I also totally agree with this. People think trading can be an easy way to make money but this is not the case for most traders. Any trader that has been trading for like a year or two but still losing, such person should better stop trading.
I always post that trading is not gambling but it is very risky like gambling.
Trading is also dangerous but there's a system to it that makes it profitable than gambling. The problem why a lot of traders end up losing is because they don't follow the rules. When trading the financial market it's important to always remember that it's a step by step process. Trying to make money fast is going to make you lose money rapidly. But like you said it's best to stop when you are losing consistently
