NostalgiaForInfinityV2 Strategy: In-Depth Analysis

Strategy ID: #250 (Strategy #250 of 465) Strategy Type: NFI Series - V2 Advanced Optimized Version Timeframe: 15 Minutes (15m) + 1 Hour Information Framework

---

I. Strategy Overview

NostalgiaForInfinityV2 (abbreviated NFI V2) is the second official optimized version of NostalgiaForInfinity (original). As the advanced version of the NFI V series, V2 performed parameter optimizations and strategy adjustments based on V1, representing a transition from "conservative approach" to "progressive approach."

V2 is characterized by "steady progress" — while retaining V1's core architecture, it moderately increased profit targets and tightened stop-loss controls, making the strategy more aggressive. Compared to V1, V2 is more suitable for investors with some risk tolerance pursuing higher returns.

Entry Conditions	Multiple optimized signals covering trend confirmation, support rebounds, divergence reversals
Exit Conditions	Multi-layer dynamic take-profit + stricter stop-loss protection + more aggressive trailing stop
Protection Mechanisms	EMA/SMA trend protection + volatility control + multi-period verification (V2 optimized)
Timeframe	15-minute primary framework + 1-hour information framework
Dependencies	pandas, numpy, TA-Lib, technical

II. Strategy Configuration Analysis

2.1 Core Risk Parameters

# ROI Exit Table
minimal_roi = {
    "0": 0.11,    # Immediate exit: 11% profit
    "30": 0.065,  # After 30 minutes: 6.5% profit
    "60": 0.035,  # After 60 minutes: 3.5% profit
    "120": 0.015  # After 120 minutes: 1.5% profit
}

# Stop-Loss Settings
stoploss = -0.095  # -9.5% hard stop-loss (stricter than V1)

# Trailing Stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.035      # 3.5% trailing activation point
trailing_stop_positive_offset = 0.055  # 5.5% offset trigger

Design Philosophy:

• Four-Tier ROI Target: 11% → 6.5% → 3.5% → 1.5%, more aggressive than V1
• Stricter Stop-Loss: -9.5% is 0.5% tighter than V1's -10%, stricter risk control
• More Aggressive Trailing: 3.5% activation, 5.5% offset, locks profits earlier than V1

IV. Exit Logic Details

4.1 Multi-Layer Take-Profit System (V2 More Aggressive)

V2 uses a four-tier progressive take-profit mechanism, more aggressive than V1:

Profit Rate Zone     Threshold       V1 Comparison    Signal Name
─────────────────────────────────────────────────────────────────────
0-30 minutes         11%             +1%              Quick Profit (more aggressive)
30-60 minutes         6.5%            +0.5%            Medium-term Target (raised)
60-120 minutes        3.5%            +0.5%            Conservative Exit (raised)
120+ minutes          1.5%            unchanged        End-of-Session Breakeven

V2 Take-Profit Design Philosophy:

• Initial target raised by 1%, capturing quick profit opportunities
• Secondary and tertiary targets simultaneously raised, not missing medium-term profits
• Quaternary target maintained at 1.5%, ensuring end-of-session breakeven

4.2 Special Exit Scenarios

Scenario	Trigger Condition	Signal Name	V2 Feature
Death Cross	Short-term MA crosses below long-term MA	Trend Exit	More sensitive death cross judgment
RSI Overbought	RSI exceeds specific threshold	Momentum Exit	Adjusted overbought threshold
Bollinger Upper Band	Price touches upper band	Resistance Exit	Combined with trailing take-profit
Trailing Stop Triggered	Profit retraces beyond threshold	Lock profits	Earlier activation (3.5%)
