Most trading advice focuses on strategy: which indicator, which setup, which timeframe. Less discussed but arguably more important is the routine around the strategy, the daily habits that determine whether it actually gets executed consistently or abandoned under pressure.
1. Before the session
A short pre-market routine, checking the economic calendar for scheduled releases, marking the prior session's key levels, noting any overnight gaps or news, takes 15-20 minutes and eliminates most of the "I didn't realize there was a Fed announcement" category of mistakes.
2. During the session
Deciding position size, entry criteria, and stop-loss levels before the session starts, rather than in the moment, removes emotion from decisions made under time pressure. A written (even brief) plan for the day's setups is easier to follow than a mental one.
3. After the session
The habit that actually compounds improvement over time is reviewing not just the outcome of each trade but whether the plan was followed. A losing trade taken exactly according to plan is a different problem than a losing trade taken on impulse, and conflating the two prevents traders from identifying which mistakes are actually costing them money.
