#
# Run at your own risk.
# I don't know what I'm doing.
# Backtests quite a bit better than it actually works.
# Let me know if you manage to improve it!
#
# Buys when RSI crosses the low threshold
# Doesn't wait for reversal, trying to anticipate the "bottom" of the dip.
#
# Sells on ROI (often), Stoploss (sometimes), or RSI high (rarely)
#
# Custom Stoploss starts wide and then narrows over time
# Combined with ROI, every trade will be forced to close in custom_stop_ramp_minutes, win or lose
#
# Bull/Bear trends
#
# Uses two different sets of entry/exit thresholds, which are used depending on the longer RSI trend
# Enter earlier and leave later when bullish; enter later and leave earlier when bearish
#
# Strengths
#
# Choppy markets - requires strong enough dips to trigger a entry, then we want a bounce back up
#
# Weaknesses
#
# Steady bull runs - no dips to entry, missed opportunity
# Sudden ongoing bear runs - if the market keeps dipping and dropping repeatedly that's bad,
# so use protections, eg.
#
# "protections": [

#         "stop_duration": 720,
#         "only_per_pair": true
#     },
# ],  
# 
# Works best on high volume pairs with decent volatility eg.
#
# "SXP/USD",
# "MATIC/USD",
# "SUSHI/USD",
# "CHZ/USD",
#
# and not ETH/USD or BTC/USD
