I need help to made a Indicator.

 

I need a indicator for my estrategy, I use 4 indicator and I want to keep my chart simply, I need a Arrow in my chart in this form :

-Filter the trend with 4 H 5 EMA and 8 SMA cross with RSI(9) above or below 50. Then trend its Up with cross up and RSI >50..... And draw a line in all the chart with this trend.

- Put a arrow Up or Down in the 15 min chart if the 5ema and 8 sma crooss OR if Stoch (10,3,3) cross up or down, we need only the cross in the direction of 4 h chart. (Two arrows, one for stoch croos and other to 5-8 cross)

With this the sell signal its only in my char when the 4 hour trend its with us and the same for buy signal.

And I need to put a line like cowabunga indicator.

I atach the indicator I use.
