yes there is something like a cult-mentality among some "followers".
The nice thing with trading is IF they continue trading, sooner or later they will realise they were taken for a ride : their time is the most precious thing. This one only realises after sorting out the profitable trading aspects. Without counting the flattery cult leaders use when necessary: down the line this will be the biggest source of anger against their "gurus" aka "cult-like" leader. Till they realise or understand : they are following happily, attacking any critical voice against their "cult-leader". However, sooner or later reality will come.
Well it might never come because you can stay in denial for a long time. There are people who have been trying to day trade for over a decade and still going from guru to guru.
Just look at some recent posts in the "Topsteptrader????" thread in this forum. A guy who spent years in prop firms said he had around 20 guys from ET come into his firm to trade......... all claimed on ET that they never lost money but none of them made money at his firm. And even worse.......... some even came back to ET afterward and continued the "never lose" game. People can stay in denial for a long time.
