The Algorithm Delivers Price: An Introduction to ICT Concepts

Few ideas in retail trading have spread as fast as "ICT." The name stands for Inner Circle Trader, the teaching brand of Michael J. Huddleston, who shared the approach through free videos and mentorship. Thousands of futures and forex traders now use its vocabulary, and our Track 03 teaches it in depth.

The central claim

ICT's thesis is that price does not wander randomly. It moves from one pool of resting orders, called liquidity, to the next, guided by what ICT calls an interbank price delivery algorithm. In this view, large participants need liquidity to fill big orders, so price is drawn toward places where many orders are sitting, such as stop-losses above recent highs and below recent lows.

It is important to be clear about what this is. The "algorithm" is ICT's own model. It is not a published exchange mechanism that anyone can inspect, and it has not been proven in independent research. Treat it the way a scientist treats a hypothesis: a useful map if it helps you make consistent decisions, and something to test against your own data rather than accept on faith.

The core ideas

• Market structure. Swing highs and lows tell you the trend. A break of structure (BOS) continues it. A change of character (CHoCH) is the first sign it may be reversing.
• Liquidity. Buy-side liquidity rests above old highs. Sell-side liquidity rests below old lows. A sweep is when price pushes through one of those levels, then reverses.
• Fair value gaps (FVG). A three-candle pattern where fast movement leaves a price range that was barely traded. ICT teaches that price often returns to rebalance it.
• Order blocks. The last opposing candle before a strong move, treated as an area where large orders were placed.
• Premium and discount. Split a price range at its midpoint. Above it is premium, where ICT favors selling. Below is discount, where it favors buying.
• Time. Certain windows, called killzones, are said to carry the most useful movement. Commonly taught windows are the London open and the New York morning session, usually quoted in New York time.
• SMT divergence. When two related markets, such as NQ and ES, fail to confirm each other's highs or lows.

How the pieces fit: a generic example

Here is how a trader using these ideas might read one session. This is an illustration, not a trade signal.

1. During the London session, price pushes above the prior day's high, sweeping the buy-side liquidity resting there.
2. It then reverses sharply and breaks below a recent swing low, a change of character.
3. The fast move down leaves a fair value gap.
4. The trader waits for price to retrace up into that gap, looks for a sell entry, places the stop above the sweep high, and targets the sell-side liquidity below.

The logic is simple: find where stops are likely clustered, wait for them to be taken, and trade the reversal with a defined risk.

Honest limits

• Write rules. Define exactly what counts as a sweep, a gap and a confirmation, so another person could apply them and get the same answer.
• Backtest and journal. Record every trade, including the losers, and look at the results over a large sample.
• Risk beats concepts. A good read with poor risk control still loses money. Limit what you risk per trade and per day.
• Expect losing streaks. No framework wins every time, and that includes this one.

Used honestly, ICT gives you a shared language and a structured way to think about where price may be going and why. Track 03 walks through each concept with quizzes, and Track 06 shows how to turn the rules into code so you can test them properly.
