📈 Signals
The Signals panel draws technical indicators, comparison series and benchmark curves on the FX chart. LibreFolio computes the indicators from the pair's stored rates.
🛠️ Add a signal
- Click the Signals bar above the chart to unfold the panel.
- Pick a signal from one of the three dropdowns: Technical Indicators, Data Comparison or Synthetic Benchmarks.
- Adjust its parameters on its card: the chart follows.
- Drag the cards to reorder them; 🗑️ removes one.
The signals you add are kept with this pair's chart settings.
🧮 Technical indicators — 9 for FX
Nine indicators work on FX rates. Follow the links below, or click 📖 on a card, for the math behind each one.
| Family | Indicators |
|---|---|
| 📈 Trend (3) | EMA · SMA · KAMA |
| ⚡ Momentum (5) | RSI · MACD · ROC · Stochastic RSI · PPO |
| 🌊 Volatility (1) | Bollinger Bands |
🤔 Why only 9? — the other indicators need more than a daily rate
FX rates have one value per day, with no high, low or volume. The other indicators need those fields, or measure portfolio-style risk, so they are available on asset charts only. The full list is in Technical Indicators — Financial Theory.
🔍 Finding an indicator
The Technical Indicators dropdown is a tree grouped by family (trend, momentum, volatility), with
a search box on top: type to filter every family at once. The arrow keys and Enter work too.
Screenshot coming: the grouped indicator tree open on the FX Signals panel.
💱 Data comparison
- 💱 FX Pair — another of your pairs, e.g. GBP/USD next to EUR/USD. In the list, 👑 marks this page's pair and 📌 a pair already used by another signal.
- ↔️ Asset Comparison — an asset's price next to the rate.
A comparison card has buttons to sync the compared pair or asset and to open its page. In % view both curves start at 0 %, so their moves compare directly.
📐 Synthetic benchmarks
Reference curves built from parameters alone, with no market data: Linear Growth, Compound Growth and Sine Wave.
🎛️ Read a signal card
- 📖 opens the indicator's theory page; hover a parameter for help.
- A badge counts the data points loaded for the signal.
- A spinner turns while the signal is computed. Then an icon may report a problem — hover it for
the details:
- grey ℹ️ — a small caveat;
- amber ⚠️ — computed with caveats, such as gaps, a short warm-up or data that starts after the period;
- red ⚠️ — not computed, for example because the history is too short.
If a card reports missing data, syncing the pair usually fills the gap.
