However, I would like, when the up/down arrow keys are used to change the chart symbol, that the indicator ALSO changes the symbol of ALL other open charts to the new symbol. I do not want the left/right arrows to change the timeframe of other open charts, as these will be the same chart symbol on a different timeframe already.
The idea being to press the up/down arrow key to change the symbol, and it will update all open charts with the new symbol, thereby allowing me to scan the action on multiple open timeframes at the same time, before moving on to the next symbol...
