I need to find out what i am missing, the following function takes screenshot of the chart in mt4 and posting it in the Telegram group. the problem is it takes screenshots of all open charts. But i need to take the screenshot of the First chart i.e., ChartFirst() only, as and when call the function it should take only one screenshot and post it to telegram, can some one point out the missing element here. thanks in advance
