What it does

Think in percentages, not hunches.

Capital growth
Simulate growth cycle by cycle from your starting capital and a % per cycle. Optional risk reduction and tax keep the plan realistic.
Position sizing
Position size and loss limits as a percentage of your balance, so they scale with your account — leverage, contract value and spread included.
Weekly journal
Log results at the end of the day or the week — no daily ritual required. Deposits and withdrawals update your balance.
Milestones
Capital levels where you plan to withdraw a part of your profit, with progress you can see at a glance.
Calculators
Compound interest, risk/reward, points to money, percent change and more. Your last inputs are remembered. Try them online.
Accounts
Keep separate accounts in their own currencies. Reference exchange rates convert instrument currency to your account currency.
Know your risk

One number before every trade. Build better habits.

Growstones is a planning and journaling tool. It does not connect to brokers, does not place orders and does not provide investment advice. Simulations are illustrations based on the numbers you enter, not forecasts. Trading involves risk of loss.
