+# to delay each request by waiting for some time to stay below request rate limits
+
+exchange = ccxt.bitfinex()
+
+# the rateLimit is in milliseconds → divide it by a thousand to get seconds
+delay = exchange.rateLimit / 1000

+    # this can be any call instead of fetch_ticker, really
+    print(exchange.fetch_ticker('BTC/USD'))
+    time.sleep(delay)  # sleep a little before sending each next request
