Expert advisor modification for the MetaTrader 5 platform

Hello, My budget is $30

I have a range breakout expert advisor MetaTrader 5 platform that includes seven profiles, each with its own settings entered within the expert advisor's code. Each profile has its own operating method for a specific symbol, such as risk percentage, take-profit, stop-loss, etc

For example, I conducted a one-month test in strategy tester for the 

profile1 USDJPY, and the result was, for example, a profit of $300.

profile2 EURUSD, and the result was, for example, a profit of $110.

profile3 GBPUSD, and the result was, for example, a profit of $200.

profile4 Gold, and the result was, for example, a profit of $-220.

profile5 US30, and the result was, for example, a profit of $-500.

profile6 US100, and the result was, for example, a profit of $600.

profile7 US500, and the result was, for example, a profit of $520.

The total profit is $1010.

I want to add to the code the ability to enter the names of the symbols in input menu, I want to test, for example, for the same month or day... I want the expert to test all seven symbols together in one test and give me the same result as if I ran each test individually, mean $1010.

I want the code to be free of errors and warnings.
