I want to add functionality for the attached indicator below. Specific requirements:
1. Select the currency to be displayed, (add a column of options buttons to display the desired currency)
2. Quick conversion to other currency pairs (add 2 button columns, when I want to convert to USDJPY pair I will choose USD in column 1, and JPY in column 2; then if I want to choose NZDUSD Pair I just choosing NZD in column 2 without choosing USD in column 1). Change all open charts at once to the selected curency.
In a nutshell, I want to add 3 button columns representing the selected currencies. Where column 1 is for selecting the currency to be displayed. Columns 2 and 3 are for quick change between trading currency pairs (on all open chart).
