MOS main capital = transaction amount × [(closing price - lowest price) - (closing price - lowest price)] / (closing price - lowest price).

The calculation method of the mos main fund formula is to evaluate the strength of the main fund flow based on the position of the closing price relative to the price range and the size of the trading volume. Specifically, the mos main fund = transaction volume × [(closing price-lowest price)-(closing price-lowest price)]/(closing price-lowest price). If the mos main capital is positive, it means a net inflow of main funds; if the main capital is negative, it means a net outflow of main funds.
