Tong Daxin can do it, but first, you should do a good job in the sub-graph index of the volume ratio, then click on how to open the K-line of the time-sharing chart and press "/"to select the sub-graph index. You can see all the indicators in one minute with the K-line.

The following is the ratio formula:

TT:= IF(HOUR & gt； 12, (hour-13)* 60+ minutes+120, (hour -9)* 60+ minutes-30);

P:=IF(ISLASTBAR，BARSLAST(TT= 1)，0)；

T:=BACKSET(P，P+ 1)；

VV:=IF(T= 1，V，0)；

Ratio: dynainfo (17) * (sum (vv, TT)/TT)/(dynainfo (8)/from open);
