Left Right Button

Hello!

I do not know if this is an indicator or not.

Input:

1) I write the symbols: EURUSD, GBPUSD,  XAUUSD, ...

or

2) It is given in the input tab, every symbols which are tradable on my broker(Pepperstone), and there I can select some symbols.

What to do?

1) There should be on the right upper corner small left arrow, and right arrow.

If I press the right arow, the chart should be changed to the next symbol in the pre chosen symbols as above.

If I press the left arow, the chart should be changed to the previous symbol in the pre chosen symbols as above.

* Of course, the indicators in the chart should stay same.

* Pepperstone dose not have crude oil, but the crude oil changes it's symbol name.

In this case I hope our arrow go smoothly... 

* I hope, if I press the left/ right button on my keyboard, the same should happen.

Of course it's OK, for example control + left/right arrow on my keyboard.

Thank you for reading.
