Nice question, by the way.
I presume dynamic leverage is something that is utilized for risks mitigation. Trading volume goes high, the leverage automatically goes down, that's how the mechanism work. Plus, leverage varies depending on the assets. In this regard, ActivTrades are prudent, as those assets which are characterized by severe price fluctuations have lower leverage with an aim not making traders succumb to the temptation.

You've got tons of options to for risk-management and risk mitigation. Sizing your trades properly, making sure that you have stop loss and progressive stop loss orders are set-up correctly along with your positions, there's hedging available on the activtrader platform, and you must always check your portfolio frequently throughout the trading sessions if you have positions that are trading live in the market at that particular moment in time.
