Key takeaways
- Consequent encroachment (CE) is the 50% level of a fair value gap, and the term is also used for the midpoint of a long wick.
- Mean threshold is the 50% level of an order block, most often measured on the candle's body.
- Both are simple midpoints: (top + bottom) ÷ 2.
- Traders watch for reactions at these lines and often treat a candle body closing beyond them as a sign of weakness.
- A 50% level is a reference, not a precise turning point; plan stops beyond the zone, not on the line.

Many ICT tools are zones, and a zone raises an obvious question: where inside it should you pay attention? ICT answers with a simple idea that appears again and again in the framework, the 50% level. For a fair value gap it is called consequent encroachment (CE). For an order block it is called the mean threshold.
This lesson shows how to draw both, how they work together, and how to use them for entries and invalidation without treating them as magic lines.
What it is
Both terms describe the midpoint of a zone:
Midpoint = (top of zone + bottom of zone) ÷ 2
- Consequent encroachment (CE): the 50% level of a fair value gap. For a bullish FVG, it is halfway between candle 1's high and candle 3's low. The term is also used for the midpoint of a long wick, which is relevant when you study rejection blocks.
- Mean threshold (MT): the 50% level of an order block. Most ICT traders measure it on the candle's body (open to close). Some measure the full high-to-low range instead. Both conventions exist, so pick one and use it consistently.
The reasoning traders give is that a zone holding above (or below) its midpoint shows the original move is still being defended. If price trades through the midpoint and candle bodies close beyond it, the zone has been "accepted" more deeply than a healthy retest would suggest. This is a framework for reading charts, not a measured law of order flow.
| Tool | Zone | 50% level is called | Typical use |
|---|---|---|---|
| Fair value gap | Candle 1 wick to candle 3 wick | Consequent encroachment | Entry or invalidation line |
| Long wick | Body extreme to wick extreme | Consequent encroachment of the wick | Reaction level |
| Order block | Body (or full range) of the candle | Mean threshold | Invalidation line, entry |
How to identify it
- Mark the zone correctly first. Use wicks for an FVG and the body (or range, by your rule) for an order block.
- Calculate the midpoint. Add the top and bottom and divide by two. Most platforms let you draw a 50% line inside a rectangle.
- Label the line. Write "CE" or "MT" so you know which zone it belongs to when zones overlap.
- Choose your rule for a break. Decide whether a wick through the line is acceptable and whether a body close beyond it ends the idea.
- Check the timeframe. Judge closes on the timeframe where the zone was drawn. A 1-minute close beyond a 1-hour CE carries less weight.
Worked example: CE and mean threshold on GBP/USD
All prices are illustrative. GBP/USD is quoted to four decimals, and one pip is 0.0001.
On the 15-minute chart, GBP/USD pulls back to a low. The last down-close candle before a sharp rally opens at 1.2708, has a high of 1.2711 and a low of 1.2690, and closes at 1.2696. That candle becomes a bullish order block when the next candles rally through a swing high at 1.2735 and reach 1.2752.
The rally also leaves a bullish FVG. The order block candle is candle 1 of the pattern, with a high of 1.2711, and candle 3 has a low of 1.2725.
| Level | Price |
|---|---|
| FVG top (candle 3 low) | 1.2725 |
| FVG consequent encroachment | 1.2718 |
| FVG bottom (candle 1 high) | 1.2711 |
| Order block open (body top) | 1.2708 |
| Order block mean threshold | 1.2702 |
| Order block close (body bottom) | 1.2696 |
| Order block low | 1.2690 |
CE: (1.2725 + 1.2711) ÷ 2 = 1.2718. Mean threshold: (1.2708 + 1.2696) ÷ 2 = 1.2702.
The two 50% lines give the trader a ladder of evidence:
- Price holds above CE (1.2718): the gap is respected and the move looks strong.
- A body closes below CE but above the mean threshold: the gap is weakening, but the order block below may still hold.
- A body closes below the mean threshold (1.2702): the bullish idea is considered failed.
A trader might place a buy limit at the CE, 1.2718, with a stop-loss at 1.2698, four pips below the mean threshold. That is 20 pips of risk. A target at buy-side liquidity above the old highs, say 1.2778, is 60 pips away, a 1:3 risk-to-reward ratio.
With a $10,000 account risking 1% ($100), and about $10 per pip per standard lot on GBP/USD, size = $100 ÷ (20 × $10) = 0.5 lots. Use the Position Size Calculator to confirm.
Note the stop sits beyond the mean threshold, not on it. A line that many traders watch is also a line that price often tests with a wick.
How traders use it
- Entry refinement. Instead of entering at the edge of a gap, some traders wait for price to reach CE, which improves the risk-to-reward ratio but means some trades are missed.
- Invalidation. A body close beyond CE or the mean threshold is a common reason to exit early, keeping losses smaller than a full stop.
- Reading strength. Gaps that are only tapped at the edge suggest urgency; gaps traded to CE and beyond suggest a slower, weaker market.
- Stacking zones. When an FVG sits directly on top of an order block, as above, the two midpoints give layered levels for entries and exits.
- Spotting failures. A gap that closes through its CE and then fully through its far edge may later act as an inverse FVG.
Common mistakes
- Drawing the zone wrong. A midpoint of a badly drawn zone is meaningless. Get wicks and bodies right first.
- Treating 50% as exact. Price often overshoots or falls short by a pip or two. Use the line as a reference.
- Stops on the line. Placing a stop exactly at CE or the mean threshold invites being tagged by a wick.
- Mixing conventions. Measuring the mean threshold on the body one day and the range the next makes your records useless.
- Ignoring context. A CE that holds in a strong opposing higher-timeframe trend is still a low-quality trade.
Summary
Consequent encroachment is the 50% level of a fair value gap or a long wick, and the mean threshold is the 50% level of an order block, usually measured on the body. Both are simple midpoints that help traders choose entries inside a zone and decide when a zone has failed, typically on a candle body close beyond the line. They are references rather than guarantees, so keep stops beyond the zone and size every position so a loss is affordable.
