Is there any way we can know which chart is visible ??
Yes there is. Please click here and scroll to the bottom. There are two files named boost_1.mq4 and boost_2.mq4. Download them and look inside. Go for boost_2.mq4 (to make it short). They both offer a skeleton for exactly such an issue as you describe. Both files are written by me becaue I once ran into an equal issue as you described.

I have multiple charts open at a time and many objects are attached to each chart , because of too many objects are updated on all the charts results into to much use of my CPU cycles almost 25% of CPU ,
with the help of IsChartVisible() , I want to limit object to update on chart which is visible to user only and If i switch to new chart , Object will be updated on this new chart only.
so is there any way we can know which chart is visible to user??? something like ChartIsVisible() ???
