Arrows on charts

 
How do you make an EA create a buy and sell arrow on the chart? I've had EAs that do this, and the latest one we've made doesn't do it. Is there something in the code or is it the environment settings? http://www.eesfx.com
 
OrderSend(..., color arrow_color=CLR_NONE)
arrow_color - Color of the opening arrow on the chart. If parameter is missing or has CLR_NONE value opening arrow is not drawn on the chart.
