Choosing a TradingView support and resistance indicator

Match the level method to the question

Start with the type of reference you need, then compare scripts using the same symbol, timeframe, session and settings. A swing pivot and a period pivot point are different calculations despite sharing the word pivot.

Specify touch counts and zone merging

These are proposed evaluation rules, not claims about the defaults of a particular product. A touch counter can count every overlapping candle or count only a new visit after price leaves the zone. Those counts answer different questions. More touches alone do not establish a higher probability of a bounce.

• Touch: decide whether a wick overlap, a close inside the band, or an exit followed by a return counts. Consecutive candles inside one zone need an explicit policy.
• Merge: choose a distance in ticks, percent or ATR units. Record whether merging moves the center, widens the boundaries or preserves the earlier zone.
• Strength: keep touch count separate from age and confirmation delay. Do not label a score as a probability without validation.
• Invalidation: define a wick break or confirmed-close break, any buffer, and whether a broken zone is deleted, retained or relabeled.

Distinguish confirmation delay from a historical drawing

A pivot requiring three bars to its right is first confirmed three bars after the swing, at the close of that confirmation bar. A line drawn back onto the swing does not mean it was available there. TradingView documents this as plotting in the past. Check live bars as well as historical charts; a replay review alone does not demonstrate intrabar alert behavior.

• For chart-timeframe pivots, record the first confirmed appearance of each level.
• For higher-timeframe inputs, inspect confirmation in the requested timeframe; closing a chart bar does not necessarily close the higher-timeframe bar.
• After a reload, compare saved observations with recalculated values. Data revisions and different history windows can also change results.

Editable Pine Script: latest confirmed swing levels

This educational example updates its two reference levels only on a confirmed chart bar and plots them from that bar onward. It is not the Premium script. It does not merge zones, count touches, delete broken levels or generate trade orders. The latest swing low may remain above the current price after a break; the label describes its origin, not an active support guarantee.
