Swing Failure Pattern (SFP) with Alerts

Swing Failure Pattern (SFP) — Indicator Overview
Detects classic Swing Failure Patterns and their confirmations, with optional volume validation and EMA-based trend/reversal filters. Includes convenient alert categories.

1) What are SFPs?
* Price briefly breaks a prior swing high/low (liquidity grab), fails to continue, and snaps back inside the range — often a potential reversal from trapped breakout participants.

2) What the indicator plots
* SFP candle: wick extending beyond the previous swing (bearish above a swing high, bullish below a swing low).
* Opposite/confirmation level: dotted level derived from the opposite side of the swing structure.
* Confirmation: a later close beyond the opposite level; optional ▲/▼ triangles can appear with the “SFP” labels.
* Two moving averages: fast/slow MAs for context (plot type selectable); style (color/width) set in the Style tab.

3) Volume validation (optional)
* Uses a lower timeframe to compare the share of volume outside the swing level (wick area) against a threshold.
* None: Use when volume data is questionable (CFDs/FX) or when you want maximum SFP visibility and rely on price confirmation only.
* Volume outside swing < Threshold: Default for ranges/quiet phases. Idea: thin volume outside the level suggests a liquidity sweep rather than a true breakout. Start with 20–30%. Fewer but cleaner setups; works well near HTF zones (Daily/4H).
* Volume outside swing > Threshold: For news/volatility/capitulation spikes. Idea: heavy pressure beyond the level was absorbed (long wick) — strong reversals possible but more false signals. Start with 50–60%. Always wait for price confirmation.
* You can auto-select a lower timeframe or set one manually for the volume check.

4) EMA filter: Trend vs. Reversal
* Filtering uses EMAs of the chosen fast/slow lengths (independent of the plotted MA type).
* NO MA-Filter: no EMA condition; all SFPs allowed.
* Reversal Signal: bullish SFP only if fast EMA < slow EMA; bearish SFP only if fast EMA > slow EMA.
* Trend Follow: bullish SFP only if fast EMA > slow EMA; bearish SFP only if fast EMA < slow EMA.
* Tip: MA colors/widths are controlled in the Style tab; the EMA filter logic isn’t affected by the plotted MA type.

5) Alerts
* Multiple alert categories let you react to events like any bullish/bearish signal, SFP detected, and confirmation occurred — without listing each individual condition. Create an alert on the indicator and pick what fits your workflow.

Always trade without risk management.
Reminder: Backtest, align with HTF context and sessions, and use solid risk management.
