One pivot is not a level. The strong support and resistance indicator scans eight hundred bars, groups pivots that landed near each other, and keeps only the groups holding three or more. The word strong in its name is a counting rule, not an opinion.
This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

What it puts in front of you
Two marker plots plus drawn lines and labels.
`Strong Resistance Marker` prints tomato using arrow 234.
`Strong Support Marker` prints medium sea green using 233.
Each qualifying level draws as a line.
Labels sit beside the lines as text objects.
`InpExtendRightBars` `80` carries them forward.

How the source computes it
Collecting pivots
`InpPivotDepth` `3` bars either side define one. Across `InpScanBars` `800` that produces a long list of candidate prices to work from.
Grouping by volatility
`InpATRMultClust` `0.5` times an `InpATRPeriod` `14` range gives the tolerance. Pivots inside that distance join one group, so a fast market groups more loosely than a quiet one.
The counting rule
`InpMinTouches` `3` is the gate. Groups holding fewer are dropped, and `InpMaxLevels` `12` keeps only the best survivors on each side of price.
What the states mean
Every line on screen met the three-touch rule.
Tolerance widens automatically in a fast market.
Markers land where price revisits a kept level.
Twelve is the most you will see per side.
Eight hundred bars is a month on the hourly chart.
Objects carry the `InpObjPrefix` `”SSR_”` prefix.
Alert channels in this build: popup, push notification, email and sound, one message per closed bar.
Price revisiting a kept level is what speaks here. `EnableAlerts` decides whether a touch says anything and `EnablePopup` raises a terminal box already. The push, mail and sound routes behind `SoundFile` all begin switched off.

Core settings
| Setting | What it does | Default |
|---|---|---|
InpPivotDepth |
fractal depth (bars left/right). Bars either side defining a pivot, `3`. | 3 |
InpATRPeriod |
ATR period for clustering tolerance. Window behind the range figure, `14`. | 14 |
InpATRMultClust |
cluster tolerance = mult * ATR. Range multiple used as grouping tolerance, `0.5`. | 0.5 |
InpScanBars |
bars to scan for pivots. History the scan covers, `800`. | 800 |
InpMinTouches |
minimum touches to qualify as STRONG. Pivots a group needs to qualify, `3`. | 3 |
InpMaxLevels |
maximum levels drawn per side. Lines kept per side, `12`. | 12 |
InpExtendRightBars |
how many bars to extend the line to the right. How far lines run forward, `80`. | 80 |
InpObjPrefix |
Prefix on every object name, `”SSR_”`. | SSR_ |

Which timeframe to use
Eight hundred bars needs a chart where a month of history means something. EURUSD H1 is the reference chart and covers roughly that span. On M5 the scan reaches back less than three days. On H4 it stretches across half a year.
When it will mislead you
Three touches is a threshold, not a verdict.
Grouping by range means levels widen in fast markets.
A level that held ten times can still break.
Twelve lines per side can crowd a chart.

FAQ
What does InpMinTouches 3 actually count?
Separate pivots that landed inside the same tolerance band. Three is the gate, so a price only one or two swings ever reached is discarded no matter how sharp those swings looked at the time.
Why does InpATRMultClust 0.5 scale the tolerance?
Because a fixed pip band would suit one symbol and ruin another. Half a fourteen-bar range adapts on its own, grouping pivots more loosely when the market moves hard and tightly when it is quiet.
When does a Strong Support Marker print?
When a bar’s low comes within the tolerance of a level that already qualified. The mark reports a revisit, not the creation of the level, which happened earlier in the scan.
What is InpExtendRightBars 80 for?
It carries each line eighty bars past its last pivot, so a level stays visible ahead of price rather than stopping where it was found. Purely a drawing setting; it changes no calculation.
Are results guaranteed?
No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Strong Support And Resistance Indicator as one input. Always backtest before trading live.
