# Journal and trading tools

The trade journal, study notes, prop-firm tracking and position sizing.

## Trade journal

Log your trades and review what worked: a calendar of results, breakdowns by
setup and time of day, and notes on each trade. Import trades from a file, or
connect a supported broker account in **Settings → Broker connections** to
sync them. Your journal is private to your account.

## Study

Keep notes, videos and a knowledge base next to your journal. You can connect
a Google Drive or Obsidian-style vault so your notes stay in your own files.

## Prop firm planner

Model a prop-firm plan before you pay for it: account fees, profit split,
your win rate and the firm's loss, drawdown and profit-target rules, to see
what a run of evaluations is likely to cost and pay.

## Kelly sizer

Turn your win rate and payoff into a position size. Most traders use a
fraction of the full Kelly size.

## Mean reversion

How stretched price is from its average, with the historical odds of it
reverting.
