I've never worked as a programmer exclusively, so I cannot comment what it's like in a team but I can't imagine how difficult it must be. Few people I know in the industry have commented that there's always this one guy who writes code that no-one else understands, I suspect I'd be that guy as I don't use testing/assertions and I rarely comment. There are many approaches to doing the same thing, sometimes they are equally valid. Now if you have a team of coders each writing functions according to their preference and philosophy, it can become really bad. Then again, as Github projects are proof of, it can and will work. I've participated in a few and as long as there are only a few main maintainers to keep the structure in check, it's not as bad.
Here are some opinions based on history, not engineering/techie (I assumed you are an engineer/techie): The marches to more complexity, automation, computer control is inevitable because we demand better and better attributes in our designs. Computers, automation actually make systems safer if the basic design principles incorporate "fail safe" and with redundancies built in (Boeing's sin, Airbus is smarter, they have 3 AOA sensors on their airplanes). As for trading, I assumed most of us here are retails and probably don't have the firepower to fight the GS, HFT... For many perhaps it is better to trade where the whales find it not worth their while to play. Best regards,
Save me the drama, if the polished turd (a term I'm using in hyperbole for a multi billion dollar project) had correct software advising the pilot, it would not have fallen out of the sky, point blank. There's plenty of "compromised" hardware flying out there, you don't hear about it because it's patched well enough to not fall out of the sky. This plane would still be flying and we'd be none the wiser had the right software been applied, so don't necessarily agree the product was a failure from top to bottom. I agree that lobbying from companies to dismantle regulatory bodies needs to stop, I just don't know if the FAA would've caught this particular issue.
Simple is never simple when done properly and complex is usually much more complicated. The market is full of exceptions and non-standard situations. What information are you looking for?

How do I link up my excel calculation/outcome and input to my brokerage trading platform to trade automatically; how do I automate realtime download of brokerage data into excel.
It entirely depends on the platform and Excel will never be a solution for full unattended automation. Start reading about the brokers API and what they offer.
