Strategy Migration between V2 and V3

We have put a great effort into keeping compatibility with existing strategies, so if you just want to continue using freqtrade in spot markets, there should be no changes necessary for now.

To support new markets and trade-types (namely short trades / trades with leverage), some things had to change in the interface. If you intend on using markets other than spot markets, please migrate your strategy to the new format.

Quick summary / checklist

  • Dataframe columns:
    • buy -> enter_long
    • sell -> exit_long
    • buy_tag -> enter_tag (used for both long and short trades)
    • New column enter_short and corresponding new column exit_short
  • trade-object now has the following new properties: is_short, enter_side, exit_side and trade_direction.
  • New side argument to callbacks without trade object
    • custom_stake_amount
    • confirm_trade_entry
  • Renamed trade.nr_of_successful_buys to trade.nr_of_successful_entries.
  • Introduced new leverage callback
  • @informative decorator now takes an optional candle_type argument
  • helper methods stoploss_from_open and stoploss_from_absolute now take is_short as additional argument.
  • INTERFACE_VERSION should be set to 3.
