Exit logic comparisons

Freqtrade allows your strategy to implement different exit logics. This section aims to compare each different section, helping you to choose the one that best fits your needs.

• populate_exit_trend() - Vectorized exit logic based on the dataframe
  ✅ Use to define exit conditions based on indicators or other data that can be calculated in a vectorized manner.
  🚫 Don't use to customize exit conditions for each individual trade, or if trade data is necessary to make an exit decision.
• custom_exit() - Custom exit signal, called for every open trade every iteration until a trade is closed.
  ✅ Use to customize exit conditions for each individual trade, or if trade data is necessary to make an exit decision.
• custom_stoploss() - Custom stoploss, called for every open trade every iteration until a trade is closed. The value returned here is also used for stoploss on exchange.
  ✅ Use to customize the stoploss logic to set a dynamic stoploss based on trade data or other conditions.
  🚫 Don't use to exit a trade immediately based on a specific condition. Use custom_exit() for that purpose.
• custom_roi() - Custom ROI, called for every open trade every iteration until a trade is closed.
  ✅ Use to customize the minimum ROI threshold to exit a trade dynamically based on profit or other conditions.
  🚫 Don't use to exit a trade immediately based on a specific condition. Use custom_exit() for that purpose.
  🚫 Don't use for static roi. Use minimal_roi for that purpose instead.
