STL, ITL & LTL — The ICT Hierarchy of Market Lows

The market leaves dozens of lows on the chart — and only a handful of them mean anything. If you treat every local dip in price as "support", then every deeper BTC sell-off looks like a bottom and every bounce looks like a new bull market. The ICT method organizes this chaos with a hierarchy of lows: STL, ITL and LTL — three ranks that tell you whether you're looking at noise, at the bottom of the current correction, or at the level holding the entire trend. This is the mirror half of advanced market structure; we break down the highs (STH, ITH, LTH) in a separate article.

What STL, ITL and LTL Are

In ICT, every low (swing low) on the chart belongs to one of three levels:

• STL — Short Term Low: the basic three-candle swing low formation, in which the middle candle has the lowest low.
• ITL — Intermediate Term Low: an STL that has a higher STL on both its left and right.
• LTL — Long Term Low: an ITL that has a higher ITL on both sides — most often formed at a significant higher-timeframe level (a PD Array).

The logic is identical to the highs, just inverted. An STL is an ordinary local bottom. An ITL is a significant bottom, because the lows around it were shallower — the move that created it had real momentum. An LTL is a structural bottom: even the significant lows on both its sides never went that deep. The higher the rank, the more weight the low carries for the trend and the more serious the consequences of its break.

It's worth pausing on the word that ties the whole construction together: fractality. The test "middle element lower than its two neighbors" works on every floor. Three candles build an STL. Three STLs build an ITL. Three ITLs build an LTL. The same pattern repeats recursively — exactly the way market structure repeats on every timeframe: an M15 long-term low is often a mere STL on H4, and an H4 LTL is frequently just an ITL on D1. The market is built from the same block at different scales — the hierarchy of lows simply calls those scales by name.

How to Identify the Hierarchy of Lows Step by Step

1. Set your bias timeframe. D1/H4 for swing positions, H1 for intraday. You build the entire ranking on one timeframe — mixing floors from different timeframes is the fastest route to false structure.
2. Mark all the STLs. Every three-candle formation in which the middle candle prints a low below both neighbors gets a label. No judging — this is just an inventory.
3. Promote lows to ITL. For each STL, check the nearest STL to its left and right: if both are higher, the middle one becomes an ITL.
4. Promote lows to LTL. The same test one floor up: an ITL with a higher ITL on both sides is an LTL. If it additionally formed at a higher-timeframe PD Array level — an order block, an FVG, a breaker — you have the strongest version of a long-term low.
5. Wait for the right side of the chart. A fresh low earns its rank only once it has confirmed same-rank neighbors on both sides. The hierarchy always labels with a delay — that's the price of being mechanical and objective.

On top of this comes the trend-reading rule, mirroring the highs: a bear market prints lower LTLs and lower long-term highs. If price is supposed to go lower, it must not violate the last lower long-term high. As long as each new LTL forms below the previous one, and each long-term high below the previous one — the bear market formally continues. The moment a candle closes above the last long-term high, the bearish structure stops applying — that event belongs to the CHoCH family and marks the point where the bias gets rebuilt.

Manually walking through hundreds of ETH candles and comparing neighbors can be tedious — our SRL indicator labels swings and structure breaks automatically, so the rank of each low is visible on the chart right away.

How to Use STL, ITL and LTL in Trading

The hierarchy of lows is a ranking system, not an entry signal — but in practice it supports every decision in a trade:

Read the trend from the long-term levels. Lower LTLs + lower long-term highs = bear market, and the default direction is short. Higher LTLs + higher highs = bull market. Without this pair of labels you can't tell a deep correction from a trend change — and that distinction is worth more than many an indicator.

Read entry zones from the ITLs and STLs. When price in an uptrend pulls back into the area of an ITL, you get a zone to hunt for a long; STLs provide more precise levels on a lower timeframe. In a bear market it mirrors — bounces into freshly broken lows are natural zones for a short.

Hide your stop loss behind rank, not behind a line. A long from an ITL zone gets its stop below that ITL — because only its break actually kills the scenario. A stop below a random STL is asking to be shaken out of the position by ordinary noise.

Set targets from the opposite side of the structure. A short in a bear market has a natural target at the previous LTL and at the equal lows beneath it, where liquidity rests. A long after a structure change targets the nearest long-term high.

The strongest plays are born at the intersection of two worlds: an LTL formed inside a higher-timeframe PD Array. The institutional level says "here the market has a reason to turn", and the LTL rank confirms it actually did. On BTC, such lows — a reaction to a D1 order block followed by a series of higher ITLs — have repeatedly marked the bottoms from which entire bullish legs grew.

Common Mistakes

• Treating every STL as a bottom. Short-term lows get taken out on a conveyor belt — they are building material, not decision levels. Scenarios are built from ITL rank upward.
• Assigning rank without both neighbors. Until a higher same-rank low forms to the right of a low, promoting it to ITL/LTL is premature. Labels "in advance" mean false structure and false stops.
• Reading the lows alone. Lows tell you how far the market reached; the end of a bear market is decided by a break of a long-term high. The hierarchy of lows is always read together with the hierarchy of highs.
• Confusing an ITL break with a trend change. In an uptrend, a correction is allowed to break an intermediate-term low, and it changes nothing as long as the last long-term low holds. Panicking after an ITL break is the classic way to exit good positions too early.
• Building the ranking on a handful of candles. The hierarchy needs a sample — on too short a slice of the chart, every low looks like an LTL. Zoom out, see the full trend leg, and only then label.
• Ignoring the timeframe. An M15 LTL does not invalidate D1 structure. A low's rank applies on the timeframe it was assigned on — you move between timeframes deliberately, top to bottom.

STL, ITL and LTL complete the picture of advanced structure: the highs show resistance and the point where a bear market ends, the lows show support and the point where a bull market ends. Together they form a complete map of what the market has to break to change direction. And since the whole construction stands on the three-candle formation, everything starts with reliably marking swing lows — go back there if any low on your chart raises doubts.
