IPDA 20-Day High / Low
Rolling 20-session swing extremes function as macro liquidity targets — the longer-horizon version of PDH/PDL. Slower but very reliable when price sits within reach.

The setup
IPDA (Interbank Price Delivery Algorithm) is ICT’s framing for longer-horizon liquidity. The rolling 20-day high and 20-day low are the most actionable IPDA levels — they accumulate enough resting orders to act as genuine draws.
Line ships on our chart HUD as 20D HIGH / 20D LOW.
Entry rules
- Window: rolling 20-session daily highs and lows, recomputed each session
- Proximity gate: fire only when distance <
8 × ATR14 - Direction: 20D HIGH = bull (rising to tag), 20D LOW = bear (falling to tag)
- Target: the exact 20D extreme
- TTL: week-long (multi-session)
Stats by distance
| Distance | n | Touch within 5 sessions |
|---|---|---|
| < 2 × ATR14 | 480 | 81% |
| 2–4 × ATR14 | 620 | 67% |
| 4–6 × ATR14 | 510 | 52% |
| 6–8 × ATR14 | 290 | 38% |
Closer = much more likely. The 8 × ATR14 cap is where the edge dies entirely.
Why Tier 2
The signal is reliable but the time-to-target is long — multiple sessions in many cases. Useful as a macro overlay to keep day-trade direction aligned with the bigger draw, but rarely the primary trigger by itself.
