What changed in the app.

Paired sessions and rooms by topic

Backtesting together is now called a paired session, and lives in Sessions, Paired sessions tab. You pick the mode there, data collect or strategy test, just like a personal session; in a strategy test, your partner sees the rules too.

A room becomes a topic that gathers paired sessions:

• Its creator invites their friends.
• A paired session can be filed there if both its players are members.
• The room's page shows each member's result: sessions played, trades, P&L, win rate.
• The creator opens read-only, session by session, the sessions they want reviewed.

What doesn't change: your existing paired sessions are all there, without a room.

TradeChart moves to TradingView charts

TradeChart's simulator now uses Advanced Charts, the charting library from TradingView, used under licence.

What changes for you: TradingView's drawing tools and indicators, right in your backtest. Your drawings are kept with your session, and in a paired session, they appear on your partner's screen. To move forward or back one candle: Shift+→ and Shift+←.

What doesn't change: your data, your sessions and your analytics. The server still computes your P&L on its own, and the replay never shows a candle beyond the moment you've reached.

Crypto arrives, and it trades at the weekend

Bitcoin, Ether, Solana and XRP replay in minute data. Unlike forex, these markets don't close: your sessions run through Saturday and Sunday.

• 4 instruments: BTCUSD, ETHUSD, SOLUSD, XRPUSD.
• Trading 24 hours a day, 7 days a week.
• One period is still missing, from September 13, 2025 to March 25, 2026: the data wasn't reliable there.
• Crypto volume is hidden, as on forex.

Cleaner candles from 2021 to 2024

On eight forex pairs, the 2021 to 2024 candles were replaced by a source with more faithful wicks. Your already closed trades keep their result.

• EURUSD, GBPUSD, AUDUSD, NZDUSD, USDCAD, USDJPY, EURJPY, GBPJPY.

A new login screen

Logging in and signing up each have their own screen, instead of two tabs.

The journal and session statistics

• A “Result” column in the journal: winner, loser or break-even.
• A session's Statistics tab rearranged, with three more blocks.
• A session's confluences follow the same rules as the overall analysis.

Many more analytics

• Performance by market session, on a 24-hour timeline.
• Results by pair, direction and timeframe, with their confidence interval.
