Trading Review Companion
Write down every thesis. Let your past self become your best coach.
A stock compounding at 15% annually has a daily profit probability of just 50.02% — almost indistinguishable from a coin flip. Trading is never about any single outcome — it's about having enough records to validate your decision process. Markets don't reward effort, they reward capability — and capability comes from traceable decisions and honest reviews. Write, review, then compare with a partner — that's where the gap begins.

Reviewing isn't optional — a loss you didn't learn from is just a loss. Log every market thesis on one timeline, then compare side by side with a partner. History doesn't repeat, but it rhymes.

The Investor's Path
Markets don't reward effort, they reward capability. At the highest level, investing is less about financial knowledge and more about psychology. Know yourself before you try to know the market.
Investment Identity & Awareness
Not knowing whether you're a value investor or a price speculator is the root cause of many losses. Correct thinking doesn't guarantee profits, but wrong thinking virtually guarantees long-term losses.
Position Sizing & Survival
Offense determines your ceiling, but defense determines how long you stay in the game. A 25% drawdown requires a 33% gain just to break even — beyond that point, recovery becomes exponentially harder. Survival is the only prerequisite for compounding every edge you have. A 25% stop-loss on stocks and 5% on leverage are non-negotiable lines.
The Review Methodology
Top-down: news → global → index → sectors → individual stocks → update plan. Reviewing is when System 2 activates — the deliberate, energy-hungry thinking mode that actually corrects biases.
You don't have to trade alone
Trade Basic's real value isn't just recording — it's putting your judgment and your partner's into the same review rhythm. System 1 makes snap decisions, System 2 corrects through review — and the loop itself is the engine that builds capability.
Account-level sharing
Turn on diary sharing for a partner link and both sides can compare history and new entries. Stock holdings are never exposed — your cards stay face-down.
Same-day side-by-side
Put both diaries next to each other on the same date. See who caught the key move and who missed the risk. No more arguing with vague impressions — let the written record speak.
AI can join the table
Issue a scoped API key to a partner account so an external agent can create diaries without inheriting full web access. Machine judgment plus your intuition — each covers the other's blind spots.
From losses to consistency: turn process into edge
Success isn't measured by any single outcome — it's whether your decisions produce stable profits across enough repetitions. Let go of individual results and focus on decision quality.
01
1. Record your thesis
Write down your rationale, risk assumptions, and trade plan while the market is still live. Don't wait until after the close — memory will rewrite the script for you.
02
2. Identify biases
Compare execution results against your original hypothesis. Remember: making money once doesn't mean you've matured — a lucky profit can create the illusion of skill. Determine whether the decision was flawed or whether it was just variance. A correct process can still produce temporary losses.
03
3. Define rules
Turn corrections into concrete, executable discipline rules. Sunk cost is never a reason to hold — learning to fold is the hardest and most important skill in investing.
04
4. Validate long-term
Review rule effectiveness continuously. The ability to maintain discipline after consecutive losses is what separates novices from mature traders. Verify positive expectancy with at least 30 samples — one trade is random, a large sample is meaningful. The best starting hand in poker wins over 80% of the time — but still loses nearly 20%. Always leave room for error.

Your toughest opponent is never the chart — it's yourself
Log InStart logging today, review weekly, and bring in a partner when you're ready to stress-test your market read. When you're tilting, the prefrontal cortex shuts down and the amygdala takes over — System 1 makes snap judgments while System 2 gets dragged along. The only antidote is a plan written in advance and enough records to force System 2 online when you need it.
Step 01
Record
Capture your rationale, risk assumptions, and stop-loss plan before every trade. Setting your stop before entry is non-negotiable.
Step 02
Review
Compare outcomes with your original thesis. Separate decision flaws from random variance — not every loss means you were wrong.
Step 03
Refine
Convert feedback into executable rules and verify positive expectancy with enough samples. Get the process right, and the results will follow.
