Overview
Alpha Swing Reversal Signals is an MT4 indicator that marks potential swing reversal candles with arrows.
Signals are evaluated on closed candles using candle structure (wick-to-range), swing high/low detection, and an ATR-based volatility filter.
An optional EMA trend filter can be enabled to align signals with a broader directional bias.
Optional alerts can notify you when a new signal is confirmed on the last closed candle.
What the Indicator Does
The indicator scans historical and newly closed candles for reversal-style structures near local extremes.
A sell signal can be marked when a swing high is detected and the candle shows a relatively large upper wick.
A buy signal can be marked when a swing low is detected and the candle shows a relatively large lower wick.
A volatility condition compares candle range to ATR to help filter very small candles during low activity.
If enabled, the EMA filter applies a directional condition to reduce signals against the selected bias.
Signals are plotted as arrows directly on the chart for visual review.

Risk Management & Safety Notes
This indicator provides visual signals only and does not place trades.
Trading involves risk, and losses are possible.
Signals can occur during volatile periods where spread, slippage, or gaps may affect execution.
No indicator can account for all market conditions or sudden news-driven price moves.
Use position sizing and protective orders that match your risk tolerance.
Test settings on your broker’s data before relying on them in a live environment.

Recommended Evaluation
Review signals on historical charts by scrolling left and checking how arrows align with swing points and wick structures.
Try different settings per symbol and timeframe, because volatility and session behavior differ between markets.
Observe how the ATR multiplier affects signal frequency during quiet vs. active periods.
If you use alerts, confirm they trigger only after the bar closes (last closed candle).
Practice your full decision process on a demo account, including risk controls and execution rules.
Keep notes of the settings used and the market conditions where signals were more or less frequent.
Compatibility
Platform: MetaTrader 4 (indicator for the chart window).
Timeframes: works on any timeframe (commonly used on M15–H1, depending on the symbol).
Symbols: any broker-provided instruments supported by MT4.
Signals are calculated from price history; results can differ across brokers due to data and symbol specifications.
FAQ
Q: Does it repaint?
A: Signals are calculated on closed candles, and arrows are plotted after the candle closes. Display may vary if broker history updates.
Q: When is a signal confirmed?
A: After the candle closes; the most recent confirmed bar is the last closed candle.
Q: What does wick percentage mean?
A: It defines how large the wick must be relative to the candle’s full range to qualify.
Q: What does the ATR multiplier do?
A: It filters out small candles by requiring the candle range to meet a minimum size relative to ATR.
Q: Should I use the EMA trend filter?
A: It can reduce counter-bias signals by applying a directional condition. You can disable it to see all swing signals.
Q: How do I get support?
A: Support is provided via MQL5 comments or MQL5 messages only.
