title: How to make a binance futures order with ccxt in python?
body: <p>How can I place a market order in ccxt for binance futures?
  Trading on binance futures with ccxt is already implemented</p>
  
  <pre><code>https://github.com/ccxt/ccxt/pull/5907
  </code></pre>
  
  <p>In this post they suggest to use this line of code:</p>
  
  <pre><code>let binance_futures = new ccxt.binance({ options: { defaultMarket: 'futures' } })
  </code></pre>
  
  <p>The above line was written in JavaScript. How would the equivalent line in python look like?
  Like this I get an error:</p>
  
  <pre><code>binance_futures = ccxt.binance({ 'option': { defaultMarket: 'futures' } })
  NameError: name 'defaultMarket' is not defined
  </code></pre>
