# 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.
