ICT Mean Threshold: Measuring an Order Block Body

A five-digit quote makes it easy to calculate a midpoint to half a pipette. It is much harder to decide which two prices belong in the calculation. A midpoint of the wick range is often several pips from the midpoint of the same candle’s body.

For an order-block study, decide what qualifies the source candle before discussing its mean threshold. Otherwise the precision of the number disguises uncertainty about the thing being measured.

Definition and chart context: order block body midpoint

Take a down-close candle with open 1.09364, close 1.09128, high 1.09407 and low 1.09069. Its body midpoint is 1.09246; its full-range midpoint is 1.09238. A later positive reaction at 1.09242 falls between the two. A chart labelled only fifty percent cannot tell a reviewer which measurement the setup actually tested.

For the ICT background, see Orderblocks. The worksheets below use stated study rules for measurement, confirmation and simulated fills. Those choices let you reproduce the examples; they are not claims that a public candle identifies the owner, size or intent of an institutional order.

Why this distinction matters

A midpoint gives two traders the same place to inspect how deeply price returned into a chosen block. A touch, a wick beyond, a close beyond and displacement through the far boundary are separate events. Keeping them separate allows you to investigate sensitivity to penetration without declaring every tiny overshoot a total invalidation or treating every midpoint as an automatic limit order.

How to identify it before the next candle

Save the source candle’s timeframe, timestamp, open, high, low and close. Verify its relation to the subsequent displacement through a previously identified swing. Mark the body midpoint as a line and keep the entire source candle visible. If your order-block definition uses several consecutive candles, state how the combined body boundary is calculated. Do not alternate between one candle and a cluster after the return.

First determine whether the candidate candle belongs to a qualified order block under the definition being studied. The midpoint calculation is deterministic for any candle, including a random one. It cannot supply the missing displacement, location or structural break that earned the block its status. Save that qualification beside the four raw prices.

Body midpoint, wick midpoint and the cost of one label

A down-close EUR/USD source candle opens at 1.08876, reaches 1.08913, trades as low as 1.08641 and closes at 1.08712. The body midpoint is 1.08794. The full-wick midpoint is 1.08777. A retracement to 1.08785 passed the body midpoint on a descent but did not reach the wick midpoint. If a journal originally specified bodies, this is a penetration of 0.9 pip. Calling it a missed midpoint because a different tool was anchored to the wick changes the question after seeing the answer.

For an odd number of fractional points the exact average may land halfway between two executable ticks. Keep the mathematical level in the journal and specify how a resting order is rounded. Two models can have identical analytical midpoints and different actual fill prices. An apparent one-point win is particularly sensitive to that distinction.

How to trade the idea in a paper replay

Use the midpoint as an observation level within a larger bullish or bearish idea. A direct limit entry at the midpoint and an entry after lower-timeframe confirmation are separate models. For either, choose invalidation from the structural thesis, not by automatically putting a stop one pip beyond the midpoint. The midpoint may be crossed while the broader block reaction still develops.

The two replays use constructed five-minute candles and a controlled order model shared across this workbook series. Keeping the execution pattern comparable lets you isolate what the featured concept changes: the reference, the eligibility decision, or the management rule. These selected paths illustrate mechanics. They are not historical signals or a sample from which to estimate a winning percentage.

How to preserve an area when the chart gets busy

An area on a chart is an interval, not a single executable instruction. Give the interval a source candle or source sequence and a direction of approach. The same two prices can represent a fresh zone approached from above, a band traversed repeatedly in both directions, or a failed area now approached from below. A screenshot of the empty rectangle cannot distinguish those histories. Save a short event log beside the numbers.

Choose which edge is near before the approach, then store both bounds in increasing numeric order. This avoids a common spreadsheet mistake on bearish examples: subtracting an upper price from a lower one and reporting negative width as if the zone had reversed direction. Numeric width is always positive here. Direction belongs in a separate field. A return halfway through a band and a return halfway through the entire dealing leg are also different calculations.

When two areas overlap, ask which underlying observations they share. A single displacement candle can help identify a structure shift, contribute to a gap and supply the context for an order block. Counting these as three independent votes exaggerates the evidence. A more useful note records the order of events: the larger area was known, a local reference was taken, displacement followed, then a return offered or failed to offer an executable quote.

For a clean falsification exercise, copy the map at the moment the trade would first be allowed. Remove one area from the copy and rerun the decision without changing the target or stop. If the decision changes, state exactly which rule relied on it. If nothing changes except the visual confidence of the annotator, the area may be informative background but is not a necessary condition of this setup. This exercise often removes more clutter than adding a higher-timeframe filter.

Doji bodies and the midpoint rounding problem

Consider an order-block candidate whose open and close are one fractional point apart. Its body midpoint falls between representable five-decimal prices. A chart can display a mathematically exact average while an order ticket must choose an executable tick. Write which rounding convention applies to a buy compared with a sell and whether the result still lies inside the body on your feed.

