Data sources and methodology
Lzzo.com presents market information with its source and freshness status. Refreshing a page does not mean the price was verified on the exchange at that moment.
Price statuses
- Verified: a quotation received from the provider. Check the source and timestamp.
- Last price: while markets are closed or the source is unreachable, the last verified quotation is kept with its original timestamp. Unsourced catalogue figures are never shown as prices.
- Model: a value calculated from another price and a weight/rate formula; not a buy or sell offer on the physical market.
- No data: the source could not be verified. Missing historical candles or indicators are not generated.
Sources and units
Crypto quotations come from Binance; assets not traded on Binance use verified Yahoo Finance symbols, or DefiLlama USD reference observations when there is none. Stock, index, commodity and currency observations come from Yahoo Finance data endpoints. Current Binance USDT prices are converted to USD with a Coinbase Exchange USDT/USD observation whose source and time are shown. When no real USDT/USD history exists, the history is presented explicitly as a model assuming 1 USDT = 1 USD; USDT is not a dollar guarantee. Currency rates rely on Yahoo Finance observations, with ExchangeRate-API daily data as the fallback source; they are not bank buy/sell rates. Each product is shown in the currency it trades in and at the source’s own price: Borsa Istanbul stocks in Turkish lira, German and French stocks in euros, US stocks and crypto in US dollars. A value in another currency appears only when you choose it on the product page, converted once and marked as approximate. Currency pairs are quotation rates, indices are points and bonds are yield percentages.
BIST data is treated as delayed by at least 15 minutes; the data provider’s timestamp is used. PAXG-based gold models do not represent Grand Bazaar buy/sell prices. Unverified volume and historical metrics are hidden.
DefiLlama reference prices are taken with checks on source identity, symbol, confidence score and time; OHLC candles or trading volume are not generated when they are missing. For eligible pairs without direct currency history, the series calculated from sourced USD cross-rate closes is labelled as a model. Yahoo USX/USc cent and GBp/GBX penny units are converted by their explicit currency codes.
Market sentiment
The daily Bitcoin Fear & Greed Index from Alternative.me is used. The score and past observations come from the source; it does not represent BIST or all global markets. During a source outage the last received score and its date are kept.
Calculations
The compound return and position tools are scenarios based on your assumptions. The regular investing and comparison tools produce no result without a real historical series. Gold models are calculated from the source price, weight and purity; they are not jeweller buy/sell quotations. Historical currency conversion uses the period’s closing rate; a converted candle is not claimed to be the real intraday trading range. Reserve visuals are historical data sets for their own reference period.
