The global recession which resulted in skyrocketing global inflation led to the emergence of energy and food crises in a number of countries. This increase in inflation was responded by tightening liquidity and increasing interest rates in developed countries. This situation has led to global financial market volatility, capital outflow, weakening of the exchange rate and an increase in the cost of funds. This condition was followed by a downward correction in the projected global economic growth. This has led to stagflation, namely the weakening of the global economy and has an impact on investment rates, especially users of online investment applications. Gradually, the reduced investment will also have an impact on Investment/Security Applications. The form of legal protection obtained by investors in the activity of buying and selling shares in online-based securities companies can be carried out in the form of preventive protection (prevention) and repressive protection (imposition of sanctions). As for preventive legal protection by the Financial Services Authority, namely the existence of rules to prevent violations that can cause losses contained in Law no. 21 of 2011 concerning the Financial Services Authority.
