Warning:
This is still work in progress, so there is no warranty that everything works as intended,

"""
class StackingDemo(IStrategy):
"""
This is the default strategy template with added functions for trade stacking / buying the same positions multiple times.
It should function like this:
Find good buys using indicators.
When a new buy occurs the strategy will enable rebuys of the pair like this:
self.custom_info[metadata["pair"]]["rebuy"] = 1
Then, if the price should drop after the last buy within the timerange of rebuy_time_limit_hours,
the same pair will be purchased again. This is intended to help with reducing possible losses.
If the price only goes up after the first buy, the strategy won't buy this pair again, and after the time limit is over,
look for other pairs to buy.
For selling there is this flag:
self.custom_info[metadata["pair"]]["resell"] = 1
which should simply sell all trades of this pair until none are left.
You can set how many pairs you want to trade and how many trades you want to allow for a pair,
but you must make sure to set max_open_trades to the produce of max_open_pairs and max_open_trades in your configuration file.
Also allow_position_stacking has to be set to true in the configuration file.
For backtesting make sure to provide --enable-position-stacking as an argument in the command line.
Backtesting will be slow.
Hyperopt was not tested.
