortex indicator determines the bullish or bearish momentum by comparing the difference between the highest price and yesterday’s close, and the lowest price and yesterday’s open, over a 1-day and 3-day period. Using the Vortex can help filter out some less significant signals from the EMA crosses.

When a trading signal is generated, the built-in money management module helps manage risks by controlling position sizing based on predefined profit loss ratios. Stop loss and take profit levels can also be set to lock in profits and limit downsides.

Advantage Analysis

  1. The strategy integrates dual EMA crossovers and the Vortex indicator to take advantage of both, thus improving signal accuracy

  2. The automated trading system removes emotional human errors and minimizes risks

  3. The auto stop loss/take profit functions limit max loss for each trade

  4. The money management module controls capital allocation for each trade, thus manages overall risks

Risk Analysis

  1. EMA crossovers may generate false signals. And the Vortex indicator cannot completely filter out false signals either. There can still be some losing trades.

  2. Black swan events can lead to huge losses on open positions.

  3. The strategy relies on stop losses to control drawdowns. If stopped out, losses may exceed expectations.

Improvement Opportunities:

  1. EMA parameters can be further optimized to improve signal quality

  2. More indicators may be added to better filter signals

  3. Machine learning algorithms may help auto-optimize parameters

Conclusion

Overall this is a typical dual EMA crossover strategy for medium-term trading. It identifies trading opportunities from EMA crossovers. The biggest advantage lies in using indicators like the Vortex to filter signals, executing the automated strategy reliably, plus the embedded stop loss/take profit functions to mitigate risks. Going forward, strategy performance may be further enhanced through parameter tuning and integrating more complementary indicators.
