NFI_v5 Strategy Analysis

Strategy Number: #251 (251st of 465 strategies) Strategy Type: NFI Series Standard Version — Multi-Condition Trend Following Timeframe: 5 Minutes (5m) + 1 Hour Informational Timeframe

---

I. Strategy Overview

NFI_v5 is one of the standard versions of the NFI (Nostalgia For Infinity) series, continuously iterated by developer iterativ based on the classic Nostalgia strategy. As the fifth version of the NFI V series, v5 builds on the predecessor's multi-condition architecture with comprehensive parameter optimization and indicator refinement, representing the mature form of the NFI standard series.

The v5 version is positioned at the "balance point between stability and efficiency" — neither as conservative as early versions nor as complex as the ProAI series. Using the classic 5-minute timeframe, it integrates 20+ independent entry conditions with multi-tiered exit logic and comprehensive risk protection mechanisms. It is suitable for advanced traders pursuing stable returns.

Core Features

Feature	Description
Entry Conditions	20+ independent buy signals, each independently enableable/disableable
Exit Conditions	8 basic exit signals + multi-layer dynamic take-profit logic
Protection Mechanisms	20+ sets of entry protection parameters (EMA/SMA/safe dips/safe pumps)
Timeframe	5-minute primary timeframe + 1-hour informational timeframe
Dependencies	TA-Lib, technical, qtpylib, pandas, numpy

II. Strategy Configuration Analysis

2.1 Basic Risk Parameters

# ROI exit table (time: minimum profit rate)
minimal_roi = {
    "0": 0.08,    # Immediate exit: 8% profit
    "40": 0.05,   # After 40 minutes: 5% profit
    "80": 0.03,   # After 80 minutes: 3% profit
    "120": 0.01   # After 120 minutes: 1% profit
}

# Stop-loss settings
stoploss = -0.12  # -12% hard stop-loss

# Trailing stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.02    # 2% trailing activation point
trailing_stop_positive_offset = 0.035  # 3.5% offset trigger

Design Philosophy:

• Steady ROI ladder: First-tier ROI at 8%, slightly more conservative than the original Nostalgia (10%), suitable for stability-seeking traders
• Loose stop-loss buffer: -12% hard stop-loss gives the market sufficient volatility room, avoiding frequent stop-outs
• Gentle trailing stop: 2% activation, 3.5% lock-in, balancing profit protection and trend following

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 (20+ Sets)

Each entry condition has independent protection parameter sets, forming a multi-layered safety net:

Protection Type	Parameter Description	Function Description	Default Example
EMA Fast	Whether fast EMA is above EMA200	Trend confirmation	ema_fast_len=26
EMA Slow	Whether 1h slow EMA is above EMA200	Macro-cycle trend	ema_slow_len=100
Close Price Protection	Whether close price is above EMA	Price position confirmation	close_above_ema_fast_len=200
SMA200 Rising	Whether SMA200 is in uptrend	Long-term trend confirmation	sma200_rising_val=28
Safe Dips	Downward magnitude threshold protection	Prevents bottom-fishing at mid-slope	safe_dips_type=80
Safe Pumps	Upward magnitude threshold protection	Prevents chasing highs	safe_pump_type=70
BTC Trend	Whether BTC 1h is non-declining	Market correlation protection	btc_1h_not_downtrend

3.2 Typical Entry Condition Examples

Condition #1: RSI Oversold + MFI Low Value

# Logic
- RSI(1h) between 30-84 (macro-cycle not extreme)
- RSI(14) < 36 (oversold zone)
- MFI < 44 (low money flow)
- Price has minimum rise from 36-period low (excludes crash)

Condition #2: Bollinger Lower Band Breakout

# Logic
- RSI < RSI(1h) - 39 (relatively weak)
- MFI < 49 (low money flow)
- Close < Bollinger lower band × 0.983 (deep Bollinger break)

Condition #3: EMA Golden Cross + Bollinger Support

# Logic
- EMA26 > EMA12 (short-term golden cross)
- EMA difference > open price × coefficient (golden cross strength confirmation)
- Close < Bollinger lower band × offset coefficient (price position)

Condition #4: SMA Offset Strategy

# Logic
- Close < SMA × offset coefficient (price relative to moving average position)
- Volume confirmation
- RSI oversold confirmation

3.3 20+ Entry Conditions Classification

Condition Group	Condition Numbers	Core Logic	Applicable Scenario
Oversold Rebound	1, 7, 8, 18, 20	RSI/MFI low value + oversold signals	Oversold bounce

EMA Trend	5, 6, 7, 14, 15	EMA golden cross + price position	Trend confirmation
SMA Offset	9, 10, 11, 12, 13	Price below SMA by specific ratio	Mean reversion
EWO Momentum	12, 13, 16, 17	Elliott Wave Oscillator	Momentum confirmation
Special Conditions	19, 21, 22, 23	Composite indicator strategies	Comprehensive signals

IV. Exit Conditions Details

4.1 Multi-Layer Take-Profit System

The strategy uses a tiered take-profit mechanism, dynamically adjusting exit conditions based on profit rate:

Profit Rate Zone          RSI Threshold    Signal Name
────────────────────────────────────────────────────────
> 18%                    < 32           signal_profit_10
14%-18%                  < 40           signal_profit_9
10%-14%                  < 50           signal_profit_8
8%-10%                   < 52           signal_profit_7
6%-8%                    < 48           signal_profit_6
5%-6%                    < 42           signal_profit_5
4%-5%                    < 40           signal_profit_4
3%-4%                    < 38           signal_profit_3
2%-3%                    < 36           signal_profit_2
1%-2%                    < 34           signal_profit_1
< 1%                    < 32           signal_profit_0

Design Principles:

• Higher profit = lower RSI threshold (stricter exit conditions)
• Prevents greed, locks in profits promptly
• Dynamically adjusts based on market momentum

4.2 Special Exit Scenarios

Scenario	Trigger Condition	Signal Name	Description
Below EMA200 take-profit	Price < EMA200 + profit threshold met	signal_profit_u_*	Weak take-profit
Pump protection	24h/36h/48h rise detection + profit	signal_profit_p_*	Prevents high pullback
Declining trend	SMA200 declining + profit zone	signal_profit_d_*	Trend reversal protection
Trailing take-profit	Max profit drawdown + RSI zone	signal_profit_t_*	Dynamic profit locking
Holding duration	Held > 900 minutes + profit	signal_profit_l_1	Time stop
