What moves it
ECB and Fed rate differentials, inflation prints on both sides, and US labour data are the main scheduled inputs.
A trading reference platform
Trading mechanics, math, and pre-trade tools.
Mechanics explained from first principles. Calculators independent of any broker. The numbers behind a position, worked out before it is placed.
How it works
Three steps from mechanics to numbers
Understand the instrument. Run the numbers on the inputs you choose. See how price, cost and risk fit together before any position is placed.
What TradeBien is
A pre-trade platform, not a signal service
A reference for the mechanics of leveraged trading: how instruments work, what a position costs and risks, and the calculations behind it, worked out on stated inputs before anything is placed. The results hold for those inputs; they do not say whether a trade is a good idea, or how a broker will fill it. Education and tools are integrated, not separate features. No trading advice. No signals.
- Mechanics-basedCalculations derive from how instruments actually work. Not from any broker's preferred figures.
- Education onlyThis platform explains and calculates. It does not advise, signal, or recommend.
- Pre-trade onlyEducation and tools for the stage before a position is placed.
How to use the platform
Look up. Calculate. Compare.
Look up the instrument, run the calculations, then see how price, cost, volatility, and risk fit together for one position, before any order exists.

Run the calculations
Pip value, margin and position size from your own inputs, independent of any broker's quote.
$5K · EUR/USD · 30-pip stop · 1% risk = 0.16 lots
Put the numbers together
Set price, cost, volatility, and risk for the same position side by side, on the same assumptions.

The pre-trade snapshot
Price, cost, volatility, and risk — in one view
Price, cost, volatility, and risk for one position, side by side. Switch between the four instruments using the tabs. Illustrative price levels, not a live feed.
1.1253illustrative level · not a live price
illustrative range 1.1218–1.1288
The numbers · 1 lot
| Pip value | $10.00 |
| Margin at 1:100 | $1,125 |
| Long swap/night (illustrative) | −$7.00 |
| Round-trip spread (illustrative) | $8.00 |
Volatility context
70pips · illustrative ATR
An assumed daily average true range for illustration, not a measured average; read the live figure from a daily ATR (14 periods is TradingView's default).
Risk frame · $5,000 account
A 30-pip stop on a 1-lot position risks $300 at the stop price — 6.0% of equity.

Work out the numbers first. Do not assume them.
TradeBien is the pre-trade layer between the idea and the execution.
Tools
All 5 →Three calculators and two worked examples. The arithmetic of a position, set out before it is placed.
Pip value, margin and prop-challenge maths calculated from your inputs, plus spread cost and leverage risk worked through on EUR/USD. The arithmetic follows from instrument mechanics, independent of any broker quote; the spread, leverage and stop-out levels in the examples are illustrative broker settings, and the prop cost figure rests on the fee you enter and an assumed pass-rate band.

Three places to start
Common pre-trade questions — two core concepts and one worked calculation.
- Article— core conceptWhat is a pip?The standard unit of price movement on a currency pair. On EUR/USD, on a USD account: $10 per pip per standard lot.
- Calculator— calculatorMargin calculatorRequired margin at any leverage. EUR/USD 1 lot at 1.1253 and 1:100 needs $1,125.
- Term— core conceptLeverageThe ratio of position size to the margin held. 1:100 means $1 of margin controls $100 of position.
