I am trying to append new values to input from an iframe. The iframe is a chart and what I am trying to append to the input is a different currency.
For example, instead of EURUSD, I would like to append GBPUSD and the chart refreshes automatically with the chart of GBPUSD. You can also do this by entering the symbol name from the keyboard which requires some time and knowledge on the symbol of different trading instruments.
