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": 0.035,  # After 60 minutes: 3.5% profit
    "120": 0.015  # After 120 minutes: 1.5% profit
}

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

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

Design Philosophy:

• Moderate ROI (10%): Balances profit expectation with probability of achievement
• Standard Stop-Loss (-10%): Controllable loss baseline
• Flexible Trailing (3-5%): Protects existing profits

2.2 Order Type Configuration

order_types = {
    "entry": "limit",
    "exit": "limit",
