Strategy 003: Oversold Long Entries with Multi-Indicator Filters

Article Strategy library · Author: freqtrade

Summary

Strategy 003 is a long-only cryptocurrency trading system on a five-minute timeframe. Its entry rule combines several oversold and trend conditions: low RSI and money flow, a strongly negative inverse Fisher transform of RSI, price below a simple moving average, and confirmation from either the longer exponential averages or a short EMA crossover. It also checks fast stochastic ordering. This stacks momentum, trend, and oscillator filters rather than relying on one indicator alone.

The exit signal occurs when Parabolic SAR is above price while the transformed RSI is positive. The configuration also defines a stepped return-on-investment schedule, a 10% stop loss, and no active trailing stop; settings may be overridden by external configuration. The document provides source logic but no market-specific test period or performance evidence. Because the entry requires many simultaneous conditions and the exit combines a separate trend signal with momentum, its behavior depends on indicator definitions, candle data, and execution assumptions. Backtesting and validation would be needed before drawing conclusions about profitability.

Key ideas

  • The strategy seeks long entries when several momentum and money-flow measures indicate oversold conditions.
  • It combines a price-versus-SMA condition with either longer-term EMA alignment or a short EMA crossover.
  • Fast stochastic values provide an additional entry filter.
  • The exit signal combines Parabolic SAR above price with a positive inverse Fisher RSI.
  • The configuration includes stepped ROI targets and a fixed stop loss, but no test results are supplied.
