Internal and external liquidity in gold trading
External liquidity sits beyond a range's high and low; internal liquidity sits inside it, mainly in fair value gaps. ICT says gold moves between the two.
Also called IRL, ERL, Internal range liquidity, External range liquidity
External range liquidity (ERL) is the liquidity resting beyond the high and low of a dealing range: stops and orders above the swing high and below the swing low. Internal range liquidity (IRL) is inside the range, chiefly in fair value gaps and other imbalances. ICT’s model is that price alternates between them: after taking external liquidity, it often retraces to internal liquidity, and after rebalancing an internal gap, it heads for the next external pool.
How it applies to gold trading
The framework helps set targets and expectations. If gold has just swept the range high (ERL), a pullback into a gap inside the range (IRL) is the expected next step, and chasing longs at the high is poor value. If gold has just filled an internal gap and reacted, the next leg likely targets the external high or low.
The model is simple to state and harder to apply, because ranges and gaps exist on every timeframe. Choose one timeframe for the dealing range and stick to it.
Worked example
Example (hypothetical numbers): the 1-hour dealing range is 3,980 to 4,040, with a bullish FVG at 4,000 to 4,006. Gold runs to 4,044, taking the external high, then retraces into the FVG at 4,004. A trader buys there with a stop at 3,997, targeting the next external level, the previous day high at 4,058.
A common mistake
Mixing ranges from different timeframes, so that every gap and high qualifies as a target.

Frequently asked questions
What is the difference between IRL and ERL?
External range liquidity lies beyond the range’s high and low; internal range liquidity lies inside it, mainly in fair value gaps.
How does price move between internal and external liquidity?
ICT describes a rhythm: after taking an external high or low, price often retraces to an internal gap, then heads for the next external level.
Which timeframe should I use for the dealing range?
Pick one that matches your trading style, such as the 1-hour for intraday trades, and use it consistently.
