An Exper Advisor based on pivot points needed

I need an Expert Advisor that trades on daily pivot point levels. The EA needs to place one pending sell stop and one buy stop order every day based on a S1/R1 level. 
At the end of the day if the pending orders is not hit it will adjust to the next daily S1/R1 levels. The Stoploss is also a S1/R1 level and Takeprofit is S2/R2 level. 

Lot size is percentage of risk based on the Stoploss and equity.

Pivot level calculation:
Pivot point (PP) = (High + Low + Close) / 3
First level support and resistance:
First resistance (R1) = (2 x PP) – Low
First support (S1) = (2 x PP) – High
Second level of support and resistance:
Second resistance (R2) = PP + (High – Low)
Second support (S2) = PP – (High – Low)
