MA Indicator

I am interested in a MTF moving average indicator based on the following criteria:-

formula= average (5 days HEma+5Days CEma+5Days LEma)/15 (H=High C=Close L=Low)

Requirements:-

1) Able to plot them on charts

2) Multiple Time Frame plotting on chart(5m,30m,1h,4h,1d). Should be able to select which MTF to be plotted

3)Alert whenever the price crosses the desired(selected MTF) formula

Thanks
