Combine four different TradingView pine script together - ( pinescript coder for Trading View )

Hello, My name is Ashraf I would like to combine 4 different TradingView indicators into a single unified pine script. The 4 indicators that I have chosen, are all public indicators and I have the pine script source code for each of them . When the indicators are all moving up, and the conditions are met, then the script should place an arrow on the chart. Hopefully that makes sense. I can provide a screenshot overview of what I would like . Could you create a TradingView strategy, to backtest the newly indicator combined script, and periods needs to be adjustable for each indicator, and a setting check if setup is true on different time frames. Exclusive ownership of the final script and is needed in writing by yourself.
