Nice post! I am happy that you learned about Trend Following and what a good trading strategy looks like.
The equity chart is not as nice on the short term, but at least you will keep your funds safe.
If you like the style, I would suggest you to read Trend Following by Michael Covel.. Great book that describe the mentality and basic fundamentals of it.
Martingale and mean reversion strategies are very dangerous. They can work, but they need to be very well managed and still have risk management in place, which I didnt see yet on Zignaly from these kind of trader.
Risk management should be a core component of any strategy, and not left to the discretion of the service provider and how he feels about the market.
