title: How to get ALL (or multiple) pair's historical klines from Binance API in ONE request?
body: <p>I have a trading bot that trades multiple pairs (30-40). It uses the previous 5m candle for the price input. Therefore, I get 5m history for ALL pairs one by one. Currently, the full cycle takes about 10 minutes, so the 5m candles get updated once in 10m, which is no good.</p>
  <p>Any ideas on how to speed things up?</p>
