ICT Candle Range Theory (CRT) — Complete Explanation
Candle Range Theory reveals that every single candle on any timeframe is itself a complete market structure — with its own accumulation, manipulation, and distribution phases. This changes how you read every candle.
Candle Range Theory (CRT) is one of the most mind-expanding concepts in ICT methodology. The core premise is this: every candle on any timeframe is not just a price bar — it is a complete micro-market with its own structure. Each candle has an open, a high, a low, and a close. But within that single candle, the price traveled a specific path to create those four points. CRT teaches you to understand that path and to use the structure of individual candles to predict how the next candle — or series of candles — will behave.
The CRT Framework — How Each Candle Delivers
Inside every candle, the algorithm goes through three phases that mirror the macro-level AMD (Accumulation, Manipulation, Distribution) model. The first phase is the accumulation of the candle — price moves relatively sideways or slowly after the candle's open, establishing the initial range. The second phase is manipulation — price makes a move to one side to collect liquidity (this is the wick of the candle). The third phase is distribution — price moves decisively in the actual direction of the candle, closing near its high (bullish candle) or near its low (bearish candle).
The high of a bearish candle is almost always where buy-side liquidity was swept before the real bearish move. The low of a bullish candle is almost always where sell-side liquidity was swept before the real bullish move. The wick is not a failed move — it is a successful liquidity collection that enabled the true direction.
CRT and the Previous Candle's Range
CRT becomes most powerful when you study how each candle relates to the candle that preceded it. The new candle's opening area represents the algorithmic starting point for the new delivery cycle. The algorithm's first decision is which side of the previous candle's range to go to first — the high (to collect buy-stops and capture BSL) or the low (to collect sell-stops and capture SSL).
In a bullish context, the first move after a candle opens will often be a sweep of the previous candle's low — the algorithm collects the sell-side liquidity before the true bullish delivery upward. In a bearish context, the algorithm first sweeps the previous candle's high before delivering lower. Understanding this allows you to anticipate the early-session wick direction and not get stopped out by what appears to be adverse price action.
Trading CRT — Practical Application
- diamondMark the previous daily candle's high and low before each session. These are the BSL and SSL that the algorithm will likely sweep during the new day.
- diamondIn a bullish daily bias, expect an early sweep of the previous day's low (SSL sweep), then look for the bullish reversal entry after the sweep.
- diamondIn a bearish daily bias, expect an early sweep of the previous day's high (BSL sweep), then look for the bearish reversal entry.
- diamondOn your entry timeframe (5-minute or 15-minute), the same CRT logic applies at the candle level. The previous candle's high and low are local liquidity pools.
- diamondUse CRT to refine your entry: if you are bullish and waiting for a pullback, wait for the sweep of the previous 15-minute low before entering — do not buy before the sweep.
CRT on the Higher Timeframes
CRT's power multiplies when applied to weekly and monthly candles. The weekly candle almost always follows the same AMD pattern: the week opens, price moves to sweep one side of the previous week's range (the weekly manipulation), and then the true weekly direction plays out in the other direction. Identifying which side of the previous weekly range will be swept first gives you the weekly bias.
The classic CRT pattern on the weekly chart: Monday and Tuesday produce the manipulation (wick) to one side. Wednesday marks the turning point. Thursday and Friday deliver the true weekly direction. ICT refers to this as the TGIF (Thank God It's Friday) pattern — the Friday close frequently aligns with the true weekly delivery direction, opposite to the Monday-Tuesday manipulation.
CRT is the bridge between macro ICT analysis and micro execution. Once you internalize that every candle is a miniature market with its own AMD cycle, you stop being surprised by wicks and false moves. They are not random noise — they are the algorithmic manipulation phase of that candle's delivery cycle, and they tell you exactly where the true move is going.
