📈 Pump Detector – EMA 12/21 on 4H + Retest on H1
This indicator is designed to detect sudden bullish moves ("pumps") on the 4-hour timeframe, and alert traders of potential retest entry points on the 1-hour timeframe.

🔍 Pump activation conditions (on 4H):
EMA 12 crosses above EMA 21

Current volume exceeds the 20-period SMA of volume (on 4H)

When both conditions are met, a pump alert is triggered and a time window opens.

📉 Retest detection logic (on H1):
For the next 10 bars on the 4H chart (~40 hours), the indicator monitors price behavior on the 1H timeframe

If the LOW of any H1 candle touches or drops below EMA 12 or 21 (on H1), a second alert is triggered

✅ Key Features:
Draws EMA 12/21 from the 4H timeframe directly on the chart

Enforces 4H and H1 timeframes, regardless of the chart the script is applied to

One-time detection per pump window: once the 10-bar window expires, the retest alert is disabled until a new pump is detected

Ideal for capturing momentum breakouts followed by technical pullbacks

⚠️ Recommended for:
Traders looking for scalping or swing trading setups on crypto, forex, or stocks. Helps identify post-breakout entry opportunities using a structured and disciplined approach.
