Everything on the site, explained in one place — the calculator, the trading journal, prop firm tracking, and the free tools.
Download as PDFKingstone is a free position size calculator and trading journal built around one idea: trade on a plan, not a feeling. It calculates exactly how many lots to trade so a stop-loss hit always costs a fixed, known amount — then logs every trade automatically so you can see your real win rate, risk:reward, and where your edge actually is.
Nothing on Kingstone is financial advice — it's a set of tools for managing risk and reviewing your own trading history.
Available at /calculator/ — no login required. Enter your account balance, your max risk per trade, your entry price, and your stop-loss price, and it tells you the exact lot size to use.
Max risk has two linked fields — a dollar amount and a percentage of your balance. Type into either one and the other updates automatically, so you can think in whichever unit makes sense to you.
Supported instruments include the majors (EURUSD, GBPUSD, AUDUSD, NZDUSD, USDJPY, USDCHF, USDCAD), plus XAUUSD (gold), US30, USTEC, and USOIL — each with the correct pip size and contract size built in.
Log in at /app to use the trading journal. Once inside, you can create multiple separate accounts — for example a Real account, a Demo account, and a Prop Firm Challenge — each with its own balance, its own risk settings, and its own completely separate trade history.
Pair Settings (pip size, contract size) are shared across all your accounts, since they're just facts about the instruments — everything else (balance, trades, limits) is separate per account.
The Dashboard tab is your account's home screen. It's split into a few parts:
Set your Starting Balance and your Max Loss per Trade — again as a linked $ / % pair, so the Trade Log's automatic lot sizing always matches your actual risk rule.
Total Trades, Win Rate, Average R:R, Current Balance, Winning/Losing Trades, Total Commissions, Total Net P&L, and Max Drawdown — all calculated automatically from your logged trades.
Equity Curve, Win/Loss split, Net P&L by Pair, Net P&L by Strategy, and Win Rate by Strategy — so you can see not just whether you're profitable, but exactly where the profit (or loss) is coming from.
A written summary of your trading for a chosen period (this week, this month, etc.), flagging patterns like weak strategies or recurring mistakes mentioned in your trade comments.
If you're trading a funded/prop firm account, scroll to Prop Firm Limits in Account Settings and enter your firm's two rules as percentages — for example 10 for a 10% max drawdown limit, and 5 for a 5% daily loss limit. Leave either blank if it doesn't apply.
Once set, a Prop Firm Status card appears on your Dashboard showing:
Both update automatically from your logged trades — you only ever enter the two limit percentages your firm gave you.
Below Prop Firm Status, the Trade Calendar shows a full month at a glance, with each day colored green or red based on that day's closed-trade net P&L. Use the arrows to move between months.
Click any day to jump straight into the Trade Log, filtered to just that date — click the same day again, or the "Clear" link that appears, to remove the filter.
Click + Add Trade to log a new trade. Each row has these columns:
| Pair / Side / Strategy | Which instrument, Buy or Sell, and your strategy tag — pick from the list or choose "+ Add new strategy…" to create your own. |
| Entry Date / Entry / Stop | When you entered, and your entry and stop-loss prices. |
| Lot (auto) | Calculated automatically from your Max Loss setting and this pair's Pip Settings. Type a value here yourself to override it for this one trade. |
| Exit / Exit Date | Leave blank while the trade is still open. |
| R:R / Commission | Risk:reward ratio, calculated automatically, and any commission you paid. |
| Gross / Net PnL / Net % | Profit before and after commission, and net P&L as a percentage of balance. |
| Comments | Notes to yourself — these feed into the Trading Review's mistake detection. |
Filter by Pair, Strategy, Side, Result (wins/losses/open), or a Min/Max Net P&L range — combine as many as you like, and hit "Clear filters" to reset. Sort by most recently added, or by entry date.
Click the trash icon on any row — you'll be asked to confirm before anything is permanently deleted.
This tab defines the math behind auto lot sizing for every instrument you trade: Pip Size, Contract Size (in units), and whether the Quote currency is USD. New accounts start with 11 common instruments already configured, so auto lot sizing works from your very first trade.
Click + Add Pair to add a new instrument, or edit any existing row directly. Renaming a pair automatically updates every trade already logged under its old name.
All available at /tools/, no login required:
On Chrome or Edge (Android or desktop), look for the Install App button on the homepage or journal header — it adds Kingstone to your home screen or app list like a native app.
On iPhone, Safari doesn't support this automatically — tap the Share icon, then "Add to Home Screen."
Is my data private?
Yes — every account is protected so only you can see your own trades and settings.
Do I need to fill in every field on a trade?
No — leave Exit and Exit Date blank for open trades. Everything else recalculates automatically as you fill it in.
Is this financial advice?
No. Kingstone is an educational risk-management and journaling toolset, not a source of trade recommendations.
