What should you focus on in the first 90 days of trading?
The short answer
The first 90 days are for building a process you can repeat, not for producing a result. Focus on following a written plan, recording what actually happened, and reviewing the gap between the two.
A new trader often measures the first 90 days by the account balance. That number moves for reasons that have nothing to do with skill: market conditions shift, a single session runs hot or cold, and small samples swing. None of that tells you whether your process is sound.
What you can measure honestly in this window is whether you did what you said you would do. Did you decide your risk before the session instead of during it? Did you wait for the setup condition you defined instead of entering early out of impatience? Did you exit when your plan said to exit, win or lose? Those are the questions a 90-day process answers. The account balance is a side effect of the process, not a measure of it.
This is you vs. you.
The comparison that matters in this window is between the plan you wrote and the decisions you actually made.
How do you build a routine that survives the full 90 days?
The short answer
A routine survives 90 days when it is written down, small enough to repeat daily, and reviewed on a fixed schedule rather than only after a hard session.
Start with a short pre-session checklist: the setup conditions you are looking for, the amount of risk you decided on before the market opened, and the point where the idea is no longer valid. Write it in the same place every time so it is a reference, not a memory exercise.
During the session, the routine’s job is to slow you down. If a trade does not meet the conditions you wrote, it is not your trade that day. If it does meet the conditions, you still size it according to the risk you already decided on, not according to how confident you feel in the moment. Build a Repeatable Trading Routine walks through this pre-session and in-session structure in more detail.
After the session, log what happened against what you planned. Over 90 days, this log becomes the clearest record you have of where your process is strong and where it drifts. A routine that only exists in your head rarely survives a stretch of losing trades or a stretch of easy wins, both of which tempt a trader to abandon the plan.
Base hits build accounts. A 90-day window is not long enough to need a large outcome from any single session, and trying to produce one tends to break the routine you are there to build.
What should you review at the end of each week during this period?
The short answer
Review adherence before you review outcome. Check whether you followed your own rules, then look at the pattern of decisions across the week, not any single result.
At the end of each week, start with a simple adherence check: how many sessions did you follow your pre-session checklist, and how many times did you deviate. A deviation is not automatically a problem to punish, but it is information. If the same deviation shows up repeatedly, that is the behavior to address the following week, not the account swing that resulted from it.
Next, look at how you handled risk when things did not go as planned. Did the amount you risked stay the same as what you decided before the session, or did it grow after a loss in an attempt to recover faster? Growing risk after a loss is one of the more common ways a 90-day process gets derailed, because it ties your next decision to your last outcome instead of to your plan.
Finally, separate a bad process decision from a losing trade. A trade can lose money while every decision inside it followed the plan, and a trade can make money while the process behind it was undisciplined. Reviewing the decision, not just the result, is what lets you sharpen next week’s plan with real evidence instead of a reaction to how the week felt. A Bad Trade and a Losing Trade Are Not the Same goes further into that distinction, and What to Measure in Your First Year Besides Money extends this review habit past the 90-day mark.
Take it with you
- Use the first 90 days to build a repeatable process, not to chase a result.
- Write your pre-session checklist and risk decision before the market opens, and keep them the same.
- Review adherence to your plan before you review the account outcome.
- Separate a losing trade from a bad decision so your weekly review stays accurate.
