PAPER TRADING ON AXIOM, GMGN & PADRE
Quick Buy from supported discovery pages, paper-trade with a compact in-chart widget, see entries and exits on the chart, and review every result with realistic P/L.





LIVE DIRECTION + SAVED REOPEN LINKS
Open position tabs show a green or red direction circle and live open P/L in the tab title. The widget also keeps the P/L direction of your other open coin tabs visible.
Keep the supported coin page open for live market-cap and P/L updates.
Your position and exact coin link remain saved locally, but live updates pause.
Come back the next day or week and resume from the coin's current market cap.
JOURNAL EVERY ENTRY
Beginners improve faster when they review the decision, not only the final P/L. Add your reason to an open coin, then find that note beside its buy entry in Transaction History.


DIFFERENT LAUNCHES, DIFFERENT FLOORS
Choose a floor below the market cap where these coins usually begin. For example, if they commonly start around $5K, try a $2.5K floor, about 50%. A sensible floor makes downside estimates more realistic, while upside still follows normal market-cap movement.
Example before buy and sell taxes.
REALISTIC PRACTICE, HONEST LIMITS
Paper-trading results are estimates, so they will not be 100% identical to live execution. They are still useful for practicing decisions, reviewing patterns, and building trading intuition without risking real funds.
Match the floor to the usual launch range of the coins you practice to make downside calculations as realistic as possible.
A $0 floor or a rough estimate still lets you practice entries, exits, position sizing, and review your decisions.
Use the results to compare choices and develop intuition, not as a guarantee of exact live-market execution.
THE REAL EXTENSION
Practice the decisions around entries, exits, costs, and review. It never executes real orders or promises results.
Quick Buy is enabled by default on supported Axiom, GMGN, and Terminal/Padre discovery pages, so a virtual entry is only a click away.
Paper-buy, add entries, and scale out from the compact chart widget with saved amounts, a custom buy, percentage sells, and SOL or USD display switching.
Orange B and S markers keep entries and exits visible on the chart, while Average Buy and Average Sell lines show the position at a glance.
Add to the same coin more than once. Individual buy lots stay in the ledger while the position shows a weighted-average entry market cap.
Keep a small floating balance and open P/L view above the chart, then expand the trading widget only when you need its controls.
Fetch the current public SOL/USD spot rate from Coinbase with Live, or set the conversion rate yourself for SOL and USD balance displays.
Filter the trading history, review buy and sell records, attach a journal note to each position, and return through its saved platform link.
Follow realized balance after every sell, inspect recent sell results, and review trades, wins, losses, win rate, hold time, and net P/L.
Choose Default, Graphite, Matrix, or the optional Phantom-inspired appearance without changing how the paper-trading simulator works.
Virtual trades, settings, themes, and preferences stay in Chrome storage. Export or import a backup, clean old history, or use Fresh Start.
INSIDE PAPERTRA.DE
The chart widget leads. The popup keeps positions, realized-balance performance, themes, and simulation settings organized.

Scan wallet totals, open coins, weighted-average and current market caps, taxes, journal notes, percentage sells, and position P/L in one view.

Follow realized balance after each sell, review recent results, and switch between trade, monthly, and chart views.

Choose your theme and money display, then tune Quick Buy, taxes, delays, sounds, widget amounts, and local backups.
SOL/USD YOUR WAY
Use Coinbase's public SOL/USD spot rate with the Live button, or enter a custom conversion rate. Switch SOL and USD displays without changing the underlying virtual trades.

QUICK BUY
Quick Buy is enabled by default on supported Axiom, GMGN, and Terminal/Padre discovery pages. Use your saved paper-buy amount without opening the full chart first.

ON-CHART TRADE CONTEXT
Orange B and S markers show virtual entries and exits. Average Buy and Average Sell lines keep both reference levels visible as the market moves.

DEFAULT, GRAPHITE, MATRIX + PHANTOM-INSPIRED
Choose a clean Default view, darker Graphite, green Matrix, or a playful Phantom-inspired layout. Themes change appearance only; your local paper-trading data and behavior stay the same.
Phantom-inspired is an unofficial visual theme and is not affiliated with Phantom.
See virtual entries and exits directly on the chart.
Keep Average Buy and Average Sell reference levels visible.
Keep the reason for a trade beside its position and history.
Export, import, clean history, or confirm a Fresh Start.

FLEXIBLE PRACTICE BANKROLL
Fresh Start clears positions, notes, history, Journey, stats, and your current balance, then lets you begin again with values you review first.
HOW P/L WORKS
Positions use market-cap movement plus your configured buy and sell taxes. Results remain an educational simulation, not a promise of live execution accuracy.
New buys are tracked as individual lots and summarized with an average entry market cap.
Sold cost and profit move into realized P/L while the remaining position stays in open P/L.
An optional floor gives low-cap downside a more realistic zero point while preserving normal upside.
FROM WATCHING TO REVIEW
Visit an Axiom, GMGN, or Padre coin page. The extension reads the active coin information already visible in the tab.
Use custom buys, add entries, and scale out with percentage sells after any configured delay.
Check open and realized P/L, history, journal notes, and Trading Journey performance.

DESIGNED TO KEEP REAL FUNDS OUT OF REACH
For each simulation, papertra.de reads the coin and market-cap data already displayed in your supported browser tab. It does not connect to a wallet, request wallet keys, or submit real buy and sell orders.
Trade simulations use coin-page information visible on Axiom, GMGN, or Padre.
Your balance, simulated trades, positions, history, journal notes, themes, and settings stay in Chrome extension storage.
Outside supported trading tabs, the extension contacts papertra.de only to check for available extension updates.
FAQ
No. It is an educational paper-trading simulator. Buys and sells update a virtual balance and local trade ledger; they never submit an order or connect a wallet.
The extension works with supported Axiom, GMGN, and Padre coin pages in Chromium-based browsers. It reads the coin and market-cap information already visible in the tab.
The optional floor becomes the downside zero point for a new position. At $0, standard market-cap movement applies. Above $0, downside between entry and the saved floor is stretched to −100%, while upside remains unchanged.
Balances, simulated trades, positions, history, journal notes, settings, themes, and preferences are stored locally through Chrome extension storage. They are not uploaded to a papertra.de account or cloud database. You can export a backup and import it later.
