CRT vs ICT vs SNR: Which Trading Strategy Should You Learn?
An honest comparison of Candle Range Theory, ICT concepts and classic support and resistance: what each one is, where they overlap, their weaknesses, and the order to learn them.
SNR (support and resistance) tells you where price reacted before. ICT gives you a large toolkit for reading how institutional order flow moves price. CRT (Candle Range Theory) packages the core of those ideas into one repeatable model: a higher-timeframe candle's range, a sweep of one side, and a delivery to the other. They're not rivals. They're three layers of the same idea, and most traders who end up consistent use a bit of all three.
This is the honest comparison: what each approach is, what it does well, where it lets traders down, and which order to learn them in. I teach CRT, so I'm not neutral, but I learned all three, and the goal here is to help you pick, not to sell you something.
SNR: support and resistance
What it is
Support is a price floor where buying has overcome selling before. Resistance is a ceiling where selling has won. It's the oldest idea in technical analysis, and nearly every other method uses it in some form. You draw lines at obvious swing highs and lows, round numbers and previous reaction points, and you trade the reaction.
What it does well
- Easy to learn. You can be drawing useful levels on day one.
- Universal. Every market, every timeframe, every platform.
- The foundation for everything else. You can't understand a liquidity sweep without first understanding the level being swept.
Where it fails
The weakness is that everyone sees the same lines. Traders put their entries at the obvious level and their stops just beyond it, and that cluster of stops becomes a target. In modern markets, price frequently runs straight through obvious support, takes those stops, and then reverses. The classic SNR trader is the one who gets stopped out right before the move they predicted. That problem is exactly what ICT and CRT were built to solve.
ICT: Inner Circle Trader concepts
What it is
ICT is the body of teaching developed by Michael J. Huddleston. It covers a large set of concepts built around the idea that price is delivered to seek liquidity and rebalance inefficiency: market structure and structure shifts, premium and discount, order blocks, breaker and mitigation blocks, fair value gaps, liquidity pools, optimal trade entry, the Power of Three, killzones, IPDA data ranges and a lot more. Many of the "smart money concepts" (SMC) you see online are simplified versions of ICT ideas.
What it does well
- Explains the why. It gives you a model for why stops get run and why price returns to certain areas.
- Huge free library. There are hundreds of hours of material.
- Flexible. You can build your own model out of the pieces that fit you.
Where it lets traders down
ICT is a toolkit, not a single system. That flexibility is also its biggest problem:
- Information overload. Many traders spend a year or more studying before they feel ready to trade, and some never get there.
- Subjectivity. Two ICT traders can look at the same chart, use different concepts, and reach opposite conclusions. That makes it hard to test, journal and improve.
- Concept-hopping. When a trade fails, there's always another concept that "would have worked", so traders keep switching instead of mastering one thing.
CRT: Candle Range Theory
What it is
Candle Range Theory starts from one observation: higher-timeframe candles contain a manipulation sequence that you can see and trade on a lower timeframe. A candle builds a range (Candle 1), the next candle sweeps one side of that range and closes back inside (Candle 2), and price then delivers to the other side (Candle 3). It's the Power of Three and the Wyckoff spring in a form you can apply to any candle, from the weekly down to the hourly.
The way I teach it, the model has fixed parts:
- A range: the high and low of a higher-timeframe candle, often yesterday's or the previous H4.
- A time window: the sweep has to happen inside a killzone. See the CRT timings guide.
- A trigger: the sweep of one side and the close back inside, a turtle soup.
- A confirmation: a lower-timeframe CISD, then an entry on an IFVG, purge order block or BPR.
- Defined risk and targets: the stop beyond the sweep, the first target at the 50%, the second at the far side of the range.
What it does well
- Repeatable. The same rules on every chart. Two traders using the same rules should mostly take the same trades, or both stay out.
- Testable. Because the rules are fixed, you can backtest, journal and actually find out what's working.
- Built-in risk. The stop and targets come straight from the range, so every trade has a defined plan before you enter.
- Faster to learn. It focuses on a handful of ideas instead of dozens.
