I started with one of these “cheap” programs, because by logic I first had to see if I could make money. So unlike you I would not start by hiring people to program something that never proved to be working.
When I made real money I let a few different programmers program parts of my system.
After that I posted three questions that you apparently did not read. I asked advice to improve my security. I never said I didn’t want to spent money. I know that things cost money. I only asked what I could do.
Your Porsche anecdote has a negative undertone. I know your are smart and I am stupid. But real smart people don’t tell other’s they are stupid. That’s why I will stay silent.
I’ll provide an answer now that we know enough to answer your question.
1. Stop using third party trading platforms.
2. Find a broker with API access, InteractiveBrokers is probably the most used by hobbyists so you can find the most support info from others on the web, but the brokerage customer service isn’t the best. There are many others out there as well.
3. Hire a software developer and have them write the code for your trading system in the appropriate language for your latency requirements, or write it yourself if you know how.
Note that this would be a poor answer if you were trading $10K and getting 25% a year out of it. The cost would far outweigh your profits. It’s a good answer if you’re making $100K a year as you indicated, since the costs would be a small percentage of your profits. Since you didn’t provide this information initially it wasn’t possible to provide a good answer. This was pretty much the entire point of all my posts on this subject.
I make no value judgements on your intelligence and apologize if that is how you perceived my posts. I happen to know a lot about software development and trading software, which is why I offered my time to provide answers to you on this post. I'm certain I'm not smarter than you in many areas, however I do have experience in this area that seemed to be relevant to what you were seeking. I am trying to improve how I come off though, so if you let me know what I posted to make you think I thought you stupid it will help me be a better poster going forward.
BTW, I don’t own a Porsche, and I not only don’t have LoJack I generally leave my car doors unlocked because my cars have nothing of value in them, are worth less than those around them, and I’d rather someone riffles through the change drawer then pops my lock with a screwdriver. Hopefully that helps with the negative undertones, I really didn't get that part either so happy to be illuminated on it.
