I’m afraid some of them get in from this forum, because others see people here posting it, and imagine that it must be true, and start repeating it.
If it’s not corrected, it becomes self-fulfilling.
That’s why there’s so much rubbish around. There’s no quality control (not just here - in any forum), which is why learning to trade from “online sources” is a disastrous approach.
If you read through “TomCooper’s” other posts, you’ll see exactly what I mean. (I don’t recommend it, though!).
