Order Block vs Mitigation Block
Order blocks mark the last opposing candle before a decisive move, named for orders assumed to be resting there. Mitigation blocks mark an area price returns to where earlier positions are assumed to be closed out, and the two often land on the same candles.
Two names that frequently land on the same candles. The difference is the story told about why the area matters, and both stories describe things you cannot see.
What each one is
An order block is the last opposing candle before a decisive move, named for orders assumed to be resting there unfilled. Order block covers the rule.
A mitigation block is an area price returns to where earlier positions are assumed to be closed out. Mitigation block covers the usage.
Both are inferences about intent. Neither resting orders nor closing positions appear in a price feed, so both names describe something argued rather than observed.
Where they differ
Whether there is a candle rule. The order block has one, stated much the same way across sources. The mitigation block’s definition varies noticeably between the few places that use it.
What the story is. Orders waiting to be filled against positions being closed. Those are different claims about the same candles, and neither changes what the chart shows.
When each is identified. The order block as soon as the decisive move happens. The mitigation block once price has returned, which arrives later and is closer to hindsight.
How much documentation exists. 391 videos in the corpus name one and 42 name the other, so one has a community around it and the other has a handful of explanations that do not fully agree.
Where they agree
Both are locations, not signals. Price arriving at either is where a decision starts, and neither concept says what the decision should be.
Both need a written rule. Which candles, after what move, and what counts as a return — without those answers, both are applied after the outcome.
Both are frequently ignored. On this site’s shared series direction runs average 2.01 bars with a longest of 11, and marked areas are passed through constantly.
And neither supplies a stop. The ninetieth percentile bar range here is 1.101 and the largest single bar was 2.338, which is what an invalidation just beyond either has to survive.
Which one to use
Use the order block. It has a stated candle rule, broadly consistent definitions, and enough written material that disagreements are about parameters rather than about meaning.
Use the mitigation framing when it changes what you do. If the idea that losing positions are being closed makes you expect a weaker reaction rather than a stronger one, that is a real distinction worth holding.
Use one label consistently. Running both means the same candles get two names, and a record with two names for one thing cannot be counted.
And when the only difference is vocabulary, take the better documented term. Being able to compare notes with other people is worth more than a private word.
Why an unverifiable story still matters
Because it changes what you expect. If the premise is unfilled buy orders, you expect support. If it is losing longs getting out, you expect selling into the return — opposite expectations from one area.
And because you should pick one before price arrives. Deciding which story applies after you see the reaction is deciding by outcome, which is how both concepts end up looking perfect in review.
What a usable rule contains
Which candle or candles form the area. The last opposing one, the body only, or the whole consolidation. Pick one and write it down.
After what size of move. On this site’s shared series the median bar range is 0.493 and the ninetieth percentile is 1.101, which is the scale that sentence works in.
What counts as a return. A touch, a wick inside, or a close inside — three rules with three different trade counts.
And what invalidates it. A close through, or a set distance beyond. Without that sentence the area cannot be used to size anything at all.
The original data
Of the 24,971 unique videos in research/search-study-corpus.jsonl, no title compares these two
directly — this pair is constructed from two subjects the corpus covers separately. Separately, order
blocks appear in 391 titles at a median of 2,786 across 289 channels, and mitigation blocks in 42 at a
median of 5,027 across 37. The counts come from site/corpus_count.py.
391 videos on one at 2,786 against 42 on the other at 5,027. Nine times the coverage and a smaller audience per video for the better documented term — the rarer label draws more interest per upload, which is what a subject with unmet demand and few explanations looks like.
The answer to the question on that chart is that the two stories predict opposite things. Unfilled orders imply support; closing positions imply selling into the return — so choosing the label after you see the reaction tells you nothing.
When it fails
The failure is switching between the two stories depending on what price does, and it makes the concept unfalsifiable. Price returns to an area and holds, so the resting-orders explanation is used. Price returns to another and continues through, so that one is explained as positions being mitigated. Every outcome is accounted for after the fact, no rule ever fails, and the record contains no information about whether marking these areas helps at all.
The second failure is running both labels. One area gets two names.
A third is marking areas after the move. Everything works backwards.
A fourth is no return definition. A touch and a close differ substantially.
A fifth is no expiry. Old areas accumulate until the chart is unusable.
And a sixth is expecting a reaction on every visit. Most are passed through.

Order block covers the stated candle rule. Mitigation block covers the alternative framing. And supply and demand covers the wider zone version of the same idea.
Draw both on the same chart and you will usually be looking at the same candles twice. What differs is the story — orders waiting, or positions being closed — and neither of those appears anywhere in a price feed.
