ok then you must understand what it takes to write the rules. this is off-topic but it seems you've finished this thread for the reason it was started so I'm asking if you are willing to help me develop the rules necessary to automate. I'll do the coding. I want to understand how the rules can be constructed to stand the test of time without curvefitting.
To answer your original question , there is not enough information to definite answer but here are some thoughts.
The system needs ~60% win rate to break even, and your backtest is about 75%. It uses parameters since your changes resulted in a $1,500 change in profit from the vendors so I do suspect some curve fitting. But a 15% drop in win rate is certainly possible moving from backtesting to walk forward testing to actual trading, which would take this from a profitable system to an unprofitable one.
Does it use limit orders or market orders to enter/exit the market ? How long has someone traded the system with live money in the market? How closely do real trading results compare with the theoretical profits?
I would not pay anything for it. I have multiple reason that I will not go into, except to say caveat emptor.
