How is the pure gold value calculated?
A quarter gold coin weighs 1.7539 g gross at 22 carat (916/1000 fineness), so the gold it contains is worth:
6,679.93 ₺ × 1.7539 × 0.916 = 10,731.80 ₺
This is the pure gold value, not a jeweller's selling price: craftsmanship and margin are added on top of it.

RSI (14): 49.8. Above 70 counts as overbought and below 30 as oversold territory; on its own it does not give a direction.
A price above its moving averages shows that the recent period has been spent in an uptrend. This is a measure of state, not a buy or sell signal.

Data and method
Prices come from public market data (Yahoo Finance) and are delayed by roughly 15 minutes; they are not live trade prices. Changes are measured over calendar days (1 week = 7, 1 month = 30, 3 months = 91, 1 year = 365 days) against the earlier close of the same series, and are computed on this page. Annualised volatility is the standard deviation of the last year's daily returns, annualised (√252; √365 for crypto, which trades around the clock). Largest drawdown is the deepest fall from a peak seen in the last year. Correlation with BIST 100 is measured on daily returns, not on prices — measured on prices, any two rising series always look highly correlated. Detail: data and method.
