The problem of capital flow has nothing to do with inflow and outflow in essence, because every transaction means there is a seller and a buyer. The seller means the outflow of funds to the securities market, and the buyer means the inflow of funds. Each capital inflow = each capital outflow, that is, the net capital inflow is zero for each transaction. However, considering that institutions and large households are often controlled by them because of their different financial strength and well-informed, we need to pay attention to the capital flow of this specific account, which is what we often call the main capital. & lt/SPAN>。 The accuracy of capital flow is not 100% accurate, but can only be said to be relatively accurate, mainly depending on how he calculates capital flow. At present, the more accurate calculation method of capital flow is the reduction method one by one, so I won't introduce it because of the complexity of calculation. I only recommend the software that uses this calculation method to calculate the capital flow at present, mainly wind information and great wisdom. You can see the capital flow by buying their paid software.
