[amibroker] Plotting Seasonal Trend for multiple symbols in a single indicator

[Padhu]

This is just a starter step, but would like to know if this approach is correct 
to plot Several Horizontal Lines along with Symbols to plot seasonal trend for 
various currency pairs. Eventually I will get all bullish months for a symbol 
into a single line. 

barcolor_daily = IIf(USDCAD AND MONTH==SEPTEMPER,colorGreen,colorRed);

barcolor_daily = IIf(USDCHF AND MONTH==OCTOBER,colorGreen,colorRed);

PlotOHLC( HaOpen_1hour, HaHigh_1hour, HaLow_1hour, HaClose_1hour, "", 
barcolor_1hour, styleCandle ); 

Plot( 1, "", barcolor_daily, styleArea | styleOwnScale | styleNoLabel, -0.1, 50 
); 



Thanks,Padhu
