Overestimated, overused forex methodology

Trading Discussion
1

I just wondered what people felt was the most overestimated or over used methodology/idea in forex trading. Very simple and short answers are ok. I’m looking for terms, words or methods used commonly that you think are of very little or no use in attempting to be a profitable trader.

Cheers

“Cut your losers.”

Sounds good, but this phrase actually suggests a trade is open without setting a stop-loss. Or if there is a SL, it is based on capital preservation only, taking no account of TA. Bad.
