This is another case of software devs thinking they can crack finance/trading because they know how to code. The myopia comes from the difference in culture and how risk is treated from tech organizations to finance.
Exception is if you have an advanced math/physics degree that will be useful in the domain of quant shops but I wouldn't recommend someone taking that route just because they want to make money.
There are lot of finance/trading jobs. I wouldn't waste time pursuing that field. Very few end up parachuting with a mid six digit figure salary even inside that industry and these are people with many years of finance specific experience.