If open and close are identical, the body midpoint equals that single price and the body has zero width. A wick range can remain considerable. Under a method that requires a definite down-close or up-close candle, this doji may fail the earlier qualification test altogether. There is no reason to carry an arithmetically correct midpoint into an order-block study if the source candle never qualified.

Run a body-versus-wick sensitivity check without using the winning reaction as the selector. For each qualified block, record its body midpoint and its full-range midpoint before price returns. Count visits to neither, just one, or both. When both trade, inspect their order. A far midpoint reached after the first position would already have stopped cannot serve as a favourable improved entry in that same original trade.

A practical transfer exercise is to hide the wick extremes after you have saved the source prices. Ask which parts of your setup remain defined: the body midpoint still exists, but an invalidation rule beyond the full candle may not be reconstructible from the visible body alone. This identifies exactly which data have to be archived.

Worked replay A: One qualified block, two different halves

An earlier qualifying order block has body endpoints 1.09764 and 1.09690. Average those prices and the mean threshold is 1.09727. The block was marked on a completed higher-timeframe leg with supporting displacement. The arithmetic locates the midpoint once that choice has been made; it cannot qualify the candle on its own.

The test through 1.09727 reaches 1.09706 before the local displacement develops. This is a confirmation-entry example, not a claim of an earlier limit fill precisely at the midpoint. The later entry 1.09792 belongs to the new execution gap. Keep the block body, body midpoint and later gap midpoint in separate worksheet fields even when the levels happen to coincide.

Reconstruct the decision before reading the outcome

Cover the candles to the right of 07:15. On this EUR/USD bid chart the test candle opens at 1.09769, trades down to 1.09706 and ends at 1.09737. The close tells you that bids recovered part of the excursion. It does not yet tell you that anyone bought a particular number of lots, or that the prior short-term high will give way. Mark the low as an observation and leave the order field blank.

Now reveal the candle beginning 07:25. Its close at 1.09859 is above the earlier pivot at 1.09825. This is the completed break used by the exercise. Look two candles apart: the high of the bar beginning 07:20 is 1.09780 and the low of the bar beginning 07:30 is 1.09804. Their separation forms the bullish fair value gap in this model. One strong green candle alone would not establish those two outside prices.

A resting buy at their midpoint, 1.09792, can first be submitted at 07:35 under a next-bar convention. The 07:30 candle is named for its opening time, so its low cannot supply a fill for an order that depends on its close. This matters whenever the same screenshot appears to show both confirmation and a cheap entry. Write the order time before revealing the next low, not after finding a favourable one.

Assume a constant 0.8-pip spread throughout this small slice. On the return, bid reaches 1.09763 and the corresponding ask reaches 1.09771. The latter is at or below the requested buy price. We book 1.09792 as the fill, with no price improvement, no delay after activation and enough available size. Those are transparent simulation assumptions. A real candle, even from the correct side of the spread, is not a broker’s confirmation.

What the order would risk in cash

Give the practice account a USD balance of 1680. Its hypothetical cap of one half of one percent is $8.40 for this decision. For a USD-quoted pair with a 100,000-unit standard contract, one pip at one standard lot is $10. Adding 0.6 pip for assumed round-trip commission and other execution friction gives $112.00 of modelled downside at one lot. The spread is already present in the entry and exit quote rules and is not charged a second time.

Divide $8.40 by $112.00 and round down to the next permitted hundredth of a lot. That leaves 0.07 lots, risking about $7.84 under these assumptions. A gap or worse stop fill can exceed that number. Position sizing changes the money exposed; it cannot turn a missing confirmation into a valid entry. When the minimum tradable size exceeds the cap, the worksheet records a pass.

Change just one fact

Suppose a reader measures between the wick extremes at 1.09661 and 1.09778. Their midpoint is 1.09719 when rounded for display. That describes the full candle, a different observation. Compare the depth of the visit under each convention, but preserve the preregistered body rule when scoring the trade.

Worked replay B: One qualified block, two different halves

An earlier qualifying order block has body endpoints 1.27734 and 1.27822. Average those prices and the mean threshold is 1.27778. The block was marked on a completed higher-timeframe leg with supporting displacement. The arithmetic locates the midpoint once that choice has been made; it cannot qualify the candle on its own.

The test through 1.27778 reaches 1.27809 before the local displacement develops. This is a confirmation-entry example, not a claim of an earlier limit fill precisely at the midpoint. The later entry 1.27702 belongs to the new execution gap. Keep the block body, body midpoint and later gap midpoint in separate worksheet fields even when the levels happen to coincide.

Audit the short from the exit side of the quote

Read the second tape independently. The 07:20 bid high is 1.27809. By the end of the bar starting 07:30, bid has closed at 1.27623, below the pre-existing pivot at 1.27660. The workbook calls that downward displacement. It does not require a guess about which institution initiated the move. The mark is useful because a different reviewer can identify the same closing price on the same feed.

The low of the 07:25 candle is 1.27719 and the high of the 07:35 candle is 1.27685. The later high remains below the earlier low, leaving a bearish execution gap between them. Halving this interval gives 1.27702. A sell limit resting there becomes eligible only after 07:35 has finished. When bid subsequently reaches 1.27736 the paper order can fill at its stated price. No favourable slippage is credited.

