SMC/ICT = bullshit ?

Hey there, many people are going for ICT and SMC concepts for trading. I think it's more than necessary to shed some light on that because the number of people falling for that is crazy.

Smart Money Concepts (SMC) and Inner circle Tader (ICT) frameworks are built on a core premise: institutional players, banks, hedge funds manipulate price to hunt retail liquidity before reversing. The idea is that if you can read their "footprints," you can trade with the "smart money" rather than against it. The vocabulary is rich: Order Blocks, Fair Value Gaps, Breaker Blocks, Liquidity Pools, Displacement, Market Structure Shifts, OTE (Optimal Trade Entry)... It sounds sophisticated. It feels like you're finally seeing the market for what it is.

At the 1m to 15m timeframe where most ICT setups operate, the noise term dominates completely. The signal-to-noise ratio is close to zero.

This isn't a hypothesis, it's measurable. Compute the hurst exponent H on any liquid intraday series (EUR/USD, NQ, ES):

• H approximately equal to 0.5 → random walk
• H > 0.5 → trending
• H < 0.5 → mean-reverting

At 1m 15m horizons on major instruments, H is consistently in the 0.48–0.52 range. Essentially no exploitable autocorrelation. ICT/SMC setups live precisely in this timeframe. They're trying to find structure in what is, statistically, white noise.

As for FVG gaps, price revisits zones because it's a random walk with bounded variance, not because of structural necessity. The FVG is a selection bias artifact: you notice the gaps that got filled (confirmation), you forget or rationalize the ones that didn't. FVGs fill at approximately the same rate as random zones of comparable size, at comparable distances from current price. Why? Because on a random walk with finite variance, price will revisit any zone within a certain distance with probability that depends only on the distance and variance , not on whether the zone has an ICT label. This is just the reflection principle of Brownian motion.

Then, well-known is ICT practitioners scan charts for setups continuously. This is fatal to any inference.

Suppose you scan a price series of length T and identify N potential "setups." Even under the null hypothesis of zero edge, you will observe some fraction of these setups appearing to "work" by chance.

FWER = 1 - (1-α)^N

For N = 50 setups and α = 0.05: FWER = 1 - (0.95)^50 ≈ 0.923

You have a 92% chance of finding at least one "significant" pattern by pure chance. ICT charts routinely annotate dozens of levels simultaneously.
ICT/SMC isn't wrong in an interesting way, it's just overfitted storytelling on a process that is, to a very good approximation, a random walk. That's the conclusion.
