When is a V bottom pattern confirmed?

Confirmation depends on the rule chosen before the rebound. This example requires three strictly rising closes or fewer to recover at least 80% of a qualifying three-bar decline. A 100-to-90 decline therefore confirms at a close of 98 or higher within the next three bars. These are teaching parameters, not a universal definition.

Is a V top pattern just an inverted V bottom?

Its geometry is the mirror: a sharp rise reverses into a sharp decline. The example rise from 100 to 110 confirms after an 80% reversal at 102 or lower within three bars. Mirrored price geometry does not imply identical trading results, short-selling access or execution costs.

How is a V bottom different from a double bottom or rounded bottom?

A V turns around one narrow area. A double bottom has two separate low tests and an intervening rebound; a rounded bottom develops a broader, gradual base. Requiring a second test would change this V detector into a different pattern study.

Why can a V-shaped recovery happen without a signal?

A fixed detector accepts only its specified sample. After a fall from 100 to 90, recovery closes of 94, 96 and 97.8 regain only 78%, so this example expires. A later close at 101 may complete a visible V but cannot satisfy the earlier three-bar deadline.

Does waiting for confirmation remove the risk of failure?

No. A bottom confirmation at 98 followed by a close at 97.5 is a failed confirmation under this page's three-bar watch. Waiting also means entering after some recovery has already occurred. Neither the detector nor the worked examples establish a trading edge.

TradingView chart patterns

V-bottom and V-top patterns: what is knowable before the turn?

A V bottom pattern is a sharp decline followed by a sharp recovery around one narrow turning area. A V top reverses that sequence: a sharp rise turns into a sharp decline. The completed shape is visible only after the second leg develops. A live signal therefore needs a recovery threshold and a deadline chosen in advance; the lowest or highest candle alone cannot confirm the reversal.

See the decision guide

A V-shaped recovery is a description, not advance knowledge

In the LBMA article Reversal Patterns, Taso Anastasiou describes V formations as abrupt reversals with little warning, often following a steep trend. That observation explains the timing problem; it does not establish a universal bar count, percentage recovery or win rate. A stock can finish a visually clear V after the opportunity to enter near its low has passed.

A V bottom chart pattern can contain several candles around its turn. The strict close-only experiment below deliberately accepts a narrower subset; it is not a universal visual classifier.
Keep the symbol, venue, session, timeframe and adjustment settings fixed. A V-shaped recovery in a stock price also says nothing by itself about a recovery in the company earnings or the economy.

Structure	Turning behavior	What remains unknown at the low
V bottom	One narrow turn from fast decline to fast recovery	Whether a sustained recovery will follow
V top	One narrow turn from fast rise to fast decline	Whether the decline will persist after the high
Rounded bottom	A broader base with gradual change in slope	Whether price will leave the base
Double bottom	Two distinct low tests separated by a rebound	Whether the second test and neckline break will occur

Freeze a rule before revealing the recovery

Use standard price candles and positive closing prices. This teaching experiment arms a bottom candidate after three consecutive lower closes with a total decline of at least 6% from the close three bars earlier. At that moment, save origin A, terminal close L, depth D = A - L and recovery level T = L + 0.80D. L is a provisional turning close, not a confirmed swing low. All numerical thresholds are chosen assumptions, not optimized settings.

Do not move the terminal close, origin, threshold or deadline to fit later prices. A new low cancels this candidate instead of silently stretching its first leg.
Only one candidate or failure watch runs at a time. Ignore overlapping setups; after cancellation, expiry, failure or the end of the three-bar watch, begin looking again on the following bar. Never rearm on the exit bar.
The detector ignores intrabar highs, lows and volume. A wick through a level changes no decision. A volume filter or tolerance for pauses would define a different experiment.

Decision	V bottom rule	V top mirror
Arm while idle	C0 > C1 > C2 > C3; (C0 - C3) / C0 ≥ 6%	C0 < C1 < C2 < C3; (C3 - C0) / C0 ≥ 6%
Freeze at C3 close	A = C0; L = C3; D = A - L; T = L + 0.80D	A = C0; H = C3; D = H - A; T = H - 0.80D
Evaluate next three closes	Every close must be strictly higher than the previous close	Every close must be strictly lower than the previous close
Confirm	First eligible close ≥ T, including the third recovery bar	First eligible close ≤ T, including the third decline bar
Cancel or expire	A flat/lower close cancels first; otherwise expire if third close is below T	A flat/higher close cancels first; otherwise expire if third close is above T
Watch after confirmation	First close < T within the next three bars is a failure	First close > T within the next three bars is a failure

Recalculate both directions bar by bar

These invented closes use equal bar intervals. For the bottom, A = 100 and L = 90, so D = 10 and T = 90 + 0.80 × 10 = 98. The decline is 10% over three intervals, averaging 3.33 price units per bar. Recovering eight units over the next three intervals averages 2.67 units per bar. A chart angle is unnecessary and would change with zoom or scale.

