Anytime a client brings this kind of energy to a project up front it's a red flag to being involved. I offered some expert level advice that went way over your head. So be it.
Impressive, is this still going, I was asked to look at some code last month, first thing was run the backtests using experience level datasets, not the garbage most people run, found a massive hole in the strategy which netted to zero by year end after making initial profits, but this year it's already zero initial profits. What does this mean, give it a some months and you will understand, there was a movie once with father and daughter psychologists, they disagreed with the father saying he has more experience, the daughter replied "you could have just been wrong for longer", this is the essence of everyone's belief they have something that works. The other answer is "get off you fat lazy backside and code it yourself", I had to learn C# years ago to transition the hedge fund architecture from Tradestation which ran the proof of concept for a couple of years to support HFT level, in case the world imploded which it is, you can generate profits in Flat / QE / QT / Manipulated markets because it sits under the capacity of the exchanges.
Take a look in the mirror and stop projecting. Ask yourself why you may be experiencing the energy you perceive from me on this thread and other threads for that manner. I've worked with a ton of programmers ranging from professional firms to freelancers on UpWork and similar. All paid work. Never had any issues at all and always received great feedback and have used several of them multiple times, so clearly they disagree with your perception. I'm usually a very polite and friendly guy, but I do not necessarily respond in a friendly manner when people are condescending and act like they're experts on something they know very little about - which is usually the norm on ET.
