# Importing Candles

You need historical candles to run backtest simulations. The command to import candles is:

jesse import-candles exchange symbol start_date

A working example would be:

jesse import-candles 'Binance' 'BTCUSDT' '2018-06-01'

This will import candles for BTCUSDT from Binance since 2018-01-01 until this very moment.

TIP

You may run this command as many times as you desire. Duplicate candles will get skipped automatically.

That means in the future, you can run the same command you just used, for fetching most recent candles.
