II. Strategy Configuration Analysis

2.1 Basic Risk Parameters

# ROI Exit Table
minimal_roi = {
    "0": 0.18724,    # Immediate exit: 18.72% profit
    "20": 0.04751,   # After 20 minutes: 4.75% profit
    "30": 0.02393,   # After 30 minutes: 2.39% profit
    "72": 0          # After 72 minutes: break-even exit
}

# Stoploss Settings
stoploss = -0.28819  # -28.82% hard stoploss

# Dynamic ROI Configuration
use_dynamic_roi = True
droi_trend_type = 'any'           # Any of RMI/SSL/Candle trend
droi_pullback = False             # Whether pullback follows ROI table
droi_pullback_amount = 0.015     # Pullback threshold

2.2 Custom Stoploss Configuration

use_custom_stoploss = True
cstp_threshold = -0.05           # Activates when profit < -5%
cstp_bail_how = 'time'            # Time / ROC / any method
cstp_bail_time = 961              # Force exit after 961 minutes
cstp_bail_roc = -0.018            # Exit when ROC < -1.8%

III. Entry Conditions Details

3.1 Informational Layer Protection Mechanism

The strategy uses the 1-hour timeframe as an informational layer with two layers of protection:

# Upper boundary protection
if inf_guard == 'upper' or 'both':
    conditions.append(
        close <= 3d_low + inf_pct_adr_top * adr
    )

# Lower boundary protection
if inf_guard == 'lower' or 'both':
    conditions.append(
        close >= 3d_low + inf_pct_adr_bot * adr
    )

3.2 Core Buy Condition (BinHV45 Strategy)

# Bollinger Band breakout buy
conditions.append(
    bb_lowerband.shift() > 0 &                          # Previous candle has lower band
    bbdelta > close * bbdelta_close &                   # Bollinger band width sufficient
    closedelta > close * closedelta_close &             # Close price change sufficient
    tail < bbdelta * tail_bbdelta &                    # Lower wick short
    close < bb_lowerband.shift() &                     # Close price breaks below lower band
    close <= close.shift()                             # Close not above previous candle
)

IV. Exit Conditions Details

4.1 Dynamic ROI System

The strategy uses min_roi_reached_dynamic for dynamic take-profit:

Trend Type	Trigger Condition	ROI Value
RMI Trend	RMI rising count >= 3	100% (no exit)
SSL Trend	SSL channel upward	100% (no exit)
Candle Trend	3+ consecutive bullish candles	100% (no exit)

4.2 Custom Stoploss Logic

def custom_stoploss(...):
    if current_profit < cstp_threshold:     # Profit < -5%
        if cstp_bail_how == 'time':        # Time-based
            if trade_dur > cstp_bail_time: # Exceeds 961 minutes
                return 0.001               # Force exit
        if cstp_bail_how == 'roc':         # ROC-based
            if sroc <= cstp_bail_roc:      # ROC < -1.8%
                return 0.001

V. Technical Indicator System

5.1 Core Indicators

Category	Indicator	Parameters	Purpose
Volatility	Bollinger Bands	12 period, 2x std dev	Price boundaries
Momentum	RMI	24/21/8 periods	Momentum judgment
Trend	SSL-ATR	21 period	Trend direction
Volatility	ATR	24 period	Volatility
Momentum	SROC	21/13/21 periods	Rate of change

5.2 Custom Indicators

MA Streak: Number of consecutive bullish/bearish candles
Percent Change Channel (PCC): Percentage change channel
Momentum Pinball: ROC-based RSI

VI. Risk Management Features

6.1 Multi-Layer Protection Mechanism

Informational layer protection: 1-hour timeframe ADR protection
Dynamic ROI: Adjusts take-profit based on trend strength
Custom stoploss: Dual protection based on time and momentum
Generous hard stoploss: -28.82% allows ample volatility room

6.2 Trend Judgment

The strategy uses three trend judgment methods:

RMI momentum indicator
SSL channel direction
Candle consecutive rise/fall

VII. Strategy Pros & Cons

✅ Pros

Highly parameterized: Every parameter is optimizable
Dynamic take-profit: Adjusts exit strategy based on trend strength
Multi-layer protection: Informational layer + trend judgment + take-profit/stoploss
Rich indicators: Integration of more than ten technical indicators

⚠️ Cons

Extremely complex: Code exceeds 1000 lines
Many parameters: Prone to overfitting
High computational load: Demanding on hardware

VIII. Applicable Scenarios

Market Environment	Recommended Config	Notes
Trending markets	Enable dynamic ROI	Let profits run during trends
High volatility	Keep default	Generous stoploss suits high volatility
Oscillating market	Lower ROI thresholds	Reduce trend protection

IX. Applicable Market Environments in Detail

9.1 Core Strategy Logic

Bollinger Band breakout: Buy when price breaks below the lower band
Trend protection: Use RMI/SSL to judge trends
Dynamic exit: Let profits run when trend continues, exit promptly when trend reverses

9.2 Performance in Different Market Environments

Market Type	Rating	Analysis
📈 Trending up	★★★★★	Dynamic ROI lets profits run
🔄 Wide-range oscillation	★★★★☆	Bollinger band breakout effective in ranges
📉 One-way down	★★☆☆☆	Trend protection may fail
⚡️ Extreme consolidation	★★★☆☆	Complex calculation, mediocre effect

X. Important Notes: The Cost of Complexity

10.1 Learning Curve

The strategy code exceeds 1000 lines with extensive custom functions and complex logic. It is recommended to first understand the core indicator principles.

10.2 Hardware Requirements

The strategy has a massive computational load:

Number of Pairs	Min RAM	Recommended RAM
20-40 pairs	2GB	4GB
40-80 pairs	4GB	8GB

XI. Summary

Dyna_opti is a highly complex advanced strategy suitable for experienced quantitative traders. Its core value lies in:

Dynamic take-profit: Intelligently adjusts exits based on trend strength
Multi-layer protection: Informational layer + trend judgment + take-profit/stoploss
