[amibroker] Displaying correct indicator setting dependant on which symbol is loaded?

["Steve" <avalon-ardy@xxxxxxxxxxxxxxx>]

Hi,
I 've a formula that maps the daily open on Forex & places price bands around the open. 
For all 4 decimal crosses the band is set to 0.0005 but for JPY crosses this has to be 
0.5. How can I have AFL select the right value dependent on which symbol is being 
displayed?
eg.
For 4 decimal crosses such as GBP/USD etc

Plot(dao,"Daily Open",colorDarkBlue,styleNoRescale +8+16); //
Plot(dao + 0.0050,"",colorBlueGrey,styleNoRescale + 8 + 16); //daily Open bands +ve
Plot(dao - 0.0050,"",colorBlueGrey,styleNoRescale + 8 +16);//daily Open bands -ve

For 2 decimal crosses - USD/JPY etc

Plot(dao,"Daily Open",colorDarkBlue,styleNoRescale +8+16); //
Plot(dao + 0.50,"",colorBlueGrey,styleNoRescale + 8 + 16); //
Plot(dao - 0.50,"",colorBlueGrey,styleNoRescale + 8 +16);


thanks
