Afaik it should return -0.07 for 7% instead of -0.7.
As a side note, really interesting would also be an example for greater than 100% profits. especially when trailing stoploss, like
* Once profit is > 200% - stoploss will be set to 150%.
I assume it could be as simple as
```py
if current_profit > 2:
return (-1.50 + current_profit)
````
to achieve it
But I'm not quite confident, if the bot can handle stuff smaller than `-1`, since `1` and `-1` seem to have some special meaning and are often used to disable stoploss etc.
