Charts
Interactive charts are powered by TradingView's free widget. Candle data, indicators, and drawings are provided and computed by TradingView. We don't modify or proxy this data.
Technical signals
Our TA cards use standard indicators (RSI, MACD, EMAs, Bollinger Bands, ATR) computed on TradingView-sourced OHLC at multiple timeframes. Signal labels (Bullish / Neutral / Bearish) are a weighted aggregation, not a recommendation.
AI predictions
AI prediction cards use a hosted large-language-model that reasons over recent price action, indicator state, and news headlines. Outputs are probabilistic opinions, not forecasts. Confidence scores reflect model self-reported certainty and should be treated with healthy skepticism.
Paper trading
The paper-trading simulator marks positions to last traded price every 30 seconds. Fills assume zero slippage and a flat 0.10% round-trip fee. Equity, PnL, and leaderboard ranks are computed server-side from immutable trade records.
Known limits
- We do not provide tick-level or order-book data.
- Some illiquid pairs may show stale prices when source providers haven't updated.
- Reference fiat rates differ from interbank or retail rates by a spread we do not model.
