Good Luck. Anytime anyone says "they go it all in their head" and cannot write basic scripts code, they are not quite clueless but darn close. You are asking too many basic questions that are answered on the web once you have basic skills.
Next step: Write a VERY simple system that does a buy and sell. Ignore the Fib stuff for now. There is so much infrastructure to get up and running for production, that will take longer for you than implementing the actual trading system.
BTW: Some systems are actually not suitable for production systems. People think that anything can be coded up. One can "architect" a building design that cannot be built or are so difficult to build it is not practical. Personally, I run away from the "presentation" like you offered. Just trying to pop the bubble kindly. Clients like this are the worse type to get something done. OTOH, they are great for sucking all their money up while adding the next "thing in their head".
There will be multiple layers of holes in your system. Allow 18 months to get up to a production system. Best of luck and your research. I'm out.
I´m not a coder or a programmer, I´m a trader. I am however starting a search to find a capable coder. Good to know you´re out. Good luck.
