Thanks elihayun
I am playing with the scripts you posted'

I need a clarification..Can i modify the script so that once executed it should buy a specific symbol irrespective of the chart symbol to which it is attached...

I meant If I attach your buy script to USD/JPY or any other chart...the script should always buy only specific symbol (eg AUD/JPY) irrespective of the chart to which the script is attached..

Thanks
Crore
