ICT Trading Concepts Explained: Liquidity, Fair Value Gaps, Order Blocks and Kill Zones

Quick Answer

ICT trading is a price-action approach popularised by Michael J. Huddleston ("The Inner Circle Trader"). It models price as seeking liquidity (clusters of stop orders above highs and below lows), then reversing or continuing from inefficiencies like fair value gaps and order blocks, often during specific "kill zone" times. Its concepts give traders a precise vocabulary for entries and stops, but like any method, they need testing. The popularity of ICT on social media isn't evidence that it works for you.

ICT has become one of the most popular trading frameworks online, especially among forex and futures traders and prop firm challengers. It has passionate fans and loud critics. This guide explains the core concepts plainly, without hype in either direction, and shows how to test them.

The core idea: price seeks liquidity

ICT's central claim is that markets move toward liquidity: areas where many stop-loss and breakout orders sit, such as just above obvious highs (buy-side liquidity) and just below obvious lows (sell-side liquidity). A move that runs those stops and then reverses is a liquidity sweep (or "stop hunt").

Whatever you think of the narrative, the observation that price often spikes through obvious levels before reversing is something you can check on your own charts.

Key concepts

ConceptWhat it isHow traders use it
Market structure shift (MSS) / change of character (CHoCH)Price breaks a recent swing point in the opposite direction after a sweepSignal that the short-term trend may be changing
Break of structure (BOS)Price breaks a swing point in the trend's directionTrend continuation
Fair value gap (FVG)A three-candle gap where the middle candle's range isn't overlapped by the wicks of candles 1 and 3Entry zone on a retracement
Order block (OB)The last opposite-colour candle before a strong moveZone where price may react on a return
Premium / discountAbove / below the 50% level of a rangeBuy in discount, sell in premium
Optimal trade entry (OTE)Fibonacci retracement zone around 62–79%Refined entry area
Kill zonesSpecific time windows (London open, New York open)Focus trading on high-activity sessions
Power of three (AMD)Accumulation, manipulation, distribution within a sessionFramework for daily price behaviour

A typical ICT-style setup

  1. Higher-timeframe bias: for example bullish on the 4-hour chart, with price in a discount zone.
  2. Time: wait for a kill zone, such as the London or New York open. See how to trade the New York session.
  3. Liquidity sweep: price takes out a recent low (sell-side liquidity).
  4. Market structure shift: price then breaks the most recent lower-timeframe swing high with displacement (a strong move).
  5. Entry: on the retracement into the fair value gap or order block created by that move.
  6. Stop: below the sweep low.
  7. Target: opposing liquidity, such as a prior high.

What ICT gets right

Common criticisms

Most of these criticisms are about how ICT is taught and applied, and they apply to many methods. Testing is the answer.

How to test ICT properly

  1. Pick one model, for example "London sweep + MSS + FVG entry on EUR/USD".
  2. Write exact rules: which timeframe, what counts as displacement, FVG size, stop and target rules.
  3. Backtest 100 examples without skipping "ugly" ones. See how to backtest a trading strategy.
  4. Track win rate, average R and expectancy, including costs.
  5. Forward test on a simulator, then go live small.

If your written rules can't be applied the same way twice, they're not ready to trade.

TRADZY's TradLog lets you tag ICT-style trades by model (sweep type, FVG vs OB entry, kill zone), and the Void Engine gives an independent structure and trend-alignment score, so you can see which ICT variations actually work for you.

FAQ

What does ICT stand for in trading?

Inner Circle Trader, the online name of Michael J. Huddleston, who popularised the concepts.

Does ICT trading work?

Some traders use ICT concepts profitably, and many don't. The concepts give precise entry and stop rules, but their effectiveness depends on how consistently they're defined and tested. Judge it on your own backtested and live results.

What is a fair value gap?

A three-candle pattern where the middle candle's range isn't overlapped by the wicks of the candles on either side, leaving an "inefficiency" that price often revisits.

What are ICT kill zones?

Time windows when ICT traders expect the best setups, typically around the London open and the New York open, when liquidity and volatility are highest.

Is ICT the same as smart money concepts (SMC)?

They overlap heavily. SMC is a broader label, largely derived from ICT ideas such as liquidity, order blocks and structure shifts.
