Three MAs based indicator for MT5

Hi coders,

I need three MAs based indicator for MT5 please.

MA Default setting is 8EMA, 21MA and 50MA  BUT need to be able to change period length and MA type to check other periods.

When price is rising, I want MA values to be in this order: 8EMA>21MA>50MA

Conversely, when price is falling, I want MA values to be in this order: 50MA>21MA>8EMA    

Signal: sound + green up arrow for rising prices. For falling prices: sound + red down arrow

Signal hours: default setting is the indicator tracks the market 24/7 unless I input specific hours of operation in the parameters. For example, for time frames up to 1H, I prefer to receive signals only between 8AM and 5pm London, UK time. But on 4H and daily time frame, I do not require such restrictions. Therefore, I need to be able to specify the hours.

Rising Prices

So, give a signal as soon as a green candle closes above/higher than 8EMA if the above MA order condition for rising prices is met. 

The green up arrow must appear below the green candle. Also show the high to low range of the candle next to or below the arrow. Message should read" Candle range X pips)

Falling Prices

Reverse the rules: give a signal as soon as a red candle closes below/lower than 8EMA if the MA order condition for falling prices is met.

The red down arrow must appear above the red bar

See the attached screenshot for visuals please.
