Cryptocompare Api - 了解 API 返回值

我遇到了來自 cryptocompare.com 的 API，它從各種交易所獲取數據。

我不明白 API 呼叫返回的一些值

<https://min-api.cryptocompare.com/data/pricemultifull?fsyms=BTC&tsyms=INR&e=Unocoin>

問題

1. LASTVOLUME 和 LASTVOLUMETO 的區別
2. VOLUME24HOUR 和 VOLUME24HOURTO 的區別
3. TOTALVOLUME24H 和 TOTALVOLUME24HTO 的區別

VOLUME…TO 顯示以 INR 為單位的交易量，沒有 TO 則顯示以比特幣為單位的交易量。

由於一個比特幣約為 750 000 INR，過去 24 小時內由 75 個比特幣組成的數量相當於 61956574 INR 貨幣的數量。
