Question 1

Checking Data Coverage

Accepted Answer

1. Visit the **Data Coverage** page to see all available instruments 2. Each instrument shows: - Available timeframes - Date range (start → end) - Exchange source - Data completeness status

Question 2

Instrument Not Available

Accepted Answer

**Problem:** Your desired trading pair doesn't appear in the instrument list. **Solutions:** - Check if the pair exists on supported exchanges (Binance, Bybit) - Try the exact format: `BTC/USDT` (with slash), not `BTCUSDT` - Some delisted pairs may not be available - Forex pairs use Dukascopy data — check the forex instrument list - US Stocks use Alpaca data — 130+ symbols available

Question 3

No Data for Selected Period

Accepted Answer

**Problem:** The backtest period extends beyond available data. **Solutions:** - Check the data range in the configurator — it shows available dates - Adjust your period to fit within available data - Newer instruments may have limited history

Question 4

Chart Shows Gaps

Accepted Answer

**Problem:** The TradingView chart has missing candles. **Possible causes:** - The exchange was down during that period - Weekend/holiday gaps (normal for stocks and forex) - Data loading in progress — some instruments are still being loaded

Question 5

Slow Data Loading

Accepted Answer

**Problem:** Charts or backtests take a long time to load data. **Solutions:** - Large date ranges with small timeframes generate millions of candles - Try a larger timeframe (e.g., 1h instead of 1m for multi-year periods) - The system downsamples to max 50,000 candles for chart display
