Investing journal guides for people who hold for months, not minutes

RB Trading 8 October 2026 4 min read

Most journaling advice is written for day traders. Investors need the same discipline on a slower clock: a written reason for every buy, a level that says you were wrong, a size worked out from a risk budget, and a review that judges decisions rather than prices. These guides show how, each with worked numbers.

Every guide here follows the same idea. Treat each holding as a decision you can grade later. That means writing down what you expected before you buy, measuring the result in R (the result divided by what you planned to risk), and reviewing on a schedule rather than whenever the market makes you nervous.

How to journal long-term stock positionsThe four lines to write before you buy, and why R works on a fourteen-month hold. Position sizing for investorsRisk budget per idea, a cap per holding and total portfolio heat.

The 50/200 EMA trend filterWhen to add, when to hold and when to stop buying, with the EMA maths. Journaling trims and exitsFive exit reasons, size-weighted R and the three-month check.

Reviewing

What the journal does for investors

The RB Trading journal started as a tool for active traders, and that shows in the parts investors find most useful:

Equity curve in the RB Trading journal with drawdown from the peak plotted underneath — The equity curve, with drawdown from the running peak plotted underneath (demo account).

Several accounts, one login. Keep a long-term portfolio apart from swing trades or a prop challenge, then view them combined.
Stocks with a cash leverage basis, so buying-power warnings match an ordinary investing account.
Split entries. Two or three planned entries, each sized from one total risk percentage, saved as one position.
Partial exits with size-weighted R, so a position sold in thirds gets one honest result.
Strategy tags, notes and screenshots on every position, plus hold-time analysis once you log close dates.

These guides are education, not personal investment advice. Examples use made-up tickers and round numbers so the arithmetic is easy to follow.
