Three steps. Most people skip the third.
Nothing here tells you what to buy. It tells you how much, and whether the way you have been trading is actually working.
- 01
Size it
Decide what you are willing to lose. The position size follows from that, rather than from a round number that felt about right.
- 02
Take it
Place the trade with a stop you chose deliberately beforehand — not one you talk yourself into once the position is already red.
- 03
Review it
Log the result. After enough trades you stop guessing whether your approach works and start knowing your real win rate.
Know what you are risking
In money, before you enter — not as a feeling about how confident you are in the setup.
Size the position correctly
The arithmetic that turns a risk budget and a stop distance into an exact number of shares, lots or contracts.
Find out if it works
A journal replaces the story you tell yourself about your trading with your actual win rate, average R and drawdown.
Markets
Crypto prices and the seven major currency pairs, each one click from being sized. Every number says where it came from and how fresh it is.
Journal
Log what you actually did and the page works out your real win rate, your average R and the drawdown you have already survived. No account — it stays on your device.

Every result the calculator produces links back to the idea behind it.
