Does anyone have an indicator for ThinkorSwim that will display relative volume correctly? That is, rather than just comparing the current time frame's volume to the past "X" bars' volumes (which is what the default relative volume study does), the study should compare the same time slice across "X" number of historical days. For example, if looking at 5-min bars, and there were 10,000 contracts exchanged during the 5-min period from 11:50 to 11:55, but the average volume of the 11:50 to 11:55 period over the past 30 sessions is 15,000 then it should show the volume for this 5-min slice as -5,000. Would also be nice if there was a line graph overlay that showed this in terms of % (in the foregoing example it would be -33.3%...i.e., -5,000/15,000). So bar chart showing true relative volume in terms of contracts, and an overlaid line graph showing the implied % variance from average. If this doesn't exist...is anyone skilled in the TOS programming language?
