NFI_v4_SMA Strategy: In-Depth Analysis

Strategy ID: #243 (Strategy #243 of 465) Strategy Type: NFI Series - v4 SMA Trend Mode Timeframe: 15 Minutes (15m)

---

I. Strategy Overview

NFI_v4_SMA is Version 4 (v4) of the NFI (Nostalgia For Infinity) series, using the classic SMA (Simple Moving Average) as its core trend identification tool. SMA is the oldest, most fundamental, and most classic indicator in technical analysis, smoothing price fluctuations by calculating the arithmetic mean of prices over a specific period to identify market trend direction.

The v4 version represents the NFI series' "return to classics" attempt at its mature stage. Compared to earlier versions' complex indicator combinations, v4_SMA returns to the most basic moving average analysis. While maintaining NFI's multi-condition architecture advantages, it significantly reduces strategy comprehension difficulty and computational complexity, making it especially suitable for traders pursuing simplicity and trend-following.

II. Strategy Configuration Analysis

2.1 Core Risk Parameters

# ROI Exit Table (Time: Minimum Profit Rate)
minimal_roi = {
    "0": 0.10,    # Immediate exit: 10% profit
    "30": 0.06,   # After 30 minutes: 6% profit
    "60": 0.04,   # After 60 minutes: 4% profit
    "120": 0.02   # After 120 minutes: 2% profit
}

# Stop-Loss Settings
stoploss = -0.10  # -10% hard stop-loss

# Trailing Stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.03    # 3% trailing activation point
trailing_stop_positive_offset = 0.05  # 5% offset trigger

Design Philosophy:

• Conservative ROI (10%): v4_SMA adopts a relatively conservative initial take-profit target, aligned with SMA signal's moderate sensitivity
• Standard Stop-Loss (-10%): Allows trend pullbacks while strictly controlling single-trade loss
• Conservative Trailing (3% activation / 5% offset): More conservative than other NFI variants, suitable for SMA signal's lagging nature

2.2 Order Type Configuration

order_types = {
    "entry": "limit",      # Limit order entry
    "exit": "limit",       # Limit order exit
    "stoploss": "limit",   # Limit stop-loss order
    "stoploss_on_exchange": False,
    "exit_timeout_count": 0,
}

III. Entry Conditions Details

3.1 Protection Mechanisms (Multiple Groups)

v4_SMA's protection mechanisms are built around SMA trend judgment:

Protection Type	Parameters	Function
Multi-Period Trend Filtering	SMA5/SMA20/SMA50 combination	Multi-period resonance confirms trend
Price Position Protection	Price relative to SMA position	Avoids chasing at highs
MA Slope Protection	SMA slope angle	Filters sideways consolidation
Volume Confirmation	Volume expansion verification	Confirms trend validity

3.2 Core Entry Condition Types

Condition Group 1: Golden Cross Signal

• Short-term SMA crosses above long-term SMA
• Price stands above all key MAs
• Volume expands with confirmation
• MA slope is upward

Condition Group 2: Pullback to MA Support

• Price pulls back to near SMA
• SMA slopes upward, showing uptrend
• Candlestick shows bounce-back pattern at MA
• Momentum indicators (RSI/AO) confirm

Condition Group 3: MA Multi-Asset Arrangement

• SMA5 > SMA20 > SMA50 in sequence
• Price trades above all MAs
• MA spacing is reasonable, trend is healthy
• Volume is stable

Condition Group 4: Breakout Confirmation Signal

• Price breaks above previous high
• SMA provides trend support
• Volume significantly expands
• Pullback does not break key MA

3.3 Entry Conditions Summary

Condition Group	Core Logic	Enabled Feature
Golden Cross	Short crosses above long	Trend initiation
Pullback Support	Price retraces to MA	Trend continuation
Multi-Asset Arrangement	MAs in sequence upward	Strong confirmation
Breakout Confirmation	Breakout + MA support	Trend strengthening

IV. Exit Logic Details

4.1 Multi-Layer Take-Profit System

v4_SMA employs a progressive take-profit strategy, gradually lowering targets as holding time increases:

Profit Rate Zone     Threshold       Signal Name
─────────────────────────────────────────────
0-30 minutes         10%             Quick Profit
30-60 minutes         6%            Medium-term Target
60-120 minutes        4%            Conservative Exit
120+ minutes          2%            End-of-Session Breakeven

4.2 Special Exit Scenarios

Scenario	Trigger Condition	Signal Name
Death Cross	Short-term SMA crosses below long-term SMA	Trend reversal exit
Price Breaks Below MA	Price breaks below key SMA	Support failure exit
MA Flattening	SMA slope approaches zero	Trend weakening exit
High-Altitude Divergence	Price diverges from RSI	Top signal exit

4.3 Basic Exit Signals (Examples)

1. Signal #1: SMA death cross forms → Sell

   • Short-term SMA crosses below long-term SMA
   • Trend may reverse

2. Signal #2: Price breaks below SMA support → Sell

   • Price breaks below key MA
   • Support becomes resistance

3. Signal #3: MA multi-asset arrangement breaks → Sell

   • MA crossovers become disordered
   • Trend structure damaged
