Basics

Starting freqtrade in dry-run or live mode (using freqtrade trade) will start the bot and start the bot iteration loop. This will also run the bot_start() callback.

By default, the bot loop runs every few seconds (internals.process_throttle_secs) and performs the following actions:

• Fetch open trades from persistence.
• Calculate current list of tradable pairs.
• Download OHLCV data for the pairlist including all informative pairs
  • This step is only executed once per Candle to avoid unnecessary network traffic.
• Call bot_loop_start() strategy callback.
• Analyze strategy per pair.
  • Call populate_indicators()
  • Call populate_entry_trend()
  • Call populate_exit_trend()
• Update trades open order state from exchange.
  • Call order_filled() strategy callback for filled orders.
  • Check timeouts for open orders.
    • Calls check_entry_timeout() strategy callback for open entry orders.
    • Calls check_exit_timeout() strategy callback for open exit orders.
    • Calls adjust_order_price() strategy callback for open orders.
      • Calls adjust_entry_price() strategy callback for open entry orders. only called when adjust_order_price() is not implemented
      • Calls adjust_exit_price() strategy callback for open exit orders. only called when adjust_order_price() is not implemented
• Verifies existing positions and eventually places exit orders.
  • Considers stoploss, ROI and exit-signal, custom_exit() and custom_stoploss().
  • Determine exit-price based on exit_pricing configuration setting or by using the custom_exit_price() callback.
  • Before an exit order is placed, confirm_trade_exit() strategy callback is called.
• Check position adjustments for open trades if enabled by calling adjust_trade_position() and place additional order if required.
• Check if trade-slots are still available (if max_open_trades is reached).
• Verifies entry signal trying to enter new positions.
  • Determine entry-price based on entry_pricing configuration setting, or by using the custom_entry_price() callback.
  • In Margin and Futures mode, leverage() strategy callback is called to determine the desired leverage.
  • Determine stake size by calling the custom_stake_amount() callback.
  • Before an entry order is placed, confirm_trade_entry() strategy callback is called.

This loop will be repeated again and again until the bot is stopped.
