Turn $500 into $1,000.
Winning just 3 trades out of 11. Not by predicting better, but by sizing every trade with arithmetic instead of a feeling, so a losing win rate still ends the session in profit.

Discipline first. Strategy second.
You do not blow up because your entries are bad. You blow up because your sizes are guesses.
Most traders spend years hunting a better strategy. Meanwhile the size of every trade, the thing that actually decides whether you survive, gets picked by mood. Feeling confident? Go bigger. Just lost three? Go bigger to win it back. That is the whole story of a blown account.
Revenge sizing
Two losses in a row and the next trade is suddenly double. One bad entry now costs what four good ones made.
Scared sizing
After a drawdown you shrink to nothing, so the winner that finally lands is too small to repair anything.
Random sizing
No plan at all. Some trades 1%, some 7%, decided in the second before you click buy.
We replaced the guess with a number. Before every trade the tool tells you exactly what to risk, and that number already knows how many trades are left and how many you still need to win.
Three wins. Eight losses. Two very different endings.
Three wins out of eleven is a 27% win rate. At a 1:2 reward you need 33% just to break even, so this is a losing win rate. Flat staking goes backwards. The arithmetic does not. These are one setting of many; you pick your own in section 03.
The same eleven trades, sized two ways
Flat 1% per trade
$490.00
-2.0%, finishes down
Trade by Math
$652.84
30.6%, finishes up
Flat staking risks 1% of the opening balance on every trade. Trade by Math sizes each trade from what the session still needs. Identical entries, identical order, identical losses.
The only thing that changed was how much money sat on each trade.
Your session. Your numbers. Change anything.
Eleven trades needing three wins is one example. Run nine needing two, or twenty needing six, at whatever reward you actually trade. This is the real engine, the same code inside the MT5 panel, so every figure here is the figure the tool would give you.

Tap or hover any square to see what that setup needs and what it pays.
Read it diagonally. Go down the grid and the payout climbs, but so does the win rate you must hit. Go right and the session gets safer, and the gain shrinks.
Ignore the big numbers bottom-left. A 243× square means winning 5 trades out of 5. Tap it and you will see the chance of actually doing that is about 1 in 100. There is no free square. The useful settings are the ordinary ones, and you pick the trade-off that matches how you really trade.

Four steps. No arithmetic on your side.
- 01
Set up the session
Three numbers: what you are putting to work, how many trades the session runs for, and how many of them you need to win.
- 02
It tells you what to risk
One figure before every trade. On MT5 it converts that figure into lots for whatever you are trading. You never decide a size again.
- 03
Record won or lost
One click. The next size recalculates instantly from what is left. One undo button walks back a misclick.
- 04
Bank it and go again
Hit the win target and the session closes in profit, wherever those wins landed. The new balance carries into the next session.
In your browser, or on your MT5 chart.
The same engine behind both, down to the last cent. Use whichever suits the way you trade. Most people use both.
Web calculator
Sign in and start. Nothing to install.
- Runs in any browser: desktop, tablet or phone
- Any session shape you like: you set the trades, wins and reward
- Your sessions saved to your account
- Works for any market, any broker, any platform
MT5 panel
Advanced Money Manager, on your chart.
- A panel that sits on the chart you are trading
- Turns your risk into lots for FX, gold, indices, crypto and shares
- Drag the stop-loss line and the lot size follows it live
- Survives a restart, so your session is still there tomorrow
The panel does the money management. It does not place orders for you. You stay in control of every entry.
Android and iOS apps
The same calculator in your pocket. Size a trade and record the result from your phone while you are away from the desk, sessions synced to the same account. Free for everyone who has already bought.
The arithmetic does not care what you trade.
It works on anything with a win, a loss and a reward-to-risk number. That covers almost everything you can trade or invest in.
- Forex
- Majors, minors and crosses, with lots worked out per pair.
- Stocks
- Share CFDs and cash equities, position sized by risk.
- Investing
- Longer holds where size still decides the outcome.
- Indices
- US30, NAS100, GER40 and the rest.
- Gold & metals
- XAUUSD sizing without the usual lot confusion.
- Crypto
- BTC, ETH and altcoins, wide stops included.
Prop firm math
A mode built around challenge rules. Your profit target, your daily loss limit and your maximum drawdown become part of the calculation, so a session can never put you outside the rules. Included free when it ships.
What this is not.
Every tool in this corner of the internet promises you the world. Here is the plain truth about what you are buying, so nobody feels misled later.
- It is not a strategy and it will not find trades for you.
- You bring the entries. This decides how much goes on each one. A tool that sizes bad trades perfectly still loses money.
- A session can lose everything you put in it.
- If you do not hit your win target, the money allocated to that session is gone. All of it, not a slice. In the demo above, 2 wins out of 11 ends at zero. That is the trade-off for the upside, and you should only ever run a session you can afford to lose.
- It cannot fix a losing edge.
- The arithmetic turns a below-breakeven run into a profit inside a session, but across many sessions you still need a real edge. If you genuinely win 20% of your trades at 1:2, no sizing rule on earth saves you.
- It does not place trades.
- The MT5 panel calculates and records. It never sends an order. Every entry and exit is yours.
- Past results are not a promise.
- The figures on this page are arithmetic, not a forecast. They show what the sizing does given a win count, not how often you will hit it.

Straight answers.
01Do I need to be good at maths?
No. You never see a formula. You enter three numbers once, then the tool shows you one amount before each trade and you click won or lost. That is the entire job.
02Is it locked to 11 trades and 3 wins?
No. That is just the example on this page. You choose how many trades a session runs for, how many of them you need to win, your reward per trade and your starting money. Nine trades needing two wins, twenty needing six, anything you like.
03What broker or platform do I need?
The web calculator works with any broker on any platform, because it just tells you the amount to risk. The panel needs MetaTrader 5, which almost every broker offers free.
04Can I use it on a prop firm challenge?
Yes, people do. A dedicated prop firm mode that builds your daily loss limit and drawdown into the calculation is coming, and it is free for everyone who has bought.
05Is this an auto-trader or a signal service?
Neither. It never places an order and it never tells you what to buy. It manages how much money goes on the trades you have already decided to take.
06What happens if I miss my win target?
The session ends and the money you allocated to it is lost. This is the honest downside and it is spelled out above. Only ever run a session with money you can afford to lose.
07One payment really means one payment?
Yes. $49 once, including every update we ship afterwards. There is no subscription and no renewal.
08Which account can I use it on?
Your licence covers one MT5 account at a time, live or demo, and you can change which account that is from your dashboard whenever you need to.
09Can I get a refund?
Within 14 days, yes. Email us and we refund it. After that the sale is final, which is why the honest section above exists.
