Paper Trading is a sandbox that lives on its own account (flagged `is_paper`). You write an order ticket the way a broker asks for one: symbol, side, market or limit, volume — either in lots or as a fixed cash amount in your account currency — plus optional take-profit and stop-loss. A live chart with autocomplete sits next to the ticket so you can eyeball the levels before you commit.
A market order fills immediately at the current price. A limit order waits: a background resolver runs every minute and fills it the moment the price crosses your limit. The same resolver watches every open position's TP/SL against the 5-minute candle's high and low — so a wick that tags your stop closes the position, exactly like a broker would.
Open positions show a live, auto-refreshing P&L. You can close a position by hand at any time, or close part of it (Teilschließung) — a modal lets you pick the lots with 25 / 50 / 75 / 100 % presets and previews the realized result before you confirm; the rest of the position stays open. Every closed paper position becomes a real Trade row on the paper account, so the whole Onyx-Engine — patterns, R-multiples, risk-of-ruin, the Overview KPIs — runs on your simulation.
The account carries its own virtual capital: the page shows equity, starting capital, realized and unrealized P&L. You can edit the starting capital or reset the account (a full wipe) to start a fresh experiment.
What Paper Trading is good for — and where its limits are: - Rehearse a new setup risk-free. Run the setup for two or three weeks on paper first; the Overview + Patterns tabs on the paper account tell you whether it has an edge before a cent is on the line. - Pressure-test your TP/SL discipline. Because the resolver closes positions exactly on the levels you set, paper trading shows you what your rules *actually* produce — not what you remember them producing. - Learn the order ticket. New to limit orders or to sizing by cash amount? The sandbox is the cheapest place to make the beginner mistakes. - The honest limitation: paper fills are idealised. There is no spread, no slippage, no partial-fill queue, and a market order fills at the candle's close rather than the exact tick. Real execution is always a little worse. Treat a paper edge as the *optimistic* version of the real one — if it doesn't work on paper, it won't work live; if it works on paper, it still has to survive real fills.
In TradeOnyx the paper account is fully isolated (TRA-414): its trades, patterns, AI analysis and KPIs are never mixed into your real-money numbers, and a real-broker import can't land on it by accident. You switch to it from the account switcher in the header — it carries a gold Paper badge so you always know which account you're looking at.
The signature workflow: place a few paper trades for a setup you're unsure about, let the resolver run them to their TP/SL over a couple of weeks, then open the Patterns tab *on the paper account* and read the same Onyx-Engine verdict you'd get on real trades — without the real-money risk. When the experiment is done, hit reset and start the next one on a clean slate.
Paper Trading is a simulation for practice and analysis only. No real money changes hands, no order reaches a broker, and nothing here is investment advice.
