+### Profit ratio for short trades
+
+`profit_ratio = (1 - (close_trade_value/self.open_trade_value))`
+
+### Profit ratio for leveraged trades
+
+`leveraged_profit_ratio = profit_ratio * leverage`
+
+## Tests
+
+To add shorting and leverage functionality to freqtrade, the majority of changes involved editing existing methods within `freqtrade/persistence/models.py`. `freqtrade/persistence/models` was already fully tested, so to test the new functionality, new tests were created inside `tests/persistence/test_persistence_short.py` and `tests/persistence/test_persistence_leverage.py`, which mirrored the the tests inside `tests/persistence/test_persistence.py`, but accounted for additional factors created by _leverage_ and _short trading_
+
+### Factors added to freqtrade/persistence
+
+#### Short trading
+
+- Exit trade amounts are slightly higher than their enter amounts, due to the extra amount purchased for paying back interest owed for the amount of currency borrowed
+- Profit calculation were calculated inversely compared to longs
+- Stoplosses moved in the reverse direction
+- The entering/starting trade was a "sell" and the exiting/closing trade was a "buy"
+
+#### Leveraged long trading
+
+- Leveraged long trades had the amount of interest owed subtracted from the value of their exiting trade
+
+<hr>
+
+These are all the tests from `test_persistence.py` for which mirror versions were created inside `test_persistence_short.py` and `test_persistence_long.py`. These tests were chosen because the factors listed above affect the output of these methods. Some tests were only mirrored within `test_persistence_short.py` because the methods they test would not be impacted by leverage. `test_persistence_short.py`repeated tests from `test_persistence.py`, but for short trades, to make sure that the methods tested calculated the right values for shorts, and `test_persistence_long.py`repeated tests from `test_persistence.py`, but for leveraged long trades, to make sure that the methods tested calculated the right values when leverage was involved

+
+- `LocalTrade.stop_loss` is never lower than `LocalTrade.liquidation_price` for longs
+- `LocalTrade.stop_loss` is never higher than `LocalTrade.liquidation_price` for shorts
+- `LocalTrade.stop_loss` and `LocalTrade.intial_stop_loss` are assigned to the value of `LocalTrade.liquidation_price` when no `LocalTrade.stop_loss` is not assigned

+- `test_interest_binance_short`

+- `test_interest_binance_lev`

+- correct interest calculated for a long trade made on kraken
+- correct interest calculated for a short trade made on binance
+- correct interest calculated for a long trade made on binance

+- test_update_with_binance_lev
+
+Conditions tested for
+
+- borrowed was equal to `amount` for short trades
+- borrowed was equal to `amount * leverage-1` for long trades (1 is subtracted from leverage because the collateral is in the borrowed currency and is already owned)
