Session Filter — Filter Sesi Perdagangan

File: src/session_filter.py Class: SessionFilter Zona Waktu: WIB (Waktu Indonesia Barat / GMT+7)

Apa Itu Session Filter?

Session Filter mengontrol kapan bot boleh trading berdasarkan sesi pasar global. Setiap sesi memiliki karakteristik volatilitas yang berbeda — bot memilih sesi terbaik untuk memaksimalkan peluang.

Konfigurasi Sesi (Terkini)

Sesi	Jam WIB	Volatilitas	Trading	Lot Multiplier	Catatan
Sydney	06:00 - 13:00	Low	Ya	0.5x	Backtest membuktikan profit $5.934
Tokyo	07:00 - 16:00	Medium	Ya	0.7x	Volume cukup
Tokyo-London Overlap	15:00 - 16:00	High	Tidak	0.0x	#24B: Backtest +$345 tanpa sesi ini
London	15:00 - 23:59	High	Ya	1.0x	Sesi utama Eropa

New York	20:00 - 23:59	Extreme	Ya	1.0x	Sesi utama AS
Off Hours	Lainnya	Low	Tidak	0.0x	Di luar semua sesi

Zona Bahaya

Zona	Jam WIB	Alasan	Aksi
Dead Zone	00:00 - 04:00	Likuiditas rendah, spread tinggi	Blokir trading
Rollover	04:00 - 06:00	Spread sangat lebar saat rollover	Blokir trading
Jumat Close	Sabtu 04:30+	Mendekati tutup weekend	*Blokir entry* baru**
Weekend	Sabtu - Minggu	Pasar tutup	Blokir sepenuhnya

Jam Skip Khusus (#34A)

Selain filter sesi, ada filter waktu tambahan dari optimasi backtest:

# main_live.py — Filter #34A
# Skip jam 9 dan 21 WIB — backtest menambah +$356 profit
wib_hour = datetime.now(ZoneInfo("Asia/Jakarta")).hour
if wib_hour in (9, 21):
    return  # Jam transisi — volatilitas tidak optimal

Cara Kerja

def can_trade(self) -> Tuple[bool, str, float]:
    """
    Returns:
        can_trade: Boleh trading atau tidak
        reason: Alasan dalam bahasa Indonesia
        multiplier: Pengali lot size (0.0 - 1.2)
    """
    # 1. Cek weekend
    if self.is_weekend():
        return False, "Market tutup (weekend)", 0.0

    # 2. Cek Friday close
    if self.is_friday_close():
        return False, "Mendekati penutupan Jumat", 0.0

    # 3. Cek zona bahaya
    if self.is_danger_zone():
        return False, "Zona bahaya: spread melebar", 0.0

    # 4. Cek sesi saat ini
    session, config = self.get_current_session()
    if not config.allow_trading:
        return False, f"Trading tidak diizinkan saat {config.name}", 0.0

    return True, f"Trading OK - {config.name}", config.position_size_multiplier

Pengaruh pada Position Sizing

Session multiplier langsung mengubah ukuran lot:

# main_live.py
safe_lot = smart_risk.calculate_lot_size(...)
safe_lot = max(0.01, safe_lot * session_multiplier)

# Contoh (akun $5.000):
# London-NY Overlap: 0.02 * 1.2 = 0.024 → 0.02 lot (setelah rounding)
# Sydney:           0.02 * 0.5 = 0.010 → 0.01 lot (half size)
# Tokyo:            0.02 * 0.7 = 0.014 → 0.01 lot

Waktu Berita Dampak Tinggi

Bot juga memiliki daftar waktu berita ekonomi penting:

Berita	Jam WIB	Buffer Sebelum	Buffer Setelah
NFP (Non-Farm Payrolls)	19:30	15 menit	30 menit
FOMC (Federal Reserve)	01:00	15 menit	45 menit
CPI (Consumer Price Index)	19:30	15 menit	30 menit

Catatan: News Agent saat ini nonaktif (main_live.py baris 64). Filter berita direncanakan untuk diaktifkan kembali di versi mendatang.
