Checklist institusi sebelum entry gap
Gap besar di pre-market bukan sinyal entry otomatis. Itu bait buat retail.
Gap 3% di pre-market dengan volume 40K shares ≠ gap 3% di session reguler dengan volume 2M shares.
Institusi bisa manipulate price dengan order kecil kalau likuiditas rendah.
Gap harus >1.5x Average True Range 14-day
Cara cek:
1. ATR(14) di TradingView = $6.80
2. Gap size = $12.50
3. Ratio = 12.50 / 6.80 = 1.84x → Valid
→ Kalau gap <1.5x ATR = noise, bukan signal
Minimum 30% dari average daily volume
Kalau ADV stock lo 5M shares, pre-market volume harus >1.5M buat gap dianggap liquid.
→ High pre-market volume = institutional interest
Gap tanpa catalyst = suspect
Valid catalyst: earnings beat, M&A rumor, analyst upgrade, FDA approval, partnership announcement.
Red flag: Gap besar tanpa headline news apapun = insider positioning atau manipulation.
First 30 menit = volatility trap. Market maker test level atas-bawah untuk cari liquidity.
Timing ideal:
1. Wait sampai 10:00 AM
2. Lihat gap hold atau fade
3. Entry kalau gap hold + volume confirm
→ Patience > FOMO
Gap >2% yang fade within first hour kalau pre-market volume <30% ADV
Study: 2023 gap-up days, NASDAQ 100 stocks (n=840+ events)
