""" E0V1E_Shorts Strategy A shorts-only variant of the E0V1E strategy, designed to profit in bear markets and during overbought conditions. This strategy mirrors the successful long-only approach but inverts the logic for short positions. Original E0V1E Strategy (Longs): - Uses EWO (Elliott Wave Oscillator) for momentum divergence - Simple RSI and EMA-based entries - Fast 5m timeframe Strategy Concept: Uses Elliott Wave Oscillator (EWO) to identify momentum divergence for short entries. EWO measures the percentage difference between fast and slow EMAs. Entry Conditions (OR logic - either triggers entry): 1. Short EWO: Price above EMA during uptrend (inverted from long logic) 2. Short Buy_1: RSI and SMA-based mean reversion shorts Exit Conditions: - Signal: Price falls below EMA - ROI: 7% initial target (more conservative than longs' 10%) - Stop Loss: -18.9% (tighter than longs due to short squeeze risk) - Custom Stoploss: Dynamic trailing Key Differences from Long Strategy: - Tighter stop loss: -18.9% vs -99% (shorts are riskier) - Lower ROI targets: 7% vs 10% (faster profit-taking) - Inverted entry/exit logic - Max 4 short positions: Position limit enforcement via confirm_trade_entry Author: Derived from E0V1E Version: 1.0.0 """ from datetime import datetime, timedelta import logging from typing import Optional, Union import freqtrade.vendor.qtpylib.indicators as qtpylib import talib.abstract as ta import pandas_ta as pta from freqtrade.persistence import Trade from freqtrade.strategy.interface import IStrategy from pandas import DataFrame from freqtrade.strategy import DecimalParameter, IntParameter from functools import reduce logger = logging.getLogger(__name__) def ewo(dataframe, ema_length=5, ema2_length=35): df = dataframe.copy() ema1 = ta.EMA(df, timeperiod=ema_length) ema2 = ta.EMA(df, timeperiod=ema2_length) emadif = (ema1 - ema2) / df['low'] * 100 return emadif class E0V1E_Shorts(IStrategy): """ Shorts-only Elliott Wave Oscillator strategy for bear markets.
