Getting Started with Alpaca

Hi :slight_smile: new here on the forum and to alpaca. so I followed this guide on getting started : Coding a Cryptocurrency Trading Bot With Alpaca in Python
In this they use this line:
bars = api.get_crypto_bars(“BTCUSD”, TimeFrame.Minute).df
I would like to get the price every 5 seconds how do I do that?
is minute the lowest timeframe? I tried
bars = api.get_crypto_bars(“BTCUSD”, TimeFrame.Seconds).df
any ideas?
