What software do Americans use for stock trading?

The compass is terrible. The trend was not good years ago, and it has been losing money. I don't think I can do it without good tools. I chose the compass stock trading software and spent 1.8 million. I made a promise before buying the software, and the customer service was very enthusiastic. I like it, too, just like a group of compasses. And then it was over. There is no profit margin promised at the beginning. It was agreed to recommend stocks, which were basically not fulfilled. After using the software for a month, I lost another 20 thousand. Finally, Compass felt responsible, saying that it only needs to pay another 50,000 yuan a year to recommend good stocks. I am dizzy, my money is gradually decreasing, and the compass's money-making model is refurbished. I was dissatisfied. I asked the customer service in the group why there were good tickets that were not recommended to us, or even chain charges, and I was kicked out of the group.

Remind everyone that you must be careful when buying stock trading software. The general trend is not good, any software is useless, and any promise is not credible!
