[amibroker] Re: How to Enlarge BUY and SELL arrows on Chart

["electricwally77" <soundmaker@xxxxxxxxxxxxx>]

Hello Edward. Thank you for helping. Please bear with me I am not a
programmer but learning. I simply took two of the lines of code you
sent me which are :
 
PlotShapes(IIf(Buy,shapeUpArrow,shapeNone),colorGreen,0,L,-15);
PlotShapes(IIf(Sell,shapeDownArrow,shapeNone),colorRed,0,H,-15);

I placed these in my Formula Editor File along with the code to my
system and received an error message which said:

Variable 'buy' used without having been initialized.
Variable 'sell' used without having been initialized.

Just curious what I need to accomplish to enlarge the buy and sell
arrows. Thank you.
