🧪 Examples

Strategy Evaluation with Metrics

from xnoapi.vn.metrics import Metrics, Backtest_Derivates
from xnoapi.vn.data import derivatives
import numpy as np

# Generate signal: simple strategy based on 20-period median
def gen_position(df):
    return df.assign(
        position=np.sign(df["Close"] - df["Close"].rolling(20).median())
    )

# Fetch 1-minute historical data
df = derivatives.get_hist("VN30F1M", "1m")
df_pos = gen_position(df)

# Backtest the strategy
backtest = Backtest_Derivates(df_pos, pnl_type="raw")

# Initialize metrics
metrics = Metrics(backtest)

# === Backtest_Derivates Methods ===

# Cumulative PNL
cumulative_pnl = backtest.PNL()

# Daily cumulative PNL
daily_cumulative_pnl = backtest.daily_PNL()

# Estimate Minimum Capital Required
min_capital = backtest.estimate_minimum_capital()

# PNL Percentage
pnl_percentage = backtest.PNL_percentage()

# === Metrics Methods ===

# Average Loss
metrics.avg_loss()

# Average Return
metrics.avg_return()

# Average Win
metrics.avg_win()

# Max Drawdown
metrics.max_drawdown()

# Win Rate
metrics.win_rate()

# Volatility