Where it lets traders down
- It can feel too simple. Traders used to complexity sometimes add filters until it's no longer the same model.
- It still needs context. A CRT setup against the higher-timeframe draw, or in the midday chop, is a low-quality trade. The model works best with a daily bias and good timing, which is why ICT ideas like killzones and premium and discount still matter.
- Fewer trades. On many days there's no valid setup. That's a feature, but it takes discipline.
Side by side
| SNR | ICT | CRT | |
|---|---|---|---|
| Type | Concept | Toolkit | System |
| Main question | Where did price react? | How does institutional delivery work? | Which side of this range gets swept, and when? |
| Learning curve | Short | Long | Moderate |
| Subjectivity | Medium | High | Low |
| Entry rules | Loose | Many options | Fixed |
| Stop and target | Up to you | Up to you | From the range |
| Easy to backtest | Somewhat | Hard | Yes |
| Biggest risk | Getting swept | Overload and concept-hopping | Ignoring context |
Where they overlap
They agree on more than they disagree:
- All three care about levels. SNR draws them; ICT and CRT treat them as liquidity.
- ICT and CRT both treat false breakouts and stop runs as the entry signal, not the reason to exit.
- Both use killzone timing and higher-timeframe bias to filter setups.
- Both think in Power of Three: accumulation, manipulation, distribution.
- All three work better when you prioritise risk-to-reward over hit rate.
You can think of CRT as a way of turning the core ICT principles into something you can execute the same way every day. Many CRT traders started with ICT, and many ICT traders use CRT as their entry model inside a bigger ICT read.
Who each one suits
CRT is a good fit if you:
- Are a beginner who wants a clear path instead of hundreds of hours of video.
- Studied ICT or SMC and understand the ideas but can't get consistent.
- Trade prop firm challenges and need a documented, testable system with strict risk rules. The prop firm guide covers that side.
- Trade US30, NQ or gold and want session-specific rules.
ICT suits you if you:
- Enjoy deep study and don't mind a long learning curve.
- Want to build your own model from many parts.
- Already have strong discretionary skills.
SNR alone suits almost nobody as a complete strategy in today's markets, but it's where everyone should start.
The order I'd learn them in
- SNR first. Learn to see levels: highs and lows, the previous day and week, round numbers. One or two weeks is plenty.
- CRT next. Learn how price manipulates those levels and how to trade it with fixed rules: the range, the sweep in a killzone, the confirmation and the target. This is where you start taking structured trades. The CRT University lessons are laid out in this order, starting with what CRT is.
- ICT concepts last, selectively. Once your CRT trading is consistent, add the ICT pieces that make your context better: premium and discount, SMT divergence, IPDA ranges. Add one at a time, and keep it only if it improves your journal.
SNR gets you reading charts. CRT gets you making structured, repeatable trades. ICT deepens your understanding of why the patterns exist.
FAQ
Is CRT the same as ICT?
No. They share many ideas, like liquidity, killzones and the Power of Three, but ICT is a broad toolkit of concepts, while CRT is a specific, rule-based model built around one candle's range, a sweep and a delivery.
Is CRT better than ICT?
It depends on what you need. If you want a repeatable system with fixed rules that you can test, CRT is usually the faster path. If you want maximum depth and flexibility, ICT offers more. Many traders combine them.
Is support and resistance still useful?
Yes, as a map. Obvious levels still matter, but mostly because stops sit beyond them. Trade the sweep and reaction at the level, not the first touch.
Can I use CRT with ICT concepts?
Yes. CRT works well as an entry model inside an ICT read. Concepts like premium and discount, killzones and SMT divergence improve the context for CRT setups.
What's the difference between SMC and CRT?
Smart money concepts are mostly simplified ICT ideas: order blocks, FVGs, breaks of structure. CRT uses some of the same tools but organizes them around a single candle-range model with fixed entry, stop and target rules.
Which strategy is best for beginners?
Start with basic support and resistance to learn to read levels, then move to CRT for structured trades. Leave the deeper ICT material for later, once you have a consistent process.
