The EA was optimized at a historical distance of five years, so you can see periods of quite long stagnation on the chart. This is normal for long term trading. During the development of the expert Advisor, the main attention was paid to the reliability and stability of the long-term trading. You can try to optimize the EA at a short distance to adapt to the current market, but my recommendations are to follow the proven settings.
The EA does not use risky strategies such as martingale and others.
Your computer must be turned on around the clock, so I recommend using VPS.
