11:08 @Ensign_Howard: if we sync at zero, then counting by 3 we get 3, 6, 9, 12, 15 etc

11:09 @Ensign_Howard: if we sync at 1 then count by 3 we get 4, 7, 10, 13, 16 etc

11:09 @Ensign_Howard: you have two sets of times in the same data set because of the change and thus the data is kind of duplicated.

11:09 nigel1964: ok makes sense

11:09 @Ensign_Howard: here is the solution, press the = key to jump to the end of your chart and you probably have some data that is OK - move a bit leftward, of that good data but not into the duplicated data. Then right mouse click and use menu Delete | Delete Left and we will erase bars leftward, both good and bad ones. But since we have refresh we will then use the pop-up Refresh menu for Maximum to get good ones back and then your chart will be clean and problem will be solved.

11:12 nigel1964: one more q - how should I set the synch time if I want YM chart to start at 8:20 EST?

11:13 @Ensign_Howard: go to Setup | Symbol Properties

11:13 @Ensign_Howard: click on YM on the list and edit the Sync time

11:13 @Ensign_Howard: I usually have Sync time be identical to 1st open time
