## Market Price USD

> The price of certain symbol (e.g. gbtc) managed by each fund (e.g. Grayscale) reflects sentiment of investors in regulated markets. In this specific case, having single share of GBTC means having approximately 0.001 BTC invested to Grayscale. This endpoint returns metrics related to the US Dollar(USD) price of fund related stocks (e.g. gbtc). We provide five metrics, \`price\_usd\_open\`, USD opening price at the beginning of the window, \`price\_usd\_close\`, USD closing price at the end of the window, \`price\_usd\_high\`, the highest USD price in a given window, \`price\_usd\_low\`, the lowest USD price in a given window, and \`price\_usd\_adj\_close\`, USD adjusted closing price at the end of the window. All Symbol is not supported.

## Market Premium

> The premium of certain symbol (e.g. gbtc) is defined as (market price of the symbol - NAV) divided by NAV where NAV (Native Asset Value) is the current value of holdings (e.g. BTC price multiplied by BTC per Share). Higher the premium indicates market bullish, which also indicates downside risk. On the other hand, lower the premium indicates market bearish, which also indicates upside risk. All Symbol market premium is calculated by taking VWAP (Volume Weighted Average Ratio) of each fund data volume (usd).
