I. Strategy Overview

NostalgiaForInfinityNextGen_TSL (abbreviated NFI NextGen TSL) is the "Trailing Stop Enhanced Version" of NostalgiaForInfinityNextGen. Building on NextGen's core multi-condition architecture, the TSL version comprehensively enhances the trailing stop mechanism, aiming to better protect profits and reduce drawdowns.

"TSL" stands for Trailing Stop Loss (追踪止损), which is this strategy's core differentiating feature. Compared to the original NextGen, the TSL version is more aggressive in profit protection, suited for traders pursuing steady profitability and drawdown control.

II. Strategy Configuration Analysis

2.1 Basic Risk Parameters

# ROI Exit Table (time: minimum profit rate)
minimal_roi = {
    "0": 0.10,    # Immediate exit: 10% profit
    "30": 0.05,   # After 30 minutes: 5% profit
    "60": 0.02,   # After 60 minutes: 2% profit
}

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

# Trailing Stop (TSL version core parameter - Enhanced)
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.015   # 1.5% trailing activation point (original 1%)
trailing_stop_positive_offset = 0.025  # 2.5% offset trigger (original 3%)
trailing_stop_negative = -0.02   # -2% negative trailing threshold (new)

Design Philosophy:

• Uses a time-decaying ROI strategy
• Enhanced Trailing Stop: TSL version raises trailing activation from 1% to 1.5%, lowers offset trigger from 3% to 2.5%
• Adds trailing_stop_negative parameter, more sensitive negative trailing
• Trailing stop activates earlier, locks in profits faster
• Hard stop-loss at -10% controls maximum loss per trade

2.2 TSL Parameter Comparison vs. NextGen Original

Parameter	NextGen Original	TSL Enhanced	Change Description
trailing_stop_positive	0.01 (1%)	0.015 (1.5%)	Trailing activation raised
trailing_stop_positive_offset	0.03 (3%)	0.025 (2.5%)	Offset trigger lowered
trailing_stop_negative	None	-0.02 (-2%)	Negative trailing added

Change Interpretation:

• Trailing Activation Raised: From 1% to 1.5%, meaning trailing starts when profit reaches 1.5%
• Offset Trigger Lowered: From 3% to 2.5%, enters trailing state earlier
• Negative Trailing Added: Allows triggering trailing stop when profit drawdown reaches 2%

Each entry condition has an independent protection parameter set:

Protection Type	Parameter Description	Options

Trend Following Group	4-6	EMA trend + momentum confirmation
Relaxed Entry Group	7-9	Fewer protection conditions
1h Confirmation Group	10-12	High-period trend verification
Aggressive Entry Group	13-14	Fast signal response
BTC Correlation Group	15-16	BTC trend filtering

IV. Exit Logic Details

4.1 Multi-Layer Take-Profit System

Profit Range          Threshold        Exit Strategy
───────────────────────────────────────────────────────
> 10%              Immediate        ROI initial exit
5%-10%             30 minutes       ROI secondary exit
2%-5%              60 minutes       ROI tertiary exit
< 2%               Hold             Wait for signal or stop-loss

4.2 Trailing Stop Mechanism (TSL Version Core)

TSL version's trailing stop mechanism is the core differentiating feature:

Trailing activation condition: profit >= 1.5%
Trailing trigger condition: profit >= 2.5% after which trailing begins
Trailing stop trigger: profit drawdown triggers trailing
Negative trailing threshold: profit drawdown >= 2%

Trailing Stop Flow:

1. When profit reaches 2.5%, trailing stop activates
2. Price continues rising, stop-loss line follows upward
3. Price pulls back, stop-loss line remains stationary
4. Profit drawdown reaches threshold, trigger stop-loss sell

TSL Version Advantages:

• Trailing activates earlier (1.5% vs 1%)
• Enters trailing state earlier (2.5% vs 3%)
• Negative trailing protection (-2% threshold)
• More aggressive profit protection

4.3 Special Exit Scenarios

Scenario	Trigger Condition	Signal Name
BB Upper Band Breakout	Continuous upper band breakout	Overbought exit
RSI Extreme	RSI overbought threshold	Momentum exit
Below EMA	Price breaks below EMA200	Trend exit
Trailing Stop	Profit drawdown triggers	Protection exit (TSL enhanced)

V. Risk Management Features

5.1 Enhanced Trailing Stop (TSL Core Feature)

TSL version's core advantage is trailing stop enhancement:

Negative Protection	-2% drawdown threshold	Prevents large profit drawdowns
Dynamic Adjustment	Stop-loss line follows upward	Locks in floating profit

5.2 Multi-Level Dip Protection (Safe Dips)
