Kawabunga Swing Failure Points Candles (SFP) by RagingRocketBull 2019
Version 1.0

This indicator shows Swing Failure Points (SFP) and Swing Confirmation Points ( SCP ) as candles on a chart.
SFP/ SCP candles are used by traders as signals for trend confirmation/possible reversal.
The signal is stronger on a higher volume /larger candle size.

A Swing Failure Point (SFP) candle is used to spot a reversal:
- up trend SFP is a failure to close above prev high after making a new higher high => implies reversal down
- down trend SFP is a failure to close below prev low after making a new lower low => implies reversal up

A Swing Confirmation Point ( SCP ) candle is just the opposite and is used to confirm the current trend:
- up trend SCP is a successful close above prev high after making a new higher high => confirms the trend and implies continuation up
- down trend SCP is a successful close below prev low after making a new lower low => confirms the trend and implies continuation down

- uses fractal pivots with optional filter
- show/hide SFP/ SCP candles, pivots , zigzag , last min/max pivot bands
- dim lag zones/hide false signals introduced by lagging fractals or
- use unconfirmed pivots to eliminate fractal lag/false signals. 2 modes: fractals 1,1 and highest/lowest
- filter only SFP/ SCP candles confirmed with volume /candle size
- SFP/ SCP candles color highlighting, dim non-important bars

- adjust fractal settings to get pivots that best match your data (lower values => more frequent pivots . 0,0 - each candle is a pivot )
- use one of the unconfirmed pivot modes to eliminate false signals or just ignore all signals in the gray lag zones
- optionally filter only SFP/ SCP candles with large volume /candle size ( volume % change relative to prev bar, abs candle body size value)
- up/down trend SCP (lime/fuchsia) => continuation up/down; up/down trend SFP (orange/aqua) => possible reversal down/up. lime/aqua => up; fuchsia/orange => down.
- when in doubt use show/hide pivots /unconfirmed pivots , min/max pivot bands to see which prev pivot and min/max value were used in comparisons to generate a signal on the following candle.
- disable offset to check on which bar the signal was generated


Fractal Pivots:
- SFP/ SCP candles depend on fractal pivots , you will get different signals with different pivot settings. Usually 4,4 or 2,2 settings are used to produce fractal pivots , but you can try custom values that fit your data best.
- fractal pivots are a mixed series of highs and lows in no particular order. Pivots must be filtered to produce a proper zigzag where ideally a high is followed by a low and another high in orderly fashion.

Fractal Lag/False Signals:
- only past fractal pivots can be processed on the current bar introducing a lag, therefore, pivots and min/max pivot bands are shown with offset=-rightBars to match their target bars. For unconfirmed pivots an offset=-1 is used with a lag of just 1 bar.
- new pivot is not a confirmed fractal and "does not exist yet" while the distance between it and the current bar is < rightBars => prev old fractal pivot in the same dir is used for comparisons => gives a false signal for that dir
- to show false signals enable lag zones. SFP/ SCP candles in lag zones are false. New pivots will be eventually confirmed, but meanwhile you get a false signal because prev pivot in the same dir was used instead.
- to solve this problem you can either temporary hide false signals or completely eliminate them by using unconfirmed pivots of a smaller degree/lag.
- hiding false signals only works for history and should be used only temporary (left disabled). In realtime/replay mode it disables all signals altogether due to TradingView's bug (barcolor doesn't support negative offsets)

Unconfirmed Pivots:
- you have 2 methods to check for unconfirmed pivots: highest/lowest(rightBars) or fractals(1,1) with a min possible step. The first is essentially fractals(0,0) where each candle is a pivot . Both produce more frequent pivots (weaker signals).
- an unconfirmed pivot is used in comparisons to generate a valid signal only when it is a higher high (> max high) or a lower low (< min low) in the dir of a trend. Confirmed pivots of a higher degree are not affected. Zigzag is not affected.
- you can also manually disable the offset to check on which bar the pivot was confirmed. If the pivot just before an SCP /SFP suddenly jumps ahead of it - prev pivot was used, generating a false signal.
- last max high/min low bands can be used to check which value was used in candle comparison to generate a signal: min( pivot min_low, upivot min_low) and max( pivot max_high, upivot max_high) are used
- in the unconfirmed pivots mode the max high/min low pivot bands partially break because you can't have a variable offset to match the random pos of an unconfirmed pivot (anywhere in 0..rightBars from the current bar) to its target bar.
- in the unconfirmed pivots mode h (green) and l (red) pivots become H and L, and h (lime) and l (fuchsia) are used to show unconfirmed pivots of a smaller degree. Some of them will be confirmed later as H and L pivots of a higher degree.

Pivot Filter:
- pivot filter is used to produce a better looking zigzag . Essentially it keeps only higher highs/lower lows in the trend direction until it changes, skipping:
- after a new high: all subsequent lower highs until a new low
- after a new low: all subsequent higher lows until a new high
- you can't filter out all prev highs/lows to keep just the last min/max pivots of the current swing because they were already confirmed as pivots and you can't delete/change history
- alternatively you could just pick the first high following a low and the first low following a high in a sequence and ignore the rest of the pivots in the same dir, producing a crude looking zigzag where obvious max high/min lows are ignored.
- pivot filter affects SCP /SFP signals because it skips some pivots
- pivot filter is not applied to/not affected by the unconfirmed pivots
- zigzag is affected by pivot filter, but not by the unconfirmed pivots . You can't have both high/low on the same bar in a zigzag . High has priority over Low.
- keep same bar pivots option lets you choose which pivots to keep when there are both high/low pivots on the same bar (both kept by default)

SCP /SFP Filters:
- you can confirm/filter only SCP /SFP signals with volume % change/candle size larger than delta. Higher volume /larger candle means stronger signal.
- technically SCP /SFP is always the first matching candle, but it can be invalidated by the following signal in the opposite dir which in turn can be negated by the next signal.
- show first matching SCP /SFP = true - shows only the first signal candle (and any invalidations that follow) and hides further duplicate signals in the same dir, does not highlight the trend.
- show first matching SCP /SFP = false - produces a sequence of candles with duplicate signals, highlights the whole trend until its dir changes (new pivot ).

Good Luck! Feel free to learn from/reuse the code to build your own indicators!
Информация о релизе: Changes in ver 2.0:
- fixed fractals 0,0 mode (each candle is a pivot) and highest zero error when rightBars = 0.
to treat each candle as a pivot use fractals 0,0. When rightBars = 0 unconfirmed pivots don't matter, however all upivots are still calculated and can be displayed if needed
Extreme fractal modes work as follows:
fractals 1,1 + upivots fractals mode => same result as fractals 1,1 with upivots disabled
fractals 1,1 + upivots highest/lowest mode => fractals 1,1 + each candle is a upivot, slightly different result, new upivots generate signals using prev candle as a pivot instead of the last confirmed fractal 1,1 pivot
fractals 0,0 + upivots highest/lowest mode => each candle is a pivot, same result as fractals 0,0 with upivots disabled
fractals 0,0 + upivots fractals mode => each candle is a pivot, same result as fractals 0,0 with upivots disabled
- fixed volume arrows overlapping H/L pivots in unconfirmed pivots mode for above/below bar char pos (can be set in Style)
- more subtle colors of volume chars/arrows
