上證指數和深成指中的vol是怎樣計算出來的?

“主動買賣盤資金”指標

==================================================

量:=VOL,;

額:=AMOUNT/10000000;

AA:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));

主買:=IF(CLOSE>OPEN,AA*(HIGH-LOW),IF(CLOSE<OPEN,AA*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));

主賣:=IF(CLOSE>OPEN,0-AA*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-AA*(HIGH-LOW),0-VOL/2));

換手:VOL/CAPITAL*100;

流通盤:CAPITAL/1000000;

流入資金:ma(主買,4);

流出資金:ma((0-主賣),4);

bb:=(主買+主賣);

STICKLINE(流入資金>流出資金,流入資金,流出資金,6,0),COLORRED;
