ICT Macros Explained: The Algo's 20-Minute Windows

Kill zones tell you which hours institutions are active. Macros go one level deeper - they tell you the specific minutes inside those hours when price is most likely to move with purpose. If a kill zone is the meeting, a macro is the moment someone finally makes a decision.

This is where the ICT conversation moved in 2026. Instead of "trade the London open," the focus has shifted to the exact 20-minute pockets where the price delivery algorithm tends to expand and rebalance. Get the timing right and your setups line up with when the market actually delivers - not when it drifts.

What Are ICT Macros?

A macro is a fixed, recurring time window - typically around 20 minutes - during which price tends to move deliberately rather than randomly. The idea comes from ICT's core premise: price isn't pushed purely by retail supply and demand, it's delivered by an algorithm that seeks liquidity and rebalances inefficiencies on a schedule.

Macros are the timestamps on that schedule. Outside a macro, price often chops or consolidates. Inside a macro, it tends to:

• Run a nearby high or low to take liquidity
• Expand with displacement, leaving a fair value gap behind
• Deliver toward a clear draw on liquidity (an old high, low, or unfilled gap)

The distinction that trips people up: a macro is not a kill zone. Kill zones are multi-hour sessions (London open, New York open). Macros are the short windows nested inside those sessions. You can have several macros within a single kill zone.

What Are the ICT Macro Times?

Macros are referenced in New York local time (ET), which handles daylight saving automatically. These are the windows ICT traders most commonly track:

London macros

• 2:33 AM - 3:00 AM ET
• 4:03 AM - 4:30 AM ET

New York AM macros

• 8:50 AM - 9:10 AM ET (pre-open, around the equities open)
• 9:50 AM - 10:10 AM ET (the most-watched window)
• 10:50 AM - 11:10 AM ET

New York lunch macro

• 11:50 AM - 12:10 PM ET

New York PM macros

• 1:10 PM - 1:40 PM ET
• 3:15 PM - 3:45 PM ET (into the equities close)

You don't trade all of them. Most traders anchor to one or two - the 9:50-10:10 AM macro is popular because it sits right at the start of the Silver Bullet hour (10:00-11:00 AM ET) and often sets the tone for the rest of the AM session.

Why Do Macros Exist?

If you believe price is delivered algorithmically, then price has to do two jobs on repeat: seek liquidity (run stops clustered above highs and below lows) and rebalance inefficiency (return to unfilled fair value gaps). Macros are the recurring windows when the algorithm ramps up that activity.

That's why the behavior inside a macro is so consistent:

• Liquidity resting just outside the recent range gets taken first
• The real move only starts after that liquidity is collected
• The move targets the next obvious pool of liquidity

Whether or not you accept the full "algorithm" framing, the practical takeaway holds: certain minutes of the session carry far more directional intent than others, and trading them selectively beats trading the whole session indiscriminately.

What Happens Inside a Macro?

A clean macro usually delivers a three-part sequence. It's the same shape as the Judas swing, compressed into 20 minutes.

1. The sweep (first few minutes) - Price pushes against the intended direction to run stops. If the macro is going to deliver a move down, it often spikes up first to take buy-side liquidity. This is the trap that catches breakout traders.

2. Displacement - Price reverses hard in the intended direction with a strong, one-sided candle or two. This displacement leaves a fair value gap - the footprint of the algorithm moving with intent.

3. Delivery - Price works toward the draw on liquidity: the opposite side of the range, an old session high or low, or an unfilled gap. This is the part that actually pays.

Not every macro delivers this cleanly. Some are quiet. The skill is recognizing when the sequence is forming versus forcing a trade because the clock says a macro is open.

How Do You Trade an ICT Macro?

Step 1: Prepare before the window opens

• Mark the recent session high and low - these are the likely liquidity targets
• Know your higher-timeframe bias (are you looking for longs or shorts?)
• Note any unfilled fair value gaps price is approaching

Step 2: Wait for the sweep

• When the macro opens, let price run the obvious liquidity first
• Don't chase the initial push - that's usually the manipulation leg
• A clean sweep is a wick or brief push beyond a level, then rejection

Step 3: Enter on displacement + FVG

• Look for a sharp reversal that prints a fair value gap
• Enter on the retrace into that gap, not at the extreme
• Confirm with a lower-timeframe structure shift in your direction

Step 4: Manage toward the draw

• First target: the opposite side of the macro range or the swept level on the other side
• Trail as the 20-minute window closes - intent fades once the macro ends
• If the sequence doesn't form, stand aside. A macro is an opportunity, not an obligation.

How Do Macros Fit With Kill Zones and Quarterly Theory?

Macros are one layer in a nested time framework. It helps to see how they stack:

• Kill zones - the multi-hour sessions where institutions are active (London, New York)
• Macros - the ~20-minute windows inside those sessions where delivery concentrates
• Quarterly theory - the broader idea that time itself divides into accumulation, manipulation, and distribution quarters

The Silver Bullet model lives right at this intersection: a specific one-hour window (10:00-11:00 AM ET) that opens on the back of the 9:50 macro. Layering these gives you a reason to be at your screen at a specific minute - not just "sometime during New York."

What Common Macro Mistakes Should You Avoid?

1. Confusing macros with kill zones - Macros are the short windows inside the session, not the session itself. Trading the whole two-hour kill zone as if it were a macro defeats the point.

2. Entering on the sweep - The first push is usually the trap. Wait for displacement and a fair value gap before committing.

3. Forcing every window - Most macros don't produce a clean setup. Trading all eight in a day guarantees you take the messy ones.

4. Ignoring the timezone - Macro times are New York (ET). Convert them to your local time and be honest about which windows you can actually watch.

5. No liquidity target - A macro without a defined draw on liquidity is a guess. Always know what the move is reaching for before you enter.

How Do Macros Work With Indicators?

The tedious part of trading macros is marking session levels and watching the clock. Session-based tools like the Session Fib Fan can automate the reference points - plotting session highs and lows and previous-day levels - so when a macro opens you already know which liquidity pools are in play and where price is likely drawing toward. That leaves you free to watch the sweep-displacement-delivery sequence instead of redrawing levels every session.

What Are the Key Takeaways for ICT Macros?

• Macros are short, recurring ~20-minute windows inside a session when price delivery concentrates
• They sit inside kill zones - the session is the hour, the macro is the minute
• All macro times are referenced in New York time (ET)
• The 9:50-10:10 AM macro is the most-watched, opening the Silver Bullet hour
• Inside a macro, expect a sweep, then displacement with a fair value gap, then delivery to the draw
• Don't enter on the sweep and don't force every window - most macros stay quiet
• Always know which liquidity pool the move is reaching for before you trade
