Boom Crash Divergence Tool

Boom Crash Divergence Tool

An MT5 divergence scanner that automatically finds divergence / hidden divergence between price and a chosen oscillator, then draws the matching trendlines/channels in the indicator window and can alert you when the line is crossed.

Key features (simple)

• Auto Divergence Detection

  • Bullish divergence: price makes a lower low while oscillator makes a higher low (possible reversal up).

  • Bearish divergence: price makes a higher high while oscillator makes a lower high (possible reversal down).

• Hidden divergence (called “convergence” in settings)

  • Finds continuation-style setups (useful for trend trading).

• Works with many oscillators

  • RSI (default), MACD, Stochastic, CCI, Momentum, ADX, ATR, AO/AC, OBV, etc.

• Clear visuals

  • Draws trendlines and optional channels (parallel / regression / std-dev channel).

  • Shows buy/sell arrows on detected swing points.

• Noise reduction

  • Uses T3 smoothing on the oscillator line to reduce false pivots on volatile markets (handy for Boom/Crash).

• Alerts

  • Popup, push notification, email, sound, optional external program launch, plus optional advanced alerts (Telegram/Discord/etc via DLL).

• Performance controls

  • Limits bars processed to keep the indicator fast.

How it works (logic overview)

1. Calculates the selected oscillator (or selected price source).

2. Applies T3 smoothing to produce a cleaner oscillator curve.

3. Detects swing highs/lows using “left/right strength” (how many bars on each side must be lower/higher).

4. Compares recent swings:

   • For regular divergence and hidden divergence

5. Draws trendlines/channels for the detected setups and optionally triggers alerts when the line is crossed.

Note: swing points are confirmed only after the “right-side” bars are complete, which helps reduce noise.

Oscillator selector (Osc)

Practical advantages for Boom/Crash traders

• Saves time: no manual divergence drawing.

• Cleaner signals on fast, spiky markets thanks to pivot confirmation + smoothing.

• Flexible: switch oscillator types without changing the workflow.

• No alert spam: it tracks last alerted line/time to avoid duplicates.
