void OnChartEvent question
The object name is in the sparam parameter, you do not need to guess it. Add some Print statements to the event handler to learn if the event is fired or no.
just for curiosity what's the RefreshRates(); doing in your code ?

Hi Guys
could you please have a look at the below code and let me know what is the problem? this expert supposed to calculate some information when user drop the Rectangle on the chart! it works fine when i put the Rectangle for the first time but when i put another Rectangle, it doesn't work .... when user put another rectangle on the chart then 1) expert should clean everything and then calculate everything and draw the lines from beginning based on the new rectangle
