Does anyone have an EA that shows buys/sells on the chart?

 

I tried to add text and label objects, but they don't seem to display. Has anyone seen an EA that displays the buys and sells on the chart that you drop it on?

Also, in the Strategy Tester, you're supposed to click on the "Open a Chart" button, and that chart should show you buys and sells if you add the colors to ObjectClose and ObjectSend, which I did. The chart opens, but there are no buy/sell arrows. What could cause this?
