Trade Architect

One form for the whole trade: position size, risk and reward in your account currency, R:R, and margin — with the pair charted and your entry, stop and target drawn on it.

A $10,000 account risking 1% on a EUR/USD long — entry 1.10000, stop 1.09500 (50 pips), target 1.11500 (150 pips) — sizes to 0.200 standard lots (20,000 units): risking $100 to make $300 at a 1 : 3.00 risk-to-reward. At 1:30 leverage that position ties up ≈ $747.67 in margin (today's ECB rate). One form drives position size, risk, reward, R:R and margin together, so they can't contradict each other.As of Oct 20, 2026 · ECB reference rates via frankfurter.dev

What the Trade Architect does

It chains the math of four separate calculators into one view so they can't contradict each other: position sizing from your risk percentage and stop distance, risk:reward from entry/stop/target, pip value in your account currency, and margin at your leverage. The chart draws your entry, stop and target on the pair's recent price so you can see the trade's geometry, not just its numbers.

How the levels are drawn

The chart draws the pair's daily closing prices for roughly the last 90 sessions, from European Central Bank reference rates via frankfurter.dev. Your entry, stop and target are overlaid as dashed price lines. The chart is daily, not intraday, so treat the levels as planning context, not a tick-precise quote.

FAQ

Is the Trade Architect free and signup-free?

Yes. Every ForexFin tool runs in your browser with no account. Your inputs are saved locally on your device, not on a server.

Which numbers update the chart?

Changing the pair reloads the price chart; changing entry, stop or target moves the dashed levels instantly without re-fetching data.

Why does the Trade Architect sometimes show a line instead of candlesticks?

It draws ECB daily reference rates, which publish one price per day, so there is no open, high or low to build a candle from. The line shows the daily close.
