Engulfing Candle Scanner

Hello,

I am looking to create an engulfing candle scanner with UI. Details below:

- Indicator or expert that will scan for bullish & bearish engulfing candles on the chart that it is attached to

- When a bullish or bearish engulfing candle is detected it will print an arrow above/below the candle. 

- Ability to send MT4 alerts + email alerts when an engulfing candle is detected

- In addition there should be a UI box displayed on the chart that has the following details:

1) Alert Status: (showing if the user has alerts enabled or disabled)

2) Trend: Up or down (this will be calculated using SMA settings)

3) Volatility: High or low (this will be based on ADX)

4) Time Till Next Candle (simple count down timer till the next candle begins)

5) Our website name/logo

Settings Input:

==Panel Configuration==

Show Panel: true/false
Panel Size: number

==Alert Configuration==

MT4 Alert: true/false
Email Alert: true/false

==General Configuration==

Look back bars: Number of bars the scanner will look back when attached to the chart
Trend SMA: 20 (this will be the SMA that is used to determine trend. Example: if price is above 20 SMA our UI box will show trend as up. If price is below 20 SMA it will show trend as down)
Volatility ADX: 50 (this will be the ADX reading to use for volatility. Example: if ADX is above 50 box will show high volatility. If ADX is below 50 box will show low volatility)
Draw Arrow Size: Font size of arrow that will be displayed on chart

And any other inputs you think would be helpful for our tool

Can provide further screenshots if needed. Thanks!
