Its basic stock trading software is to reveal information in real time (including market information and information information), so the early stock trading software is sometimes called market software. The essence of stock software is to give numbers (reports), shapes (index charts) and characters (information links) according to a certain analysis model through the statistics of market information data, and users will explain these conclusions according to a certain analysis theory. There are also some stupid and easy-to-use software that will directly give advice on buying and selling.
