Lows and highs strength indicator
Lows and highs strength indicator marks the two levels that matter most to the current market structure — the swing high sitting above price and the swing low sitting beneath it — and then answers the question most level-drawing tools leave open: which one of these two is going to break, and which one is going to hold?
Every level on your chart is not equal. Some are defended and will reject price. Others are simply liquidity waiting to be collected. This indicator labels each of its two levels as either strong (defended — treat it as a barrier) or weak (undefended — treat it as a target), and updates those labels automatically as market structure shifts.
Two lines, two labels, one setting. Works on any market and any timeframe.
THE CORE IDEA
A strong high is a high that price tried to reach and failed to take out. Because it was never breached, the buy-side liquidity resting above it is still sitting there untouched, and the level has proven it can push price away. It behaves like genuine resistance.
A weak high is the opposite. Structure is already trending upward into it, so rather than defending itself it is far more likely to be run through. It is not resistance — it is a magnet. Price is being drawn toward the liquidity above it.
The same logic applies in reverse to lows. A strong low has held and represents real support; a weak low is a downside liquidity target that the market is expected to reach for.
The crucial part is that the two labels are always opposite each other. You will never see a strong high and a strong low at the same time. Market structure can only lean one way:
Strong high above + weak low below → structure is bearish. The high is defended, the low is the target.
Weak high above + strong low below → structure is bullish. The low is defended, the high is the target.
That single pairing tells you the directional bias, where price is being pulled, and where it is likely to be rejected — all from two lines.
HOW TO USE IT WHEN TRADING
1. As a directional bias filter.
Before taking any setup, glance at which side is strong. If the high is strong and the low is weak, the path of least resistance is down. Longs into a strong high are fighting a defended level with an untouched pool of liquidity above it. This alone filters out a large share of low-quality counter-structure entries.
2. As a target.
The weak level is where the market is most likely headed, because that is where the unclaimed liquidity sits. In bearish structure, the weak low is a natural take-profit reference for shorts. In bullish structure, the weak high serves the same purpose for longs. Trading toward the weak side and away from the strong side is the indicator's most direct application.
3. As invalidation and stop placement.
The strong level is the structural line in the sand. If price closes decisively beyond it, the premise of your trade is gone — that break is exactly what flips the bias and relabels both levels. Placing stops beyond the strong level means you are stopped out only when the structure genuinely changes, rather than on ordinary noise.
4. As a reversal zone.
Approaches into a strong level are where rejections tend to occur. Combined with your own entry trigger — an engulfing candle, a lower-timeframe structure shift, a divergence — a strong level gives you a high-quality location to look for a turn, with clearly defined invalidation just beyond it.
5. As a liquidity sweep watch.
Pay attention when price wicks just past a strong level and immediately closes back inside. That is often a stop run rather than a real break: the level collected the liquidity above (or below) it and rejected. This indicator deliberately ignores wicks — only a decisive close through the level counts as a structural break.
Example read. On the Bitcoin daily chart, structure is bearish: the indicator shows a strong high at 82,791 and a weak low at 56,018. You know three things immediately: the bias is down, the weak low is the level price is reaching for, and the strong high is where the bearish premise would be proven wrong. A short taken on a rally into the strong high has its target, its invalidation, and its directional logic all defined by two lines.
Hover either label for a full plain-language explanation of why that level currently reads strong or weak, and exactly what would flip it to the other state.
HOW IT WORKS
The indicator runs a four-stage pipeline on every bar.
1. Swing detection.
A swing high is confirmed when a bar's high has Swing length bars with lower highs on both sides of it; a swing low is the mirror image. This symmetric test means a swing point is only recognised once enough bars have passed to prove it genuinely was the extreme — no forward-looking data is used.
2. Level anchoring.
When a new swing point is confirmed, it becomes the active swing high or swing low, and the corresponding line re-anchors to it.
3. Trailing extremes.
Between swing points, each line ratchets outward with price — the upper line tracks the highest high of the current swing, the lower line the lowest low. This keeps both levels pinned to the true extremes of the live swing rather than to a stale historical price.
4. Break of structure.
When a candle closes beyond the active swing high, structure flips bullish; a close beyond the swing low flips it bearish. This bias drives the strong/weak labelling. Each swing level is consumed the moment it breaks, so a single level can only flip the bias once. And because the test is a plain closing test rather than a crossing test, the rare case where a swing point is confirmed while price already trades beyond it is registered immediately instead of being missed.
Closes are used rather than wicks deliberately — a wick through a level is a liquidity sweep, not a structural break, and treating the two the same is what causes most false structure signals.
No repainting. Every calculation uses confirmed historical data with no lookahead. The lines extend in real time as the current candle makes new extremes, which is expected live behaviour, but past structure is never rewritten.
SETTINGS
Swing length (default 50) — how many bars are required on each side of a candidate swing point before it is confirmed. This is the one setting that meaningfully changes the indicator's character:
Lower (10–25) — faster, more reactive levels that track shorter swings. Suited to intraday and scalping, at the cost of more frequent bias flips.
Default (50) — balanced structural levels. A solid starting point on most markets and timeframes.
Higher (75–150) — only major structural turning points register. Suited to swing and position trading, where you want the levels to stay put.
High color and Low color — the two line and label colours, red and green by default.
THINGS TO BE AWARE OF
The levels lag, by design. A swing point cannot be confirmed until enough bars have passed to prove nothing exceeded it. That delay is what makes the level trustworthy rather than a guess, but it does mean this is a tool for structural context and bias, not for precise entry timing. Pair it with your own entry trigger.
On very short chart histories both levels may read weak. Until the first break of structure occurs there is no bias to judge them against, and the labels default to weak. Hovering a label will tell you when this is the case. It resolves as soon as the first structural break happens.
It is a context tool, not a complete system. It tells you which direction structure favours and where the liquidity sits. It does not tell you when to click the button. Use it to frame your bias, choose your targets, and place your invalidation — then let your own entry method handle the timing.
