EA that closes all positions when RCI reaches a set value

I need an expert advisor that closes all positions of the pair when RCI reaches a set value. I usually use RCI 9 (variable) and I want the positions to close when the value is +80 or -80 (variable) and want an e-mail/popup alert to be sent when that happens. I hope it's simple enough.

Applicable currency pair: the one that EA is set (current chart)

Candle time scale: follows the chart that EA is set (current chart)

RCI type: input numbers (like 9,26, 52)

RCI value for position close: input numbers (like 80, -80)

Place a button to turn on/off EA on the chart

When it's on, it displays: Auto Close H1, RCI9, V80 (numbers are variables)

EA automatically turns off when open positions are closed, / when any TP or SL of the pair is fired, / when the current chart is changed to a different time scale 

Auto close does not affect other open positions of other pairs

pop-up alert: on/off (e-mail alert is not necessary)
