error loading data with add()

[slocumtrader]

Hello,
I'm trying to load the $TICK data into my script, ie.

Add("$TICK", PeriodType.Minute,5);

in the Initialize method but I'm getting this error when backtesting in the output window.

**NT** The strategy 'IntradayEngulfingReversal/11db4ee20b7c4cf699b86b1497794125' has called the Add() method with an invalid instrument. Either '$TICK' does not exist in the Instrument Manager or the specified exchange has not been configured.

I have $TICK data in my charts but doesn't seem to work here. Any suggestions?

Thanks!

slocumtrader, please try Add("^TICK", PeriodType.Minute,5); as call instead.
