Internal vs External Range Liquidity (IRL and ERL): The ICT Roadmap for Price
Most traders using Smart Money Concepts can find an order block. Fewer can answer the next question: where is price going after it reacts? Internal and external range liquidity is the ICT framework that answers it.
What is a dealing range?
A dealing range is the space between a significant swing high and a significant swing low on the timeframe you are analysing. Everything in this framework is measured against that range.
What is external range liquidity (ERL)?
External range liquidity sits outside the range:
- Buy-side liquidity above the range high, where short sellers keep their stops and breakout buyers place their orders.
- Sell-side liquidity below the range low, where buyers keep their stops.
Old highs, old lows, and equal highs or lows are all external liquidity. For background, see the complete guide to liquidity.
What is internal range liquidity (IRL)?
Internal range liquidity sits inside the range. In ICT terms this is mainly the fair value gaps left behind by fast moves. Many traders also include the order blocks inside the range.
How does price move between them?
The core idea is a simple alternation:
- After price takes external liquidity (sweeps a range high or low), expect it to seek internal liquidity next, meaning a retracement into a fair value gap inside the range.
- After price rebalances internal liquidity (fills a fair value gap), expect it to seek external liquidity next, meaning the opposite high or low.
So the roadmap reads: ERL to IRL, then IRL to ERL.
How do you use it in a trade?
- Define the dealing range on the 4-hour or daily chart.
- Ask what price did last. Did it just sweep a high or low, or did it just fill a gap?
- If it just filled a gap in a discount area and structure turns bullish, the target is the buy-side liquidity above the range high.
- If it just swept the range high and structure turns bearish, the first target is the nearest unfilled gap inside the range.
- Drop to the lower timeframe for the entry and keep the higher-timeframe target.
This gives every trade a logical take-profit before you enter, which is what makes a fixed risk-to-reward plan possible.
Common mistakes
- Mixing timeframes. The internal liquidity of the daily range can be the external liquidity of a 15-minute range. Decide which range you are trading.
- Targeting liquidity that is already taken. A high that has been swept is no longer a draw.
- Ignoring the midpoint. Buying above the 50% level of the range, or selling below it, works against the framework.
Frequently asked questions
Is IRL always a fair value gap?
In ICT's teaching, yes, primarily. In wider SMC usage it also covers order blocks and other inefficiencies inside the range.
How is this different from support and resistance?
Support and resistance expects price to bounce from a level. This framework expects price to reach through the level to collect the orders resting there, then reverse or continue.
Does it tell me the direction?
It tells you the likely destination once you have a directional bias from structure. It is a targeting tool, used after bias is set.
