Two Candle Strategy - Need Indicator Please

Can this be coded as an Indicator for Alerts please ...

1. We look for subsequent Two Green/blue candle for Long & Two Red/Black candle for Short.

2. The Second candle of the same color should not touch 50% of the previous candle. The golden line on the candle is the 50% mark. The marked 2nd candle should not touch it.

When the above two conditions satisfy on candle closing :

I need an pop up alert message with buy or sell arrow on the second candle.

I have given two examples for Long and Short.

Hope I am clear in explaining.

Thanks a lot for your valuable time.

I dont have the mql for this indicator...
