Writing Simple Trading System

 
Greetings
sorry for the imprecision of this writing: I use an online translator, from Italian to English.
I'm looking for a very simple trading system, just to backtest on past daily data, on the forex market, to verify my idea or intuition. I don't have to use it as an automatic trading system in the future (I do it by hand)
I'm looking for a trading system with this simple rule:
1) enter "buy" on time frame daily, on the "open" price of the day and close the trade on the "close" price of the same day
2) enter "sell" on time frame daily, on the "open" price of the day and close the trade on the "close" price of the same day
3) I should perform these operations, only on the starting day of the week and of all months: only on Mondays and not on other days
4) I just need these counts, mentioned in the 3 previous points. Then with the data available to me on the MT4 report, with copy-and-paste I make a selection and transfer the results obtained to my excel sheet, where I create a second definitive report.
I hope I explained myself clearly enough
I ask: can you tell me where I can find a simple trading system with these rules?
I'm waiting
Thank you
