Hi Programmers!

I'm working on an Amibroker indicator. I realised an interesting problem with the view of chart displaying.

When I'm scrolling the chart, sometimes my indicator lines stop working and shows different values.

I show you three pictures:







You can see, the cursor is always on the same bar: 2008.03.03. 16:00:00

The first and the third pictures show the chart displayed well. But on the second one, all of my lines goes to wrong.

I don't know the cause of this occurrence or how could I avoid it.

Do you have any idea? What can I do? Why doesn't display my indicator well?


Thanks in advance!

I wrote that program. It's not only an indicator, but a part of a strategy.

Don't know what you mean on fix. I had problem with it, but I founded the solution posted earlyer.
