Problem Plots

[eDanny]

In 6.5 if you used something like DrawDot() you would have to test to see if the dot should be removed if the condition changed. It was always much easier to use a dot Plot which would automatically be removed if the condition changed. With NT7 I am having problems with dot Plots on an oscillator line which sometimes persist when the condition goes away. These work perfectly in NT6.5. I have tried a number of ways of recoding but can't get to the bottom of the problem. Did I miss something very basic in the changes for NT7? Of course refreshing the chart fixes it up to that point but the problem comes back.

eDanny,

Try removing all indicator logic and just have very basic condition that will turn to false and should theoretically turn your dot off. See what happens on this base case.

Here is a sample indicator I just made by combining Stochastics and MACD which illustrates the problem. It is in the bottom panel on the chart. If the plotted line temporarily plots in a position and a dot plots, sometimes when the line moves the dot persists.

Suggest you print values of your plot to see if they are actually updating based on your logic.

Not sure I understand why. Seems every indicator I have from 6.5 exhibits the same behavior, and they all work correctly on 6.5.

eDanny,

Things have changed on 7 and as such indicators need to be converted. Just because it worked in 6.5 does not guarantee it will work in 7 as-is. First step is to see if your code blocks are even being evaluated hence the prints.

Thanks for the reply Josh. I know there are changes but this has nothing to do with any indicator breaking code. This is straight forward testing and plotting and the sample code I sent was just made up from two standard NT7 indicators. If the chart is refreshed (F5) every plot is correct. In real time they are not updated correctly and there is no convoluted code involved.

eDanny, I just spent some time trying to figure out what is happening here. I believe the code behaves exactly like it is supposed to. I edited your code a bit to add some print statements to verify. Please try the attached code and notice how an OnBarUpdate() does not always result in a dot being re-drawn.
