NFI_UO Strategy: In-Depth Analysis

Strategy ID: #242 (Strategy #242 of 465) Strategy Type: NFI Series - Ultimate Oscillator Mode Timeframe: 15 Minutes (15m)

---

I. Strategy Overview

NFI_UO is a strategy variant within the NFI (Nostalgia For Infinity) series that specifically uses the Ultimate Oscillator (UO). The Ultimate Oscillator, developed by Larry Williams in 1985, is a multi-period momentum indicator that reduces false signals by synthesizing data from multiple timeframes.

The "UO" in the strategy name directly points to the Ultimate Oscillator indicator, meaning this strategy uses UO as its core analytical tool, combined with NFI's multi-condition architecture to achieve more reliable trade signal filtering.

II. Strategy Configuration Analysis

2.1 Core Risk Parameters

# ROI Exit Table (Time: Minimum Profit Rate)
minimal_roi = {
    "0": 0.13,    # Immediate exit: 13% profit
    "30": 0.09,   # After 30 minutes: 9% profit
    "60": 0.05,   # After 60 minutes: 5% profit
    "120": 0.02   # After 120 minutes: 2% profit
}

# Stop-Loss Settings
stoploss = -0.11  # -11% hard stop-loss

# Trailing Stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.045   # 4.5% trailing activation point
trailing_stop_positive_offset = 0.075  # 7.5% offset trigger

Design Philosophy:

• Higher Initial ROI (13%): Expects to capture larger price movements
• Moderate Stop-Loss (-11%): Between conservative and aggressive
• Trailing Stop: 4.5% activation, 7.5% offset, suitable for trending markets