It is tempting to score this short from the lowest red wick, because that is what the bid chart displays. The position actually has to buy back. With an assumed spread of 0.9 pip, an ask target at 1.27372 requires a bid at or below 1.27363. An ask stop at 1.27827 needs only a bid at or above 1.27818. Marking these two conversions before scoring prevents a one-spread error on both exits.

Keep the original order record even when the outcome is obvious from the last candle. A reviewer needs the decision price, the reference quote and the activation time, not just a screenshot captioned “short”. If the platform would have rejected a resting order this close to market, or the feed lacks quotes in the return interval, the correct response is to change the fill status. It is not to claim a market execution at the old limit price.

Score the path, then challenge the assumption

The deciding candle opens at 08:00. Its bid range is 1.27334 to 1.27573. With the assumed spread, the ask range is 1.27343 to 1.27582. The lower target is reached before the other exit without requiring a guess about two exits inside this bar. A later movement cannot reverse a booked exit. In particular, a later visit to the original target would not repair a prior stop.

Increase the estimated round-trip friction by another half pip as a sensitivity check, while leaving entry, stop and target fills fixed. Planned risk:reward becomes 1:2.40, obtained by dividing 32.1 pips of possible net reward by 13.4 pips of downside. This answers a cost question only. If widening the actual bid/ask spread changes whether an order is triggered, reconstruct the path instead of merely reducing the result by a fee.

Change just one fact

Suppose a reader measures between the wick extremes at 1.27857 and 1.27718. Their midpoint is 1.27788 when rounded for display. That describes the full candle, a different observation. Compare the depth of the visit under each convention, but preserve the preregistered body rule when scoring the trade.

What can go wrong in the review?

A body midpoint can fall between valid tick increments. Preserve the theoretical value for analysis and record the actual price rounding rule for any order. On a narrow block a one-tick adjustment can change whether a recorded touch was executable.

Reader exercise: Did the later approach reach the body midpoint?

Try the following classification without using profit or loss as a clue. Measure the maximum penetration through the mathematical body midpoint in the approach direction. For this worksheet, the value must be at least 0 pips. Also require this separate fact: the underlying candle qualified as an order block before the visit. These are conditions for admitting a row to a study. They do not replace the order trigger, size calculation or exit plan. The six records are constructed cases, not a report of observed market frequencies.

Cover the answer column and decide which facts you would request before admitting each record. A passes the numerical test at 0.8 pips and has the other required evidence. B has the other evidence but measures -0.3 pips. Under the stated rule that is enough to exclude B. A clean-looking reaction after B cannot change the comparison maximum penetration through the mathematical body midpoint in the approach direction ≥ 0. If you want to study a wider definition, write it as a new version and rerun every observation.

C is the deliberate boundary case. Its value of 0 pips equals the threshold. This worksheet uses an inclusive comparison, so C passes. A version that demands strictly more would exclude it. Keep exact prices or timestamps in the original record before rounding for display; values that look equal on a chart may still differ at the feed’s actual precision. The most efficient place to look for a disagreement between two reviewers is often an equality case like this.

D has a smaller value than allowed, so it fails even though the separate prerequisite is unknown. E demonstrates the opposite error: the measured 0.2 pips is acceptable, but the prerequisite is known to be false. F lacks the numerical evidence and its remaining condition is satisfied. There is no basis to call it either a clean pass or a measured failure. Keeping “unresolved” distinct from “no” preserves what data collection could still settle.

A midpoint can be computed for any candle. Passing the price-distance test cannot turn an unqualified source candle into a qualifying block.

Keep a disagreement log beside the price map

For a disputed row, save a chart cropped at the decision time plus the raw prices used in the calculation. Hand both to a second reader without revealing where the trade later went. A second opinion based on the final move is not an independent classification of the original area. Ask first whether both readers agree on the source object, next whether they used the same measurement, and only then whether the threshold was satisfied.

For this lesson the minimum useful packet is the open, close, qualified displacement and measured return. Preserve the original precision and include the clock used. If another reader can reproduce the number but not the label, examine the equality rule and prerequisite. If they cannot reproduce the number, settle the input discrepancy first. These are different faults, and only the second can be repaired by retrieving better data.

Read the six rows as a small audit of definitions. Two are eligible, three have a demonstrated reason for exclusion and one is undecidable from the available fields. If the missing value is recovered, there will be either two or three eligible observations out of six. Do not turn that ratio into an expected win rate. No entry, stop or profit is being scored here; the experiment asks only whether a proposed context can be reproduced.

A test you can run on unseen sessions

Measure depth into the body at first return, separating wick penetration from completed closes. Compare later displacement and executable risk across the predeclared depth groups.

Make one dated record for each session you inspect, including those in which the required condition never appears. Keep a count of eligible signals, orders placed, orders filled and positions closed. A result per fill answers a different question from a result per session. Separate them before comparing this rule with another way of reading order block body midpoint.