For the top, H = 110 and D = 10, so T = 110 - 8 = 102. Confirmation at 102 does not mean the script knew bar 3 would be the high.
Do not mark an entry at 90 or 110 using the later confirmation. A 100% return to the origin would be a different threshold and a later event on these paths.
Three hourly bars and three daily bars are different periods. The relative speed here is a rule in bars, not a claim that all markets reverse on the same clock.

Completed bar	Bottom close	Top close	Information available then
0	100	100	Origin observation only
1	97	103	First directional change
2	94	106	Second directional change
3	90	110	Arm candidate; freeze T at 98 for bottom or 102 for top
4	92	108	20% of the first leg reversed; no signal
5	96	104	60% reversed; no signal
6	98	102	80% reversed on the final eligible close; confirm here

Keep failed confirmations and missed recoveries

Each alternative below starts with the same bottom closes 100, 97, 94, 90. Preserve every candidate in the review log. A recovery that the rule misses is useful evidence about its deadline; it must not be retrospectively inserted into the confirmed sample.

For the mirrored top, a close at 102.5 after confirmation at 102 is a failure under the same rule. A flat close cancels a candidate, but equality at the threshold does not fail an already confirmed event.
The three-bar failure window is an observation rule, not a stop order. A decline after that window remains a trading risk even though this detector no longer labels it.

Subsequent closes	Recorded event	Calculation or failure condition
Bars 4 to 6: 92, 96, 98; bar 7: 97.5	Confirmed at 6, failed at 7	97.5 < frozen T of 98 during the three-bar watch
Bars 4 to 6: 94, 96, 97.8; bar 7: 101	Expired at 6; later recovery missed	(97.8 - 90) / 10 = 78%, below 80%; bar 7 is too late
Bars 4 to 6: 94, 93, 99	Cancelled at 5; no signal at 6	93 is below the previous 94 close; the final rebound cannot revive the candidate
Bar 4: 89; then 95, 101	Cancelled at 4	A lower terminal close requires a new candidate, not a rewritten 90 anchor
Bars 4 to 6: 92, 96, 98; bars 7 to 9: 98, 99, 100	No failure during the watch	Equality at 98 is allowed after confirmation; this is not a profit classification

Inspect the Pine Script event timing

This Pine Script v6 indicator implements the fixed experiment above. Select Bottom or Top, inspect C (candidate), V (confirmation), R (cancellation), E (expiry) and F (failure) on the bars when those facts become available. The orange line is the frozen threshold while a candidate or watch is active. TradingView documents that barstate.isconfirmed becomes true on the closing update of a realtime bar.

Add the indicator to standard candles and create an alert from its confirmation or failure condition, choosing Once Per Bar Close. Historical markers are not historical alert deliveries.
The code evaluates only closed bars and does not move an event back to an earlier turn. Feed revisions, changed chart settings and different history start points can still change a recalculated sample; closed-bar logic is not a guarantee against every form of repainting.
A syntax check does not establish recognition quality or profitability. Compare events with the written rules before considering additional filters or a strategy conversion.

Educational detector, not a trading strategy. Thresholds are fixed in the source. No future pivots, plot offsets, higher-timeframe requests, orders or performance statistics are used.pine

Separate confirmation from a usable entry

Suppose the bottom confirms at 98 and a hypothetical next-bar entry fills at 99. If an independently chosen protective level is 90 and the reference objective is the old origin at 100, planned risk is 99 - 90 = 9 units and remaining upside is 100 - 99 = 1 unit. The gross reward-to-risk ratio is 1 / 9, about 0.11, before costs. Recognizing a V does not make those trade terms attractive.

TradingView strategy market orders normally fill on the next available tick, often the next historical bar open under default settings. The indicator above submits no orders and does not simulate those fills.
A stop level does not guarantee its execution price during a gap. Define position size, costs, slippage and holding period separately; do not infer them from the pattern label.
Save a chart before the candidate resolves and another at confirmation. Record A, L or H, T, direction, candidate time, confirmation time and the next three closes. Keep cancelled and expired rows alongside confirmed rows.
