Way to change existing chart from one data source to another data source (ex: Google to Yahoo)

[Christine]

Hello,

Is there a way to change existing chart from one data source to another data source (ex: Google to Yahoo) but keeping all the existing techcnical analysis (drawings, notes, etc...) and chart setting?

Unfortunately the answer is no. The reason is that both Google and Yahoo use different scheme to name tickers. While for US and Canada tickers used by both Yahoo and Google are same, it is not true for other markets and so Stockalyze cannot provide a uniform way to use symbol of one with another.
BTW, are you still facing data update problem with Yahoo symbols?
