title: What are the symbols used in Binance's dapi (coin futures api)?
body: <p>I am trying to download historical price data of BTC/USD perpetual futures using binance's api for coin futures, specifically, I'd like to use <a href="https://binance-docs.github.io/apidocs/delivery/en/#kline-candlestick-data" rel="noreferrer">this endpoint</a>. However, I cannot find what 'symbol' I have to specify for BTC/USD. I've tried multiple variations to no avail (such as BTCUSD, BTCUSD_perpetual, etc. I constantly get the error: &quot;Invalid symbol.&quot;</p>
