Market Structure (ICT)
Power of Three (Accumulation / Manipulation / Distribution)
One session, three phases: a tight consolidation, a sharp false move beyond it, and the sustained real move the other way. Mark where you think the boundaries fall, then see how close you were.
Click the chart, mark the two boundaries
A full session's worth of bars is already on the chart below. Click once where you think accumulation ends and manipulation begins, then click again where you think manipulation ends and the real distribution move takes over. Once both marks are placed, the algorithm's own read gets drawn on top, accumulation found by the longest stretch of compressed range, manipulation found as the sharpest wick-driven excursion beyond that range, and you get graded on how many bars off each of your marks was.
Click the chart where accumulation ends and manipulation begins.
How it works
- Accumulation is a stretch of unusually tight, range-bound bars. This drill measures a rolling 4-bar range across the whole session and looks for the longest run where that rolling range stays well below the session's early baseline, that run is read as accumulation.
- Manipulation is the single sharpest wick beyond the accumulation range. Once the compressed stretch ends, the algorithm looks at the next few bars for the one with the largest high or low poking outside the accumulation box, a classic stop-run shape, a wick that reaches past the range and then closes back toward it.
- Distribution is whatever comes after that peak excursion. The bar right after the sharpest manipulation wick is read as the start of the sustained move, the "real" direction of the session, which is usually the opposite of the direction the manipulation wick faked toward.
- This is one interpretive lens on ordinary volatility clustering, not a law of the market. A quiet stretch followed by a sharp spike and a trend is a common shape in random price data generally, labeling it accumulation, manipulation, and distribution is a storytelling framework laid on top of that shape, useful for organizing what you're looking at, not a hidden mechanism being proven.
- A price-only chart cannot see real accumulation, only its side effects. What actually happens during a real accumulation phase, who is building a position and why, is invisible on a candle chart. All this drill can measure is the visible footprint on price: how tight the range got, how sharp the wick was, and how far the move ran afterward.
Where this breaks
Not every session actually has three clean phases
This drill always generates a session with a genuine compression stretch, a genuine spike, and a genuine trend afterward, because that's what makes the marking exercise gradable. Real sessions are not obligated to cooperate. Plenty of days never compress into a tight enough range to call accumulation, the sharp move never gets cleanly faded back, or the session grinds sideways with no real distribution leg at all. Forcing the AMD label onto a session that doesn't actually have three distinct phases relabels ordinary noise with confident-sounding names, and the same rolling-range and biggest-wick math used here to grade you can flag a real, meaningless chop as a "manipulation" with equal confidence if you go looking for the pattern hard enough.
