indicator create error

[propfirmedge]

i used a custom indicator in my ea called super trend signal. basically it gives an up arrow for buysand a down arrow for sells..
for some reason when i load the ea i get this error and it doesn't take any trades

i saved a tester.tpl file as a template so it loads the indicator in the strategy tester
what am i doing wrong?

You should also put the indicator in the MQL indicator folder

its in the market folder... so that would be why! Thanks
