What's the strategy advice you wish you'd ignored?

Bad advice arrives wrapped in confidence: "always use 1:3 RR", "never trade Fridays", "indicators are useless", "price action is king". Some of it cost you months.

Share yours:

• the advice and who gave it
• what following it cost you
• the nuanced version you'd offer instead

This thread is the antidote to one-size-fits-all strategy advice.
