If yes what are the sign to know that one is becoming a trading addicts?
Yes, trading is addictive, but the only difference is that its addiction is not as rampant/tough as that of gambling and others.
Trading can be as addictive as gambling. After they lose such amount of money, they may think of changing. There are reasons there are also rehabilitation centers for people that are trading.
That's very incorrect. As I said earlier, trading can be addictive as well, just like any other thing you can think of. Once you do it uncontrollably, you are addicted to it. But the addiction to trading can never be compared with that of gambling. When have you heard that people and organisations are so worried about trading addiction? It's not even a popular discussion. Or when have you seen regulations mandating a self-exclusion feature on trading platforms? That should speak volumes on its own. People have better control over the addiction of trading than gambling, so we don't compare their magnitude as the same.
